Key Features & Benefits
- Two countersink sizes in one set — 16mm and 21mm cover the most common cap-screw chamfers and deburring jobs without buying multiple tools.
- Indexable TCMT carbide inserts — Rotate to a fresh edge instead of regrinding HSS; consistent chamfer angle every time.
- TiN coating on the inserts — Reduces friction and built-up edge in mild steel and stainless, extending insert life.
- Nickel-plated bodies — Holds up to coolant and humidity better than bare steel countersinks.
- Ten replacement inserts supplied — Plenty of edges to keep the set running before reordering.
When to Use This Set
Choose H-11-374-S10 for production deburring, countersinking cap-screw holes and chamfering on lathes or mills where HSS countersinks chatter or burn out. Ideal for fitter-machinists working in steel and stainless.
