drilling weights..what size bit=1 gr

[ReTodd]

Want to drill my 64's to 62's but need to know what size bit. Also, drill the tip or heel?

Weight off heal will raise top rpm, off tip will raise engagement. Not sure on size of bit but you will not do it with standard bit. I would practice with a old weight and masonry bit in a drill press will take a little pressure. Weigh before and after on a gram scale.

Google the specific gravity of steel, and compute the volume for a 1/4" hole. I calculated it before but forgot the numbers its around 5/16" I think.

why don't you just go buy some 62's or an adjustable weight?

 

[the fix-it guy]

I think buying the weights would be cheaper than buying several drill bits, unless you got better bits than I got.

2 other ways-hit the side of the weight on an edge sander or belt sander or draw a line on the back w/ a sharpie and grind to the line both ways be patient and weigh often

Just take a little off the bottom of the weights. measure often like said before and keep them uniform

Good luck drilling, hardened steel does not like to be drilled. Grind to desired weight. You can grind the far tip or the easiest is to grind the entire side evenly. Good luck.
