How to sort this problem out.

[Michael CallaghanParticipant @michaelcallaghan68621]

Hi. Today’s problem. I have come across a snapped 6ba tap stuck in the crosshead. It’s below the surface so nothing to hold on to. What is the best way to remove the remaining part if the tap? I have tried drilling, but no joy. I was wondering if an acid of some sort my work. Any ideas.

if the crosshead is non ferrous use alum mixture you will get it at an asian spice shop if you keep it warm it will speed the process up.

A carbide drill, say 2mm, should shift it. A carbide end mill probably better.

+1 on the carbide drill.

I had to drill out a 3mm tap yesterday.

 

Luckily I’ve got a good stock of carby drills from work……..

2.1 mm drill will take some doing if the top of the break is not flat. Spark eroder even a simple one will do the job. You want to save the part ? Noel.
