Recently, cross drilling a 1-1/2" diameter brass rod, with new drills, the drill bits were catching and jamming, dragging the chuck out of the bench drill column. I seem to recall that there were such things as drills ground specifically for brass. Are they still available? Axminster, etc. don't seem to cater.
Alternatively, I have limited ability to regrind some older, now blunt drills, on an Eclipse guide ( I forget the Eclipse number) which has an asymmetric wheel system to adjust the wings of the drill bit. I bought the Eclipse second hand, without instructions, but cannot see any way to adjust the drill profile.
An advice or copy of the instructions would be very welcome.
