Composition: PVD TiCN/TiN coated medium-grain carbide with high toughness.
Application: Best suited for machining of steel and stainless steel. This exceptionally tough grade is perfectly suited for metastable machining conditions offering excellent tool life.
Create Solution to calculate Feeds and Speeds
After creating a solution just choose the Feeds & Speeds icon and our system will provide recommendations. You can customize the information by adding your machine and specifications or make adjustments using the sliders.
| WARNING During through-hole operations, a slug or disc is produced as the tool breaks through the workpiece. When the drill is stationary and the workpiece is rotating, this slug may be hurled from the chuck by centrifugal force. Provide adequate shielding to protect bystanders. |
