I just bought a new benchtop mortise machine, Powermatic 701, that did not
come with a set of bits. I have DAGS on mortise bit reviews and mortise
machine bits and afew other combinations and the hits are not relevant. What
i am looking for is advice on the best set of bits for my machine. I would
appreciate any suggestions.
TIA

have one 3/8" AMT mortising chisel that came with my Dad's AMT
mortising attachment, and I would like to sharpen it. As far as I
know, I'm out of luck for purchasing additional chisels, as the AMT
mortising attachment uses 3/4" diameter chisels, and Delta and others
use 5/8" chisels. Thanks in advance!
Fisch makes pretty good chisel/bit sets.
As noted by others, they. like most bench chisels,
don't come honed and ready to go. A fine - safe
sides - needle file will get the cutting parts of
the bit better. Small shaped slip stones will
get them even better - sharp and shiny. For
the chisel, Lee Valley sells a pair of diamond
cones for throat sharpening. They're not
expensive - under $20 as I recall. There is
a much more expensive version that has
a cylinder on the end that regiseters inside
the chisel - keeping the grind square to the
long axis of the chisel. But you need one for
each chisel size and at $60 or so eac . . . .
Hone the outside faces of the chisel(s)
- hard arkansas stone or whatever.
And once that's all done you still need to
set the gap between the bit and the chisel.

Thanks for all the advice. I will likely buy the one from Lee Valley. The
powermatic has a built-in adjuster for the bit to chisel spacing. Once i get
the bit set I'll try this and let the group know my amateur opinion. It also
has a built in come for sharpening the inside edge of the chisel.

Interesting. I had a Delta and it didn't work for sh*t on cherry. I
actually stripped the shear pin on the handle trying to cut a 1/2 inch
mortise. I called Delta technical support and finally returned the
mortiser to Woodworker's Supply for a full refund. None of the people
I spoke to ever suggested that the chisel needed sharpening before
use.
Oh well, I've gotten pretty good at the Drill/Chisel and Router
methods.

Look at the "Upscale" reply above.

I am still using the ones that came with my Delta. With that said buy the
sharpening cone and polish the outsides chisel edges immediately. Like
regular chisels you need to sharpen them first. It will make a WORLD of
difference in performance and effort on your part to plunge the chisel down
into the wood.
