Cogsdill Tool Products, Inc. Burraway Burraway How it works ® 1. Upon entry, spring tension holds the replaceable and adjustable cutting blade in the extended position as it removes the burr on the front of the hole. 2. As the feed load increases, the pre-set spring tension is exceeded and the blade retracts automatically as the tool passes through the workpiece. (The crowned and polished top surface of the blade will n o t mar the inside surface of the hole.) 3. Spring tension again causes the blade to extend as it emerges from the ID of the part; the burr is removed on the back side of the hole on the return stroke. A one-pass solution to your hole-deburring problems! BURRAWAY®tools are available in both inch and metric programs (see tool specifications, pages 6–9). Tools for the inch program feature imperial (inch) hardware (adjusting screw); tools for the metric program have metric screws. Both are available from stock at standard prices. 4 Burraway tools feature an inexpensive, replaceable cutting blade which adjusts to control the amount of edge break.

Blade replacement is easy for tools in nominal sizes from 3.0mm (.118 in.) and larger. When the tension adjustment screw, located in the end of the shank on Type A and B tools, is loosened sufficiently, the open-ended slot allows the blade to slide out freely. The replacement blade is then installed and the tension adjustment screw retightened for the desired amount of spring tension. Back-Acting (BA) For deburring back of hole only. Front-Acting (FA) For deburring front...
