Drill Bit Sharpener (Tormek DBS-22) - The Drill Bit Sharpening Jig Attachment For Tormek Water-Cooled Sharpening Systems.
• SUPERIOR SHARPENING – Produces a true FOUR-FACET GRIND, which allows sharpened bits to be self-centering (eliminating the need to center punch or drill pilots). • WIDE RANGE OF SHARPENING ANGLES – Capable of sharpening all point angles between 90 and 150 degrees. • SYMMETRICAL SHARPENING FOR LONG BIT LIFE – The two cutting edges remain perfectly equal at all times, which allows for true symmetry in sharpening. • ADJUSTABLE CLEARANCE ANGLE – You can set the clearance angle to the optimal range for your needs. 7,9,11, or 14 degrees. • SHARPENS BITS FROM 1/8” TO 7/8” (3mm-22mm) – No need to change jigs for different size bits. • PART OF THE EXCEPTIONAL TORMEK WATER COOLED SHARPENING FAMILY – Use with the T-8, T-7, T-4, T-3, and Supergrind 2000.
For years, professional craftspeople have asked “how can I sharpen my own drill bits?” Tormek, a leader in tool sharpening for more than 40 years, has responded with this exceptional DBS-22 Drill Bit Sharpening jig. For use with all Tormek sharpening systems (T-8, T-7, T-4, T-3, and Supergrind 2000), it allows you to keep your drill bits sharp and ready to work. The four-facet grind this jig produces is worth discussing, as we feel it’s infinitely superior to the common split-point grind other systems produce. The symmetrical four-facet grinding increases bit life, and allows the freshly sharpened bits to be self-centering, making your work a lot easier. Think about it – no pilot holes or punches needed for precision. Plus, a four-facet grind produces a bit that utilizes less torque and generates less heat (70% less heat) than a conventional bit. Another important aspect is this jig is part of a complete water-cooled sharpening system that will make your entire shop’s worth of tools finely honed, while taking less metal off the tools and bits, increasing longevity. You can buy a stand-alone “drill bit only” machine (like Drill Doctor) that produces the inferior split-point grind, or you can have a professional-grade Tormek system with interchangeable jigs like the DBS-22. For people who love good tools and the exceptional work they produce, the choice is clear.

Why is the 4-facet point so beneficial compared to a conventional point?
It considerably decreases the force required on the core of the drill, i.e the chisel edge, which reduces the heat development and permits an increased force to the cutting edges. It gives the drill a dramatic improvement in cutting performance.
