I am an experience woodworking hobbyist, who is trying to make a golf putter head out of aluminum

stock.

When I try to use my grinding wheel (aluminum oxide) to shape the aluminum stock it loads up quickly and I stop. I've heard of exploding wheels.

When I use my woodworking drill press (14") to drill 1/8" holes one inch deep, the drill bit snaps off and the part that is lodged in the aluminum cannot be pulled out. I have lost three drill bits despite frequently withdrawing the drill bit to make sure the flutes do not get loaded up with aluminum or get overheated. Should I be using a lubricant? At what speed should I set my drill press? Mine has speeds ranging from 350 to 3500 rpm.

For what I thought would be an interesting project has become a very frustrating one. Any help would be appreciated.
