The tooth geometry of the Z42 burr allows steel and stainless steel to be machined with perfect surface results. Tool changes and double the acquisition costs are eliminated. 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 Z42 process 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 Z42 faceted toothing also contribute to this. The tool runs smoothly without any rattling or vibrations.
