• Burraway tools suit a variety of machines from manual to CNC – and can even be used in a hand-drill with excellent results.
• They are available in a range of inch and metric sizes ranging from 0.093” (3/32”) to 2 inches or from 2mm to 50mm as standard, and a range of standard sizes for both inch and metric sizes and an assortment of blades are in stock.
• The Burraway tools feature an inexpensive, replaceable cutting blade which adjusts to control the amount of edge break and can be easily replaced within a few seconds.
• A range of cutting-edge geometry options to suit different materials are offered, and as standard, tools are supplied already fitted with a double acting blade. The crowned and polished top surface of the blade will not mar the inside surface of the hole.
• Supporting a simple method for easily adjustable cutting pressure, the corresponding adjustment screws, will match according to the tool as covered by our inch and metric programs.

How Burraway tools work :

1. Upon entry, spring tension holds the 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.
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.
