Hello,

Welcome to the world of machining! Put your Big Boy pants on and walk over to the pedistal grinder and grind a .5 corner radius on a 1" daimeter drill. If the world was driven by you youngsters then we would still be using stone wheels and wooden axels.

Good Luck

What is 9310? If it is brass or aluminium use a D bit

I make special tooling. Check my post! If you have any needs email me toolmacker4u@hotmail.com I will quote you a price. If you have the drill i will put a radius on the tip to cut to center 1pcs 80.00 2 pcs 60.00 each. I recommend pre drill first then finish with form drill.
