The razor-sharp cutting edges of the Z9 Alu burr produce an impressively high chip volume on soft-grade aluminium and alloys. The large chip cross section provides for fast, efficient working and a high chip volume. Even with the most extreme applications, only in exceptional cases does the Z9 Alu cause cutting edge chipping, yet still with a high chip volume and an optimised cutting angle. The faceted toothing of this burr makes all this possible. The high-quality steel shank of the burr fits perfectly in the power tool. Jamming, slippage or even shaft breakage are a thing of the past. Thanks to its special chip breakers which create short chips, the tool requires little effort and the machine wear is low. The durable sharp cutting edges of the Z9 Alu faceted toothing also contribute to this. The tool runs smoothly without any rattling or vibrations.
