Drill bit sharpening range

This attachment sharpens twist drills from 3.00 mm up to 19.00 mm on a standard bench or surface grinder. It automatically sets the correct clearance angle for each bit size. A built-in translation table converts the required overhang into the proper point angle. The unit is designed for use with ANSI, OSHA and UL listed grinders.

Best fit and limits

Suitable for workshops that need to restore dull high-speed steel drills up to 3/4 inch diameter. Not suited for carbide, cobalt or other specialty alloys that require diamond wheels. Buyers who need to sharpen bits larger than 19.00 mm or smaller than #30 should look at a different sharpener.

Max drill diameter 19.00 mm

The 19.00 mm upper limit is the single specification that decides whether this attachment can handle the drills you use. If your largest bits exceed this size the sharpener will not accept them. If all your bits fall within the 3.00 mm to 19.00 mm range the attachment will cover the full set.

Questions about this item

How do I mount the 825 attachment on my bench grinder, and what step is most often missed?

Clamp the unit to the grinder's tool rest so the wheel face aligns with the guide slot, then use the included table to set the overhang for the correct point angle before tightening.

Which part of the 825 sharpener will wear out first and need replacement?

The grinding wheel on your bench grinder wears down with use; the 825 attachment itself has no consumable components, so only the wheel requires periodic replacement.

What is the largest drill bit the 825 can sharpen before it hits its capacity limit?

The attachment accepts bits up to 19.00 mm (3/4 in) diameter; larger drills exceed the guide range and cannot be sharpened accurately.
