Broach Cutting Set
A duMont broach cutter Precision Set 00.
There are 15 different combinations for making small keyways & bores.
Set consists of three broaches that cut 1/16", 3/32" & ⅛" wide key ways &
five, Type A collared bushings for ¼", 5/16", ⅜", 7/16" & ½″ diameter holes.
The L-shaped shim is inserted after the first pass to increase the depth-of-cut.
Use plenty of cutting fluid & remove all chips after each pass.
Broach Holder & Shim
An adapter was made to hold the broach cutter to prevent breakage.
The holder has four, shank-gripping set screws (like a 4-jaw chuck).
A fifth set screw, inside the (smaller) ½" diameter end, limits shank depth &
movement under cutting pressures. I use it in the floor drill press.
Making a 3.25" cross-slide knob for the Jet 9x20 lathe.
Precision reamed 5/16" hole.
Bushing
A 5/16" guide bushing inserted into the hole.
Cutting
A 1/16" broach cutter held in the floor drill press. Use ample amounts of cutting fluid.
Perfect broach-cut 1/16" keyway to match the Taig OEM design.
Handle installed on the improved 9x20 lathe cross slide using extra Taig mill lead screw parts.
