Key Features & Benefits
- ISO TCMT16T308 designation — Standard 60° triangle, 16mm inscribed circle, 3.97mm thick, 0.8mm corner radius — fits any TCMT-pocket holder.
- Positive-rake clearance angle — 7° clearance gives a sharp, free-cutting edge that suits softer materials and lighter lathes.
- Through-hole screw retention — Centre hole takes a clamping screw — tighter location than top-clamp on the same holder geometry.
- Three indexable corners — Three working tips per insert — 30 cutting edges per pack of ten.
- Designed for semi-finishing — Typical depth-of-cut 0.5-2.5mm with feed 0.05-0.25mm/rev on steel.
When to Use This Insert
Choose TCMT16T308 for finishing and semi-finishing turning in steel, stainless and aluminium where your holder accepts TCMT-style positive-rake triangles. The sharp positive geometry is ideal for lighter benchtop lathes that lack the rigidity for negative-rake roughing.
