Easy and Inexpensive Drill Bit Sharpener

Drill bit sharpener

Can't afford and expensive drill bit sharpener to ensure those angles are accurate?

Don't sharpen enough drills to warrant owning even a cheap sharpener?

Try this simple and inexpensive trick to help you ensure your drill bits have tip on them you can use.


Get two hex headed bolts and nuts and mount them in a piece of off cut steel or timber so that two of their edges are touching (as shown on the right).

Bolts of a suitable construction can be welded together to ensure they don't move.

Sharpen your drill bit carefully using a bench grinder being extra careful not to be too heavy handed.

After only a few moments of grinding remove the drill bit and test against the two hex headed bolts as shown on the right.

After touching up each cutting side of the drill your drill should fit squarely in the angle of the two bolt heads.

The accuracy obviously relies on how close you placed the two bolts together but with this guide it removes the need to eye ball the angle and hope that it's right.



Note: While a bench grinder is suggested an angle grinder firmly held in place can also be used, however Krafty Farm Assistant take no responsibility for the actions of readers. All caution should be taken, all safety gear should be worn and readers are responsible for their own actions.
