Your quick expert drill bit tip
Aaron Barnett of BangingToolbox suggests: The best drill bits for metal are made from Cobalt and are made by TPP, Irwin, Milwaukee, and Dewalt.
If you get the best drill bits for metal then the bits will also perform when drilling other materials like wood.
There are 2 philosophies for buying drill bits.
- Buy the cheapest drill bits in bulk as all bits eventually break.
- Buy a quality set that won’t snap or blunt as easy and pair up with a drill bit sharper like the Drill Doctor 750X to get the longer life value from your drill bits.

What defines drill bits?
Drill bits are useful for anyone who needs to do any kind of building, construction, repair, or DIY work.
There are so many different drill attachments you can use in your Makita, Dewalt, Milwaukee cordless hammer drill to drive screws and drill different-sized holes in different building materials like glasses.
If you do a lot of drilling, you will probably be going through drill bits like crazy. Consider valuing the worth of spending more on the best quality drill bits you can discover.
Even though some bits are more expensive, superior quality cobalt steel lasts longer, so you won’t have to buy new bits too often.
Don’t forget to get a first class, sturdy case as well. While a case will keep you from losing bits, a nice container will also help you transport your drill bits making life easier when needing to find the right type or sized bit.
If you are going through a lot of bits you might want to get a drill doctor to resharpen the tip when blunt.

What attributes did we compare in our review
- Strength. Your drill bits should be able to handle almost any material with ease. Drill bits that can bore through brick, stone, concrete, and metal can just as easily bore through wood and plastic.
- Durability. Carbide-tip drill bits are not only strong but will stay sharp for longer.
- Size. You need to purchase drill bits in a variety of different sizes. This will enable you to drill holes that are sized appropriately for specific purposes.
- Flexibility. Some degree of flexibility is actually desirable and can prevent snapping or breakage when you have to drill at an angle.
Factors we found to be most important in out tests
1. Consider the brand.
Irwin and Milwaukee drill bits are among the best-made and most reliable drill bits available.
Most Irwin drill bits are perfectly suited for drilling into metal, and the best are even able to penetrate hardened steel fairly easily.
The cobalt alloy construction is resistant to heat and abrasion and retains a sharp tip for a longer time.
Milwaukee matrix carbide drill bits are equally durable and are especially resistant to impact.
These drill bits are designed to absorb peak torques, which prevents the build material from wearing out too quickly.
2. Have you got bits that are durable enough?
The materials from which the drill bits are made have a lot to do with their durability. Cobalt is an especially reliable and hardy material, and you will find that drill bits made from this material are extremely hard and long-lasting.
Cobalt also dissipates heat quickly, which reduces the risk of overheating when drilling through metal.
Consider purchasing drill bits with a black oxide coating. These are resistant to corrosion and will bore through most any material efficiently.
Titanium-coated drill bits are even more resistant to friction and stay sharp longer even with frequent use.
For maximum longevity though, carbide-tipped drill bits are among the most durable you can buy.
3. Is the drill bit long enough?
The length of your drill bit will affect how efficient and how effective it is for specific tasks.
Shorter drill bits tend to be stronger than long bits, and are less likely to go off-center when drilling. However, short bits may not provide the depth needed for certain drilling jobs.
4. Have you got a range of widths and sizes in a kit?
Size is an equally important factor. Drill bit size is usually measured in fractional inches, wire sizes, letter sizes, and metric decimal millimeters.
A phenomenal idea is to get drill bits in a few different sizes so you can drill holes of varying diameters right when you need to.
5. Consider tip styles.
Drill bits also come in different tip styles. Twist drill bits usually come with standard drill points, which are suitable for most general drilling tasks. You may also see twist drill bits with split drill points, which ensure more stable operation and better penetration.
Then there are V-point bits, which are used for drilling thru-holes in sheet metal, brad point bits, which are useful for drilling blind holes, fishtail bits, which are perfectly suited for drilling at an angle, and taper point bits, which are used for drilling tapered holes.
Counter-bore drills come with tips that have flat blades that extend from the center to the outer edge. The bits may come fitted with outer spurs or “teeth” which help prevent chipping and splintering.
Countersink drill bits also have similar flat blades that extend from the center to the outer edge. These have angles that range from 60° to 120°.

6. What price point to expect?
The best drill bits can be quite expensive, but spending on the cheapest bits is rarely a first class idea. Cheap drill bits tend to break easily and lose their sharpness quickly, so you will have to buy new bits more frequently. Even if you have a drill bit sharpener, cheap bits will require more frequent sharpening and will become totally useless sooner or later.
Get the best drill bits you can buy, and get longer use from each bit if you sharpen your drill bits periodically.
When to use metal drill bits
Metal drill bits are the only serious choice, whether you are a hobbyist/DIY’er, or a professional chippy/steelworker.
Standard wood-only drill bits work for drilling wood and plastic but will be useless for anything else like soft and harder metals.
On the other hand, metal drill bits will work equally well for softer materials and steel, so you can use the set for pretty much anything.
There are a few different varieties of metal drill bits. The most popular are made of cobalt, which can carve through aluminum and stainless steel.
There are also drill bits that have black oxide coatings. These are durable, stay sharp for longer, and can bore through almost any type of material.
Titanium-coated drill bits are also durable and produce little friction.
For sheer strength and durability-though, carbide-tipped drill bits are hard to beat. And stay sharp for much longer than any other type of drill bit material.

Irwin drill bits vs Tpp Hard
Irwin 3018002
The Irwin 3018002 is a 29 piece-set of heavy-duty drill bits, each designed to drill into the toughest materials.
Made of 8% industrial-grade cobalt alloy, these drill bits can bore through-hardened steel and be an experience like cutting through hot butter.
The set includes drill bits in various sizes, ranging from 1/16” to 1/2”. This gives you a first class range of options in hole sizes, which are suitable for woodworking and even metal fabrication.
The set comes with a rugged over-molded case made of rubber, which keeps your drill bits secure and organized.

TTP bits
I found that the TTP bits have excellent heat and abrasion-resistant properties and are equipped with tips that penetrate steel readily.
You don’t have to push hard to penetrate through the material you are working with, and the drill remains steady and centered on the drilling point.
I like having a unique set that not many people know about yet.
When to use a step drill instead
When you want to step up a hole to a bigger and large size a step drill can be used as a way to grow a hole in the metal and keeps a tidy centered finish. This is useful when installing new hardware on aluminum doors and windows.
#1 Step drill
The Milwaukee 48-89-9257 Impact Step Drill Bit Set is a 3-piece set of high-speed steel drill bits that have a unique futuristic design.
Made of Titanium-Aluminum-Nitrite, made to have 5X longer life than its competitors. The Rapid-Strike-Tip™ and dual spiral flute are made to also drill 2X as faster than its competitors.
These drill bits are tough enough for electricians. The Titanium Aluminum Nitride (TiAlN) coating further enhances edge retention and ensures the long life of the bits.

The unique design of the Milwaukee step drill bits enables you to drill a wide variety of differently-sized holes, even with a fairly modest number of tools.
The shanks are compatible with chucks and impact drivers. So you have a great deal of flexibility with regard to the drills that you will operate with.
Step drill bits have non-walking tips that help you keep the tip centered when drilling on slick and glossy surfaces such as steel and aluminum sheets.
I like how these drill bits are also equally effective on plastic, and a variety of other materials, although the material should be thinner than the height of each step on the drill bits.

How to quickly drill larger holes in wood
Auger bits look pretty much like twist bits, with the main difference being a large flute that clears out wood or metal chips from the drill hole. The design also has screw tips in most that help keep the drill bit centered when starting a new hole.
Like spade bits, auger bits are best suited for wood and soft materials. Te drill bits do make cleaner and smoother holes than spade bits and don’t need as much torque to operate.
If you are ready for auger bits, look into the Irwin brand as an inexpensive and versatile set, their performance is flawless. I use these to not damage or blunt my more expensive drill bits for holes in timber framing.
For quick and easy drilling into wood, consider purchasing a set of High-Speed Steel (HSS) bits. That will drill into a wide variety of materials including wood, PVC, fiberglass, and even aluminum.
Irwin Speedbor Max
Irwin’s Speedbor Max set offers high performance and precision in an affordably-priced set. Consisting of ten 6-inch long drill bits in sizes ranging from ½” to 1 ¼”.
Three of the bits are fitted with three cutting spurs that enable you to drill holes faster and cleaner, with reduced risk of a breakout. This design also ensures a longer drilling life.
The drill bits have full screw-point tips that enable self-feeding, making drilling faster and more efficient. The tapered tri-flute design helps eject chips faster and reduces incidences of binding.
Speedbor Max drill bits have ¼” quick-change shanks that prevent slipping when used with standard chucks.
I like how these bits are compatible with all ¼” quick-change chucks in impact drivers and can be used in standard cordless drills as well.
The Irwin speed bore drill bits will save the wear and tear on your main drill bits and will instantly drill through timber-like butter.

Larger holes for cheaper Irwin bits
A cheaper option is the Irwin Speedbor set of 16 spade bits plus a canvas case. The bits range in size from ¼” to 1 ½”, giving you a wide range of options for drilling holes of various sizes.
The Speedbor bits are designed for durability and enhanced cutting performance.
This drill bit design attributes a patented “Blue-Groove” design that clears away chips from the drilling surface as you are working, improving speed, and enhancing efficiency.
The bits also have shanks that are 25% larger than that of other brands’ drill bits. This makes the bits more resistant to heavy use and helps increase their usable life span.
A thicker cutting edge works for better performance and the double-cutting spurs help you drill cleaner holes in any material.
Irwin spade bits are a cheaper must-have that let you drill and bore holes for checkouts in timber framing for cables, pipes, and wires quicker than setting up any Makita or Bosch wood router.

How to keep your drill bits sharp?
No matter how strong and durable your drill bits are, everything will get dull at some point, particularly if you often work with steel or other hard materials.
You can use an ordinary bench grinder for sharpening, but something like a Drill Doctor is a more convenient and fail-proof solution.
The best models can sharpen any type of drill bit and are easy to use without prior experience.
Sharpening your drill bits will spare you the expense of having to buy a new set of drill bits every time yours wear out.
Over time, you can save a considerable amount of money by purchasing a bit sharpener.

What tool to use to sharpen drill bits?
The Drill Doctor 750X can save you a great deal of time and money when your drill bits inevitably get dull.
A convenient and effective solution that will save you the expense of having to purchase new drill bits every few weeks, the Drill Doctor is quick and simple to use, yet provides professional quality results.
The 750X accommodates a wide range of drill bit sizes, ranging from 3/32” to 3/4”. Ideally suited for sharpening frequently used bits, a drill bit sharpener can also restore the original edge on broken bits that you would otherwise throw away and not re-use.
The 750X is so versatile and powerful that this monster can sharpen almost any type of drill bit. From high-speed steel bits to cobalt bits, and masonry and titanium-tip bits, the Drill Doctor does it all with consistently excellent results.

When to use a hole saw?
Ever wondered how carpenters and woodworkers drill perfectly round and smooth holes in wood?
In most cases, we use a hole saw on the job on a daily basis. The cylindrical blade with a rigid cutting edge works like a rotating saw.
When attached to a typical drill, these beasts can be used to create knob holes for doors and cut holes for wiring, pipes, and downlights.
Like drill bits, hole saws come in a variety of sizes. The larger the diameter of your hole saw is, the larger the holes you will be able to cut. Most hole saws have a pilot bit that helps keep the blade centered.

The Milwaukee 49-22-4185 set consists of 22 hole saws, three drill bits, and three arbors. The hole saws are made of ice-hardened steel that makes the blades last 50% longer than other similar hole saw kits.
When you need strength and durability to cut through wood and metal, this is an excellent choice for electrical, plumbing, HVAC installation, and various other maintenance and repair tasks.
The cryogenic hardening process is a large part of what makes the Milwaukee hole saws so durable.
Unlike heat-treated saws whose coatings tend to wear out quickly, these are actually strong to the core due to the unique manufacturing process.
The Matrix II bi-metal construction further ensures durability and long life, and the cutting-edge has a precision-ground geometry that makes cutting tasks quick and easy.

What brand makes the best drill driver bits?
The Milwaukee Shockwave 48-32-4006 is a huge 40-piece set of drill bits that should cover you for most any need.
Whether you need to drill 3/16” screw holes or you need to rout out wire holes for an electrical system, there is sure to be something in this set for you.
The Shockwave drill bits have a unique geometric design that absorbs impact, reducing wear-and-tear on your drill, and reducing shock to your hands and arms.
This not only prevents damage to your drill but lets you work for longer periods as well.
The Shockwave drill bits are made of heat-treated steel, which gives the strength to cut through even the toughest materials. This also ensures that the sharp edge is retained for longer periods, and minimizes the risk of breakage.

Who uses drill bits
1. Builders
Builders, typically use countersink bits to create conical holes.
These enable the screwing in of fastener heads that are flush with the surrounding surface. These types of bits also create an angled hole that matches the shape of the screw head.
This prevents splitting when the screw is tightened.
2. Steel Fabricators
Steel fabricators, often use twist bits to drill into metal. With a twist, you can use countersink bits to create holes that allow screws to sit flush with the surface of the surrounding metal so that the head does not obtrude.
For drilling into sheet metal, steel fabricators usually use step bits. These have a stepped design that allows the user to drill holes of different diameters without having to change drill bits.
3. Diy’ers
DIY’ers will find plenty of uses for brad point bits, which are especially useful for drilling into the wood on your exact marked center.
These types of bits can drill cleanly and are able to drill holes with smooth edges and flat bottoms due to their sharp cutting points.
The center spurs aid in positioning and keep the drill centered.
4. Plumbers
Plumbers use twist bits for drilling into metal when attaching fixtures to plumbing systems. More frequently, the use of masonry bits can help efficiently cut through brick, mortar, stone, and concrete.
Carbide-tip masonry drill bits are especially useful for this purpose, particularly those with deep fluting.
5. Electricians
Electricians use fast-speed drilling, and timber auger bits, to drill holes for pass-through wiring. Especially for cases wherein the wiring has to be concealed.
Running wires through walls is a common repetitive task and drilling needs to be quick and fast.

Tips for drilling jobs
The importance of using the right equipment can’t be stressed enough. As mentioned previously, you will get better overall results by using metal drill bits.
Standard metal drill bits can cut through steel and are just as effective for drilling wood, plastic, and fiberglass.
Wear safety gear.
Safety equipment is just as important as the drill bits you will be using.
Goggles, gloves, and even overalls and footwear will protect you from the metal and wood chips and sawdust that will come flying out every time you push the drill in.
Make sure your bit is sharp before starting.
Dull drill bits aren’t only ineffective, but can also jam and break.
Avoid overheating your drill and drill bits.
When working with steel, use a lubricant such as CRC and keep your speed fairly low, this will reduce the likelihood of your bits breaking.
Do you want to drill square holes?
Did you also know you can drill square holes in wood using a mortiser drill bit? Read my square hole drill bit review for more info.
