How to make a simple jig for grinding drills on your bench grinder

(1/2) > >>

Pete.:
Here's a simple drill point angle jig I made. Gives reasonable results for people like me who haven't done enough drill sharpening to consistantly grind nice points.

All I've done is milled a vee along the side of a block of scrap ally, slightly off-set from center. Then I milled a 2mm step in the block at 59 degrees (half of the 118 point) and milled a corner off at the same angle.



This is how you use it, just hold the drill bit tight in the vee with your fingers and run the stepped edge along your bench grinder tool rest.





The for the secondary relief you just tilt the block and slide the drill forward.





Here is the result - not perfect, but not bad either and drills quite nicely.

Nice jig Pete...on my "tools" to do list!

Fergus OMore:
Might I congratulate you for what is a practical approach to what some people have cherished as their 'Black Art'?

Keep this attitude of using your own simple solutions to effect clearly almost perfect results. You'll go a long way.


Now go out and thank the person who taught you how to think. That was a precious gift to receive and one which you should cherish the most.
