Mortice chisels

I have recently bought a Record Morticer and have been told that I need to cut the drills down to 1/8th protrusion from the chisel. I have tried doing this with a normal hacksaw but don't seem to be getting very far. Is there any other way of doing this that anyone can tell me of?

Before cutting the Drills make certain on the dimensions. A good start would be to insert the drill in the chuck fully then withdraw it by a small ammoune say between 1/4 and 1/8 of an inch. Then fit the chisel over the drill and see if it will locate and the lock screw hold it in the corect place if it will then I would suggest there is no need to do any cutting. If the chisel does not locate then that should confirn the ammount to trim.

The best way to trim the shaft is with a grinder. Keep a water bath handy as you must keep the shaft cool you dont want to destroy the temper with excessive heat. It is better to trim and try untill you get it correct. Its easier to take a bit more off than try to put it back on.

I hope this helps.
