| Features | Chipbreaker for machining aluminium alloys. The large top and bottom rake angle makes the cutting edge sharper: cutting is faster and lighter, with effective chip breaking. Tolerance G (ground insert) for greater accuracy. 7° positive insert (shape D, 55° rhombic) with screw clamping: slim tip for profiling and copy turning, external and boring, with low cutting forces. SDQC (107.5°) and SDUC (93°) type toolholders. |
Available INNOT grades
| Grade | ISO | Coating | Composition | Application |
|---|---|---|---|---|
| ITK10 ★ | N | Uncoated | Fine-grain carbide | First-choice grade for turning aluminium alloys. Uncoated carbide with a fine, uniform grain matrix: high transverse rupture strength and good wear resistance. |
| ITK20 | N | Uncoated | Carbide | Universal grade for turning aluminium alloys. Uncoated carbide with excellent wear resistance, better chipping resistance, great versatility and reliability. |
★ Recommended grade for this chipbreaker. Uncoated carbide, with a sharp cutting edge for gummy materials. ISO N = aluminium and non-ferrous metals.
