HRC55 4 Flute End Mills 0.6μm Carbide Square End Mill H6 For Steel P20

HRC55 4 Flutes Solid Carbide End Mill Square End Mill For Steel P20

Introduction:

The AMG 4-flute solid carbide end mill is a high-performance CNC cutting tool designed for machining pre-hardened steels like P20 (HRC 28-32) and other tough materials up to HRC55 hardness. Its square-end geometry ensures efficient material removal with excellent precision and surface finish.

Features:

Solid Carbide Construction

High rigidity & wear resistance for long tool life.

Optimized for hard milling (up to HRC55).

4-Flute Design

More cutting edges = higher feed rates & better surface finish than 2/3-flute end mills.

Balanced chip evacuation for steel, stainless steel, and tool steels.

Square End (Flat Bottom)

Ideal for shoulder milling, slotting, and profiling in mold/die applications.

Sharp corners for precise 90° edges in P20, H13, and other tool steels.

Advanced Coating (e.g., AlTiN, TiSiN, or similar)

Heat-resistant coating reduces friction & extends tool life in high-temp machining.

Prevents built-up edge (BUE) when cutting sticky materials like P20.

Optimized for P20 Mold Steel

Excellent performance in injection molds, die-casting, and precision tooling.

Suitable for roughing & finishing in hardened conditions.

High-Speed Machining (HSM) Compatible

Stable cutting performance at high RPMs & feed rates.

Typical Applications:

• • Mold & Die Making (P20, H13, S7, etc.)

  • Aerospace & Automotive Components

  • Hardened Steel Machining (HRC 45-55)

  • Precision CNC Milling in Tool & Die Shops
