•Designed with a 5/8 in. shank to fit Delta products; also fits most brands of mortises and drill press attachments This is from the product overview, so I would say yes.
Yes, you do. These are a part of the 'Delta Mortising Kit'. If you don't have the other pieces or suitable substitute they will be useless. Sound like you need the 'Delta Mortising Kit'.
Looking at my 1/2" chisel and bit I see the chisel machined to 3" from bottom of chisel; so yes IF you have the quill travel.
Mortising Chisels and Bits (Set of 4) For sizes 1/4 in., 5/16 in., 3/8 in. and 1/2 in.
Yes - I use them in mine.
Chisel set comes in nice plastic holder with latch top.
They should work.
It all depends on the length of your chuck. The longer your chuck, the more chisel and bit depth you will get through the attachment. The max depth you can get will be about 1.5 inches on the half inch bit And less with the smaller bits.
Drill press only! Also look at the Delta Mortising Kit to see the other REQUIRED pieces. Sounds like the 'Mortising Kit' is what you need, not just the 'Chisels and Bits'.
yes they are
