When Rotary Broaching, a pre-drilled pilot
hole is required. The typical pilot hole should
be pre-drilled for Hexagons 3% larger than
the “across the flats” dimension of the Broach.
For example, if you are using a 1/4” Hexagon
Rotary Broach, the across the flats dimension
is .2525”, therefore your pre-drill dimension
would be about .260”. This may vary
depending upon your application, material
and final product specifications.

Thank you for purchasing our Premier Tool Holder

Instructions for using the Rotary Broach Holder
Hole Preparation

1. Be sure to pre-drill your pilot hole larger than the minor
diameter or across-flat dimension of the broach (see reverse side for chart)
2. The hole should have a chamfer the same size or larger
than the major diameter or sharp corner dimension.
3. There must be room in the bottom of the hole for chips,
cutting fluid, coolant, etc.
4. An under-cut, relief or taper in the bottom of the hole
provides a better point for chips to break free, but is not necessary.

Set-Up
1.
2.
3.
4.

The broach holder should be securely held in the machine.
Lock the broach into the holder using the set screw.
Start with minimum feed rate of .002-.003 IPR and 700-800 RPM.
If you remove the broach from the hole before broaching is
completed, the tool will not hold alignment. It must be aligned
manually or by some mechanical means.
5. Some end-play is built into the tool to allow it to follow the hole.

After Broaching is Complete

1. Chips may be removed using a drill or end-mill if required.

Replacement Bearing Packs Available
