View Full Version : Need to drill a spanner shaft

31-07-2010, 05:26 PM
Trying to drill a series of 3 or 4 holes in a spanner shaft without any joy :mad:

The spanner is dropped forge steel and the HSS bits have just about scratched the sufacelol
Any ideas to get me out of a pickle?

This spanner is pemanently located under my router table in a manner it will be withdrawn from the collet nut and fed onto the nut when needed but I need to cut/drill a cutout in the shaft for it to go on the arc slide here.....

A carbide bit will drill through a file if you don't mind a few red hot sparks, or you could draw the temper or you could weld a tab on the side then drill that.

This is what I use when I come across a tough job.

This is also the place I get most of my drills, nuts, bolts, washers, in fact lots of things. I doubt if you will find cheaper for such quality, and yes, you can get a thousand screws for a couple of squid. Much cheaper than B&Q.
