I was informed that my drill grinder does not have a 67 1/2* guide for the 135* drill. I do have 70*, and 60*. Which guide would be better to use, 130* point, or 140* point for general material, MS, AL etc?
If a drill needs more than just a clean up I'll split the point first then sharpen the ends until the point meets. If I do the end first then try to split the point with the corner of my grinding wheel it's next to impossible to get it to meet at a point due to the slight radius on the edge of the wheel.
I did maybe two or three hundred drills recently, so I got quite good at it
