Wheeler Tool Company has been working for forty years on the unconventional tools to eliminate costly secondary operations.

The Polygon Box (PB) Model was the first developed by Wheeler Tool Company to provide a cost effective solution for boring or turning polygons on conventional machining centers.

Boring 1 1/2" Hex Hole
1" Deep In 2.5 Minutes
Most Sizes Machined In One Cut.


PB-46 Mounted on Turret Lathe

4 3/4" Hex Bored in 27 min.
Vertical Shaper Time 1 hr. 48 min.

Polygon Box (PB) Models have proven track record. Over 500 units fielded since development.

The Wheeler Polygon Box Tool is a cam actuated contouring tool using a single cutting point tool bit.

It was developed to do one of the most difficult jobs found in any machine shop - produce blind concentric hexagon or other polygon holes in an economical manner.

Its use enables the operator of a turret lathe with good spindle, to bore "blind" polygon holes as accurately, and almost as quickly as round holes are bored.

Also, to contour polygon surfaces on shafts, etc. all shapes will be smooth, concentric, with straight sides and sharp corners, but, these are only some of the desirable features of this exciting tool.

Another cost saving feature is its adjustability - 1/8" to 2 5/16" hex parts are made from one cam with PB-23 model. 3 1/2" to 6" hex with PB-46 model. It is only necessary to dial next size either in inches or metric and replace the cutting tool to change from one size to another, and only takes about two minutes.

An inexpensive high speed steel cutting tool is used for all operations and can be reground by the lathe operator.

The Polygon Box Tool consists of a Box type holder for a cutting tool which reciprocates under the control of a rotary cam which is journaled in the box.

The Cam is rotated by the lathe chuck jaw or a driver bolted to the spindle nose and the cam's shape corresponds with the hex, or other polygon being produced.

The cam can be replaced in twenty minutes for changing to other shape polygons.

An adapter plate is bolted to the back of the Polygon Box Tool to suit the lathe turret.

Proven on Toughest Steels - No. 300 Brinell
