Hi gang,
One of the guys at work asked if I could help repair one of his 3 jaw pullers. The job includes sourcing better quality steel (A2 tool steel) and duplicating 4 pieces and drilling 8 holes, de-burr etc. then a home hardening/tempering effort.
I was drilling the 3rd hole, all was going swimmingly, when all of a sudden the drill bit stopped drilling.
I must have created too much heat.
These are good quality drill bits says I,
I grabbed another bit, slowed down, used more cutting fluid and finished the remaining holes without any more issues.
Inspecting the damaged drill bit, it looks and feels like material was welded on to the bit. There was some pretty blue coloring as well.
I'll let you know how the rest of the operation goes.
I really don't have the time for this but, I just couldn't say no when an opportunity to work with something new came along.
