| E57 geometry - the universal one |
| For moderate machining conditions |
| For cast iron and steel, but also for stainless materials and materials that are difficult-to cut |
| Center insert - Tiger-tec® silver - the cutting tool material for maximum tool life and maximum process reliability when drilling in ISOP and ISOK materials |
| Specially designed for the requirements of a centre insert |
| 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 |
| 13 deg rake |
| 11 deg clearance |
