HRC65 Carbide 4 Flute Square End Mills - Conquer Hardened Steel with Precision & Speed

Dominate the Toughest Materials. Engineered for Performance.

Unlock new levels of productivity and precision in your most demanding machining applications with our premium HRC65 Carbide 4 Flute Square End Mills. Specifically engineered for machining hardened steels, tool steels, and superalloys, these end mills deliver exceptional tool life, superior surface finishes, and unwavering rigidity where standard tools fail.

Unmatched Hardness & Wear Resistance:

• Ultra-High Grade Carbide Substrate: Formulated to withstand the extreme abrasion and high temperatures generated when machining materials hardened up to 65 HRC.

• Optimized Geometry: Advanced flute design and core strengthening ensure maximum rigidity, minimizing deflection and vibration even under heavy radial loads.

• Precision Ground Cutting Edges: Razor-sharp, consistent edges guarantee accurate dimensions and excellent surface finishes, reducing secondary operations.

The Power of 4 Flutes:

• Optimal Material Removal Rate (MRR): The 4-flute design provides the perfect balance for high-efficiency milling in hardened materials, offering more cutting edges than a 2-flute for faster feed rates, while maintaining better chip clearance than higher flute counts.

• Superior Surface Finish: Produces smoother finishes on side walls and floors compared to lower flute counts, ideal for finishing passes and critical tolerances.

• Enhanced Stability: Excellent balance reduces chatter, improving part accuracy and tool life.

Premium Coatings for Peak Performance (Options Available):

• AlCrN (Aluminum Chromium Nitride): Superior oxidation resistance, high hardness, and reduced friction. Excellent all-rounder for most hardened steels under various conditions.

• TiAlN (Titanium Aluminum Nitride): Exceptional heat resistance and hardness, ideal for high-speed applications and dry or near-dry machining.

• Other Advanced Coatings (e.g., ZrN, AlTiN): Available to optimize performance for specific materials or machining strategies.

Key Applications:

• Hardened Steel Machining (45-65 HRC): Dies, molds, punches, tooling, bearings, shafts, gears.

• Tool Steels (H13, D2, A2, M2, etc.): Mold cores/cavities, cutting dies, forming tools.

• Stainless Steels (Precipitation Hardened, Martensitic): Aerospace components, medical instruments, high-strength fasteners.

• Titanium Alloys: Aerospace structural parts, engine components, medical implants.

• Nickel-Based Superalloys (Inconel, Waspaloy, Hastelloy): Turbine blades, exhaust components, high-temp applications.

• High-Speed Machining (HSM) & Hard Milling: Precision contouring, pocketing, slotting, and profiling in demanding materials.

Ideal For:

• Mold & Die Manufacturing: Core/cavity finishing, detail work, insert pockets.

• Aerospace & Defense: Machining critical high-strength components.

• Automotive: Performance parts, tooling, transmission components.

• Medical Device Manufacturing: Precision machining of implants and instruments.

• Energy Sector: Turbine components, valve bodies, drilling equipment parts.

• General Precision Machining: Any job requiring rigidity and longevity in tough materials.
