Mortising tools for round or rectangular holes
Mortising machines fall into two categories, those that drill round or
square holes. Round holes are produced with a mortising bit such as pictured
below (see Jesada 601-818 Mortise/Tenon Bit). Depending on the application,
many flat bottom drill bits are acceptable for such chores.
A mortising machine basically drills square holes producing a tight hole to accept a squared tenon. Most machines consist of a hollow square (very sharp) chisel with a drill bit rotating in the cavity clearing the bulk of the stock. The bit is positioned a tad below the chisel to clear the hole, while the chisel squares the corners. Mortising machines can be free-standing and self-powered or drill press attachments.
Jesada 601-818 Mortise/Tenon Bit,
a two-flute Mortise/Tenon bit is engineered to deliver clean edges,
flat bottoms, and perfect shoulders on tenons. Cutting edge has a
downward shear angle to produce an ultra-clean mortise with no
frayed or torn edges. Works well in wood or composites and is
compatible with almost any mortising jig.

Mortising Machines
Woodhaven 575 Mortising Table
is the safest and easiest way to do mortise & tenon work. Mounts in
the tables miter slot and includes two stops to set the mortise length.
Stock clamps in the jig and feeds forward, guided by the jig in a
straight line, into the bit until it bottoms out against the router
plate. Next the jig moves left & right against stops to cut the mortise
length desired. Fence can be set at any angle from parallel to the
router plate (edge mortising) to 90º to the router plate (end
mortising). Measures 11-5/8" x 15-3/4" and includes two 500 lb. toggle
clamps that hold stock up to 1-3/4" thick. (2-3/4" thick with optional
1" Riser Kit, two required - one for each clamp.) Lifetime guarantee.
Delta 14-651 Professional 1/2 Hp. Square holes? No problem. Delta's industrial mortiser offers
precision with a 1/2-horsepower motor behind it. A rack-and-pinion
system raises and lowers the head, and the mortising head column
swings 180 degrees for off-table work. Clearly a step up from
Delta's MM300 Shopmaster mortising machine, this one's made with the
professional user in mind and includes an adjustable dovetail way on
the mortising head, a tool and chisel tray, a gas-filled head
stabilizer and multiposition feed lever. There's also a generous
16-3/4-by-13-1/2-inch cast-iron base and 2-15/16-inch tall two-piece
fence totaling 13-5/8 inches in length. Bit and chisel changing is
easy with the chuck key/hex wrench. Of course, we always want to use
new tools right out of the box, and Delta's made sure you can get
started right away with 1/4-, 5/16-, 3/8-, and 1/2-inch chisel and
bit sets.
NOTE: If you are needing a state-of-the-art tilting hollow chisel mortiser (with stand), you gotta see this...
How about a mortise & tenon cutter that operates like
a biscuit joiner? This is a tool whose time has come. Most
woodworkers are familiar with or use a biscuit joiner to bond boards
together. Festool has developed a mortising machine that operates
on the same principal. However in this case, the "biscuit" is a
free floating tenon.
