Why Sharpen a Drill Bit?

Over the course of repeated usage, a drill bit will unavoidably begin to dull. Using a dull drill bit can result in overheating, uneven and unclean cutting, and even tool breakage. A sharp drill bit provides optimal efficiency and drilling performance. Without sharpening a drill bit, it will require replacement, costing the operator unneeded expenditures of money and time.

• When you’re getting started on a project, and your 118° drill just isn’t ‘cutting’ it, within a couple of minutes you’ll transform that 118° into a 140° point, or another angle; get your job done, and put it right back to 118° again.
• When that job you’re working on absolutely has to be done today, and the only drill you have in the right size just won’t make it to the finish line, go ahead and put a brand new point on it and keep poking those holes! When you have a drill bit sharpener, you won’t need to wait for the delivery of its replacement.
• Using a sharp drill will result in a smoother surface finish and better accuracy, when compared to using a dull or chipped drill bit.
