HRC70 4-Flute Solid Carbide Square End Mill Overview
This HRC70-series 4-flute solid carbide square end mill is developed for finishing hardened steel and other confirmed high-hardness workpieces. Its TiSiN nano coating, ultra-fine 0.2 μm carbide matrix, reinforced core and strengthened cutting-edge geometry support thermal stability, edge strength and dimensional consistency under controlled hard-milling conditions.

Усовершенствованное нанопокрытие TiSiN
The TiSiN nano coating supports surface hardness and thermal resistance, helping the cutting edge remain stable at elevated cutting temperatures. It is intended for controlled dry or air-assisted finishing of hardened steels and high-hardness alloys.
Ultra-Fine Carbide & Reinforced Core
Optimized Cutting-Edge Geometry
Strengthened Square-End Profile
The edge profile is configured to resist premature chipping under high cutting resistance while supporting flat-bottom features and defined shoulders.
Four-Flute Stability
Four cutting edges and a reinforced core support light side milling and finishing where rigidity and surface consistency are priorities.
Hardened-Steel Finishing Applications
Hardened Die & Mold
Finishing SKD11, D2, DC53, H13 and comparable heat-treated die steels.
Precision Gear Features
Selected induction-hardened gear, spline and wear-resistant component features.
Hardened Structural Parts
Finishing operations requiring controlled surface quality and dimensional consistency.

Hard-Milling Setup Guidance
High-Rigidity Setup
Use a rigid machine, spindle and precision shrink-fit or hydraulic holder.
Short Tool Overhang
Keep extension as short as possible to reduce deflection and vibration.
Light Finishing Engagement
Use conservative radial and axial engagement to reduce edge-chipping risk.
