Common Questions About the Drill Bit Sharpener
Clear answers to help you sharpen with confidence and avoid mistakes.
Will this work on HSS and cobalt bits?
Yes. The diamond grinding head sharpens high-speed steel and cobalt bits safely, restoring edges without damaging the steel when used as directed.
How long does sharpening take per bit?
Most bits take just a minute or two to resurface. Faster sharpening gets rigs back to work and reduces job downtime significantly.
Is the attachment easy to mount on my electric drill?
Yes. The grinder fits standard drill chucks and installs in seconds, so you can sharpen on the spot without extra tools or a bench grinder.
Will sharpening change drill angle or size?
You control angle with the guide. The tool refines tip geometry for consistent angles while preserving bit diameter for accurate hole sizes.
What maintenance does the sharpener need?
Rinse the diamond head after heavy use and store dry. Minimal care keeps the wear-resistant surface effective for many sharpening cycles.
