Best Drill Bit Sharpeners

The Drill Doctor 750X drill bit sharpener is built to last.

Designed with professional use in mind, the unit is capable of sharpening bits with the size of 3/32 to 3/4 inches. As for the actual sharpener, the pre-installed 180-grit diamond sharpening wheel does its job fairly well and can be used even on carbide bits.

To make the whole process a bit more controllable, the unit features an automatic Push-to-stop drill point that won’t let you cut the bit too much (if configured properly). The drill point can be adjusted to regulate the amount of material that’s being removed during the sharpening process.

Moving on, let’s take a look at the features that make this little unit stand out among other similar sharpeners. First, it’s the adjustable chuck that can be used to sharpen drill bits at angles from 115° to 140°. With this convenient part on board, you can work with all-purpose and special bits without too much of an effort.

All in all, the Drill Doctor 750X is definitely among the best drill bit sharpener tools thanks to its well-thought-out design and great build quality. The 750X cuts through high-quality metals and steel with ease to match, while the adjustable chuck designed for a variety of drill bits makes this model a worthy choice for both professionals and hobbyists.

Tormek DBS-22 is designed as an attachment to the Tormek T-7 and T-3 water-cooled grinding and sharpening machines as well as other grinding wheels.

Classification out of the way, let’s break down the core features of the attachment itself. The two things that make this tool from Tormek better than the majority of similar models are the symmetrically sharpened cutting edges. Once set up, the cutter sharpens the drill bits and creates equal lips on all sides. Additionally, the tool can also create point angles, 4-facet points, as well as clearance angles, which also adds a couple of bonus points to its overall versatility.

Even though it can be a bit tricky to set up the drill holders for your specific needs, you can always use the user manual to adjust the angle according to your requirements step by step. The manual is as informative and accessible as they come.

Plus, the kit comes equipped with a special base plate that features the recommended angles for all common bit sizes. By using this simple yet highly convenient plastic ruler, you can be sure that all cuts will be precise. Once set and fixed to a grinding stone, the drill bit sharpener will remain stable regardless of applied pressure, ensuring clean sharpening.

If you can’t imagine your work without drilling and are looking for a convenient sharpener for your Tormek system, then this model will be right up your alley.

The Drill Doctor 350X is another model designed for professional use, however, thanks to its relatively simple build, it will also prove accessible for users that want to purchase their first sharpener tool.

For added durability, the unit features an industrial-grade diamond wheel that ensures its long service life. Additionally, the tool incorporates V-block jaws that firmly hold the bits while you sharpen them, eliminating the need for additional chucks.

When it comes to the sharpener’s versatility, it can be used on standard, masonry, and twist bits with sizes ranging from 3/32 to 1/2 inches. On top of that, the tool can be adjusted to sharpen metal bits at a base angle of 118°, which should suffice all standard jobs. Even if your drill bits have to be sharpened at a different angle, you can achieve it by grinding them a bit more.

Thanks to the combination of its high-quality sharpening wheel and a powerful electric motor, the unit is capable of sharpening standard-size bits in under one minute, which is really fast considering its small size.

Wrapping things up, if you are searching for a workhorse of a sharpener, then this model from Drill Doctor will prove a great pick for that role. Precise and reliable, it gets the job done when you need to sharpen your drill bits fast and easy.

The Woodcut Tools sharpener for drill bits is an attachment to the bench grinder rather than a fully-fledged device. But how does this attachment compare to them in terms of sharpening effectiveness? Given a good sharpening wheel, it does not only sharpen the bits quite effectively but also is easier to adjust than most standalone sharpening tools.

First things first, the adjustable bevel enables quick and simple adjustments according to the size and diameter of your drilling bit. Thanks to this, you can sharpen bits ranging from 1/8- to 1/2-inch in size. The exact angle scale goes from 20° to 140°, which allows configuring the bit holder jaw in a matter of seconds. The only issue you may have with the scale is the fact that it wears off rather quickly, so we recommend taping it with transparent duct tape.

Despite this small inconvenience, the attachment can be used to sharpen other hardware including lathe tools, gouges, as well as scrapers, thanks to this universal scale meter.

In the end, this sharpener attachment from Woodcut Tools will be an ideal pick for users looking for an all-purpose tool that doesn’t need any additional alignment. Easy to set up and use on a grinder wheel, it is by far one of the simplest and most effective sharpeners out there.

The Woodstock D4144 is yet another bench grinder attachment that utilizes a slightly different alignment system compared to other sharpening machines listed here.

First of all, the thing that makes this model special is its construction. You have to use this attachment with a belt grinder. However, its mounting requires a slightly different installation method. Once installed, the attachment can be adjusted to accommodate different cutting angles ranging from 49° to 88°, making it convenient to use on bits with different cutter shapes.

The aligning process, on the other hand, can be a bit of a hassle at first since it takes time to unscrew the bolt and then screw it back each time you change the bit. After you've successfully mounted the unit, it will fit drill bits with sizes ranging from 1/8 to3/4 inches including most standard bits.

Furthermore, you can use this model from Woodstock to sharpen other tools including gouges, scrapers, and woodworking lathes as long as their size fits the holding jaws.

All things considered, the Woodstock D4144 drill sharpener is a reliable, budget-friendly solution for users that use their power tools fairly often. Easy to set up and align, the model is effective enough for DIY use. Considering the price of this unit, there is not much more you could possibly ask for.
