With Tiger-tec® Silver, Walter offers a coating technology for indexable inserts that is unique worldwide, recognizable by the designation key "-S" at the end of the grade description - The special aluminium oxide layer with optimized microstructure reduces wear during turning, milling and drilling operations and increases toughness and temperature resistance at the same time. This enables users to achieve significantly higher cutting data.
- Features
| E67 geometry - the special one |
| Special geometry for optimum chip formation |
| For long chipping materials such as St37, stainless materials, materials that are difficult-to cut and aluminum |
| Outer insert - circumference sintered version with corner radius at periphery |
| Circumference fully ground version - wiper insert at periphery provides extremely good surface finish quality |
| Tiger-tec® silver - the cutting tool material for maximum cutting speed and maximum process reliability |
| Outer indexable insert with increased wear resistance thanks to unique aluminum oxide layer, ideal for use as a peripheral cutting edge |
| Tougher than previous Tiger-tec® CVD coatings |
| Optimised residual strength and a combination of toughness and wear resistance make this the first choice for a centre insert |
| Low wear due to extremely smooth rake face |
| 11 deg clearance |
