Mortise Chisel Bit 3/8"

Item #
13744
Rating:
80% of 100

The bit removes most of the material, and the chisel squares up the sides, allowing you to cut precise 3/8” mortises for mortise-and-tenon joints. Fits the Jet Benchtop Mortising Machine (#81421, sold separately).

Works well, sharp out of box.
Much improved over the chisels that come with the Jet Mortiser. I will be buying other sizes as the need arises.

I was supprised how sharp it was when new,but after numerous holes it started smoking even when going slow into 4x4 pine legs.

Head of the drill bit was nicked and the tips of the 4 corners were not even. Had a friend sharpen the bit and the chisel and it then worked fine. Bit would fit my 5/8 inch collar on the mortising attachment to my drill press. All the better bits I found required a 3/4 inch collar so I was so of stuck with what I had. OBTW, Rockler's return policy/process is difficult to use.

I purchased a new Powermatic mortiser and this auger bit and square chisel was recommended. I trust Rockler for their choice in products.

I'm a novice woodworker. Can I use a standard drill press with a mortise chisel Bit?
Drummer on Feb 19, 2016
BEST ANSWER: Not without a Mortising attachment
Will this mortising chisel fit a Delta mortising machine?
Philip H on Jan 11, 2016
BEST ANSWER: Will this mortising chisel fit in Delta Model #17-935 mortice kit?
How long is the exposed shaft of the bit above the shank when fully retracted? I have a chisel I can't use with a Delta mortising attachment because the bit shaft is not long enough to reach the teeth of the chuck when fully retracted into the chisel, and I don't need another one of those.
John H on May 20, 2016
Does this bit have the short or the long shank? Want to ensure it will fit a Powermatic mortiser.
Thomas n on Nov 23, 2018
BEST ANSWER: It has the long shaft, it fit my power matic mortiser, very happy with it
What is the diameter of the shank of both chisel and drill? I have an off brand, need to know diameters to know it will fit.
bill f on Jan 19, 2016
BEST ANSWER: Diameter of the bit is 1/4"
Diameter of the Chisel is 5/8"
