I sharpen many many items. Just a few are shown here.
I sharpen spiral drill bits from 1/32 inch to about 1 inch.
Drill bits can be used in hand drills or drill presses. I can sharpen smaller bits used in hand drills with four facets (bottom photo above with blue and red facets) rather than the standard two facets (top photo above). The purpose of four facets is to help minimize the bit "walking" when used in a hand drill.
Although difficult to see in the photo, a variety of bits are shown. Included are: An 8 foot self feed bit; a 2 1/4 inch diameter self feed bit, and self feed auger or ship bits. All of these bits came to my shop for sharpening.
