What is a Drill Doctor used for?
The Drill Doctor is a drill bit sharpening system owned by Professional Tool Manufacturing LLC. This system has revolutionized drill bit sharpening for everyone and can restore even the dullest of drill bits back to near-perfect conditions.
The Drill Doctor is most efficient at sharpening a drill bit’s original point angle and easily does so with high-speed steel (HSS), carbide, and even cobalt steel.
Benefits of using a Drill Doctor
Important parts of a Drill Doctor you should know
A drill doctor’s chuck is a specialized clamp for holding bits with radial symmetry, especially those that are cylindrical in shape. Chucks like what’s in the drill doctor is a common mechanism in rotating tools and can either be two or three-jawed depending on the model.
You can also sharpen left-hand drill bits with a dedicated Drill Doctor Left-handed bit, chuck.
The Drill Doctor’s carefully constructed alignment port produces geometrically accurate drill bits. Since most bits have either 118° or 135° point angles, this mechanism allows you to set the bit position in order to get the most precise results.
The bread and butter of the system. The sharpening port is what accepts the drill bits and what houses the sharpening wheel. Dotted with a cam guide, the sharpening port is what’s also responsible for ensuring that your bits are not sharpened skewly.
Part of the system that allows you to tackle split-points. Split-point drill bits lift away debris more easily and drill holes faster with lower chances of snagging. The splitting port lets you easily work on drill bit splits in just a few quick turns of the chuck.
Differences between Drill Doctor models
The Drill Doctor sharpening system is comprised of a line of tools, but among the most notable ones are the top three:
The 350X is the entry-model unit and is the best choice to familiarize yourself with the system for a new DIY’er. With a price-friendly tag, it’s a good option when first learning the ropes of DIY. Small yet sturdy, this tool is a drill doctor with a chuck to sharpen up to 3/4 bits.
It doesn’t have an alignment port, so it works in a pretty straightforward manner, especially for bits with 118° point angles. It comes with an industrial-grade diamond sharpening wheel, making it more than enough for light shop and home use.
The mid-tier of the Drill Doctor line. More capable and versatile than the 350X, the 500X is better suited for serious DIY’ers and hobbyists, as well as budding professionals.
It can handle up to ½” standard bits but takes on more material including HSS and black oxide steel. It has a longer chuck for more precision and stability as well as the addition of a 135° point angle position and an alignment port.
The 750X is Drill Doctor’s top-line model. It combines the abilities of the previous two models and cranks it up further. Working at record speeds, this tool sharpens standard twist and masonry bits up to ¾”. It offers custom point angle sharpening from 115 – 140°.
With adjustable material take-off, push-to-stop functionality, and the addition of a splitting port, the 750X is your all-in-one when it comes to precision, high-quality drill bit sharpening. To add, despite being the premium tool, its price is still quite manageable.
Can a Drill Doctor sharpen masonry bits?
Yes. A Drill Doctor has no problem working with a range of drill bits, even those sourced from tougher material. Masonry drill bits, while often sturdier than regular ones, are easily handled by the 500X and 750X.

These are the step-by-step procedure on how to sharpen drill bits with a Drill Doctor 350x:
How to use a Drill Doctor 500x?
The basic operation of the 500X works in pretty much the same way as the 350X, only that there’s the addition of point angle selection through an alignment port.
How to use a Drill Doctor 750x?
The 750X is basically a vamped-up version of the 500X. It has all the same features and further improves upon them, along with the addition of adjustable material take-off and a higher range of point angle sharpening. The first two guides showed us how to place, align, and sharpen bits respectively. So now, here’s a quick flow of how to use a drill doctor drill bit sharpener 750x:
Note: material take-off allows you to select whether you wish to remove more or less from the tip. And if you want to know how to sharpen left-hand drill bits with a drill doctor, use a left-handed drill bit chuck instead of the regular chuck.
Other ways to sharpen drill bits
When it comes to cost-efficiency, nothing beats a dedicated drill bit sharpener. The Drill Doctor is simple and effective with an acceptable price tag. If you’re looking for something less or more, then consider these other options:
How to maintain your Drill Doctor?
Now that you know how to use a Drill Doctor 750 and other models maintenance is relatively easy. It mainly involves of the diamond cutting wheel. After sharpening about 25 drill bits, material dust will accumulate in the grinding compartment which can cause wear on the sharpening port. Unplug the tool and open the wheel access.
With the cover down, gently shake the dust particles off and into a disposable container, then just brush away any that was left behind. Use compressed air or a brush to clean the chuck. Consider replacing the grinding wheel after about 200 sharpenings.
Dos and don’ts when using a Drill Doctor
Are there any safety concerns when using a Drill Doctor?
Luckily, using a Drill Doctor is pretty safe. There are no exposed gears of blades that could cause injury. To maintain relative peace, just keep in mind the following:
- Always make sure that the chuck is properly aligned and tightened before actually sharpening to avoid misaligned jams and accidents. The sudden backlash from the grinding wheel may cause a bit to suddenly fly off at dangerous speeds if not secured.
- Work slowly and precisely, avoiding too much pressure and haste to reduce the risk of damage and accident.
- Mind the cord as it’s often not too long.
You really can’t compromise the health of your drill bit and a well-invested cordless drill. When we’re sick, we see a doctor. The same could be said about drill bits – once they’ve grown weary and dull, it’s time they got a visit from a Drill Doctor.
Sharpening bits can be easy and quick even if done manually, but if it’s speed and quality you’re after, nothing beats an electric drill bit sharpener.
