mortise chisel for cordless drill

[flying haggis]

I can see a lot of on site chippies buying this

Thing is, I couldn't see it being used in that clip. I may well be wrong as I have very limited experience of powered morticers, but that seemed to be showing the big morticing machines cutting the mortices.

you are right i didnt spot that

I have a small Rexon morticer. As good a little machine it is it's a pig to push into oak and the like - you wouldn't have a hope in hell of doing it with a hand held drill.

mortice chisels are relatively inexpensive, and I haven't yet found the gospel that says you cannot hit them with a hammer. Of course they will never fit into a mortice chiselholder

BUT the tiny points will splay as it's hammered in, so a few taps and you have to stone them flush again

Too many taps, the splayed points are gonna lock the mortice bit into the wood.

In my mind, and from past experience, a hand drill is difficult to use enough force to push the mortice chisel into the wood,

Total and utter nonsense
My mortiser has a 28" long solid steel handle for pushing the chisel through the wood. It's just not going to happen with a handheld drill with a little bracket on it.
