Mortising Attachment Kit
INTRODUCTION
The Mortising Attachment converts your Drill Press in to an accurate
mortising machine. It is ideal for drilling square holes for mortise &
tenon joints that are commonly used in furniture, cabinets, sash,
pattern shops and other woodworking plants.
The Mortising Attachment Kit can be installed on most any drill press
with a collar size of: 52.5mm, 55mm, 60mm, or 65mm.

MOUNTING THE CHISEL HOLDER
1. Mount the Chisel Holder (A) onto, or just above the base of the Drill
Press quill, with the holder’s fastening bolt facing outward, away from
the drill press column. For a proper t, a Bushing (C) may be required
to be inserted within the chisel holder’s top collar.
2. Once installed, tighten the nut and bolt on the chisel holder to keep
the attachment from slipping.
MORTISING CHISEL AND BITS
Four sizes of Hollow Chisel Mortising Chisels and Bits (E) are included
with the kit - 1/4”, 5/16”, 3/8” and 1/2”. Use only the correct combi-
nation of the chisels with their corresponding bit. These tools are
supplied factory ground, and MUST be sharpened before use. If either
one is dull, there will be excessive friction with heat build-up, which
will make the drilling operation difcult and damage the tools. Consult
woodworking books or magazine articles on the proper techniques to
putting sharp edges on these items.
No bushings are required to install the drill bit shanks into the chisel
holder’s collar, as they both have the same diameter. The shank of the
chisel will be held by the drill press keyed chuck, just as a normal drill
bit would be held.
INSTALLING THE BIT AND CHISEL
1. Insert the drill bit through the chisel and into the drill press’ keyed
chuck. Hand tighten the chuck only.
2. Insert the chisel into the chisel holder, and secure it in place with
the wing nut. NOTE: Clamp the chisel so that its shoulder is about
1/32” below the bottom of the holder.
3. Push the drill bit up into the drill chuck as far as it will go, and
fasten it in place with the chuck key. The end of the drill bit should be
up against the end of the square chisel.
4. Loosen the wing nut securing the chisel and move the chisel
upward to take up the 1/32” space previously left in Step 2. Tighten
the chisel in place. This method assures that there is proper clearance
between the cutting lips of the drill bit and the points of the chisel.
When in use, the square chisel will cut into the wood, forcing the
cut material inwards. The drill bit then cuts out the center of the hole
and directs the chisel cut material up out of the hole in a single motion.
The Hex Bolts (K) supplied with the Kit are long enough to go through
the hold down bracket, fence, plywood and drill press table. Insert the
hex bolt through the slots in each. Use washers under the hex head
bolt, and under the wing nut to distribute the holding pressure.
MOUNTING ON THE DRILL PRESS TABLE
We recommend installing a 1/2” plywood panel on the drill press table.
It can be held in place by inserting it under the mortising fence. Drill
holes in the plywood to match the slots in the table. The plywood will
prevent damage to the the mortising chisel and drill bit if it should
strike the metal drill press table by accident. It is also a simple way to
increase the size of the drill press table to hold your projects.
ASSEMBLE THE HOLD DOWN BRACKET
1. Insert the Hold Down Rod (D) into the center hole of the Rod Hold-
ing Casting (G), and secure it in place with the Hex Screw. A 4mm Hex
Wrench (I) is supplied for this.
2. Slide the Hold Down Bracket (B) down onto the hold down rod.
The hold down can be adjusted up and down on the rod as needed to
apply slight pressure down onto your work that is being drilled. This
bracket will keep your project held down when the mortising chisel &
bit are released and pulled out of the hole that they were drilling.
INSTALL THE CURVED GUIDE RODS
1. Insert the two Curved Guide Rods (H) into the horizontal holes that
are on either side of the rod holding casting, and secure them in pos-
tion with the supplied wing nuts.
2. The guide rods should be positioned on the front face of your work,
so that they put pressure against the wood and push your project
against the fence.

SET UP
1. Place your workpiece on the drill press table and adjust the table
height so that the mortising chisel & bit are about 1/2” above the work.
2. Determine the depth of the mortise that you want to cut, and set
the drill press depth stop to this distance.
3. Set the fence distance so that the chisel & bit are in the location
that you want for drilling the mortise.
- Mark your workpiece with the exact location of the mortise(s) that
need to be drilled.
- Secure your work in place against the fence with the guide rods,
and also with the hold down bracket.
- Move the fence in or out until the chisel aligns perfectly with the
mortise lines that are marked on your work.
- Secure the fence in position with the two hex bolts that run
through the casting, fence and drill press table.
OPERATON
- Best drill press speeds are between 650 to 1800 RPM.
- Use lower speeds on hardwoods.
- Make sure the chisel is square/parallel to the fence.
- Test drill on scrap stock of the same woods of your
project to set the mortising positions, and drill press speed.
- First cut the outside, ends of the mortise, then make overlapping
cuts between the two to nish the mortise.
- Raise the chisel often to clear chips and prevent clogging.
