Drill perfectly square holes for mortise-and-tenon
joints, hinges and more with Shopsmith’s Hollow
Chisel Mortising Attachment
Several years ago, we discontinued the Hollow
Chisel Mortising Attachment that we had
offered for many years. This was due largely
to the fact that hollow chisel mortising was
fading in popularity ... as more and more
woodworkers were turning to slot mortising
with a router. As is the case, with many things
in life, this trend is now reversing itself as
hollow chisel mortising regains its popularity.
Fortunately, we held onto the tooling for this
once popular accessory and are now able to
bring it back, per your numerous requests.
The principle of this special tool is really
quite simple. Just install your Drill Chuck on
the MARK V spindle. Then, slip the Mortising
Attachment over the outside of the quill on
your MARK V, and tighten it in position with
a single 5/32˝ setscrew. Insert the Mortising
Chisel of your choice (1/4˝, 3/8˝ or 1/2˝) in the
other end of the attachment and tighten the
setscrew. Now, slip the appropriate Mortising
Bit up through the hollow chisel
and secure its shaft in your drill chuck.
The attachment holds the chisel (with
sharp honed edges) and keeps it from rotating,
while the special Mortising Bit inside turns. As

you advance the quill, the rotating bit removes
the majority of the stock while the chisel’s
edges shave the sides of the mortise square
and smooth.
The special Hold-Down attaches to the top
of your MARK V’s rip fence to keep your work-
piece from lifting when the chisel is withdrawn.

Mortising Chisel Honing Stone
Hollow chisel mortising requires a great deal
of downward pressure to shave the sides of
the mortise smooth and true. That’s why it is
extremely important that all four edges of the
hollow chisel be kept as sharp as possible.
This precision-molded stone has been made
specifically for this purpose. The Mortising
Chisel Honing Stone is a 50-degree stone for
your 1/4˝, 3/8˝ and 1/2˝ chisel.
