Advanced TiAlCrN Nano-Coating
Proprietary PVD-applied TiAlCrN (Titanium Aluminum Chromium Nitride) nanocomposite coating delivers exceptional heat resistance (up to 900°C) and oxidation resistance, significantly reducing friction coefficients. This extends tool life by 3× compared to standard AlTiN coatings when machining hardened steels (HRC 58-62), stainless steels, and nickel alloys.
Nano-layered structure enhances adhesion to the carbide substrate, preventing premature delamination under high-stress conditions.
Ultra-Fine Micrograin Carbide Substrate
Utilizes 0.2–0.5μm micrograin tungsten carbide with 12% cobalt binder, optimized for fracture resistance and edge stability. This eliminates micro-chipping during interrupted cuts in high-hardness applications like die-casting molds or aerospace components.
Anti-Vibration Geometry
Proprietary asymmetric helix (35°/45°) and variable pitch design disrupt harmonic resonance, reducing vibration by 70% in deep-cavity machining (e.g., >16mm pocketing). Combined with chamfered cutting edges, this prevents tool deflection and workpiece chatter.

FAQ
HRC62 End Mills for Hard Milling
Q1: What exactly is an HRC62 End Mill?
A1: An HRC62 End Mill is a solid carbide milling cutter specifically engineered to machine hardened steels and other materials with a Rockwell Hardness of approximately 62 HRC (and often up to 68+ HRC). These tools feature ultra-fine grain carbide substrates, advanced wear-resistant coatings (like AlTiN, AlCrN, or nano-composites), specialized geometries (reduced radial engagement, strong cutting edges), and often undercut necks or variable helix/pitch designs to minimize vibration and withstand the extreme cutting forces involved.
Q2: What are the key machining parameters for HRC62 End Mills?
A2: Successful machining requires conservative parameters focused on tool life and avoiding shock:
Low Cutting Speed (SFM): Typically 100-350 SFM (30-110 m/min).
Low Feed per Tooth (IPT): Usually 0.001"-0.004" (0.025 - 0.10 mm/tooth).
Shallow Depth of Cut (DOC): Axial DOC is often 0.010"-0.060" (0.25 - 1.5 mm) or 0.5xD - 1xD. Radial DOC (stepover) is very low, typically 5-15% of the tool diameter.
Use High-Pressure Coolant (Minimum 1000 psi / 70 bar) or Air Blast: Essential for chip evacuation and preventing thermal cracking.
Q3: What tool life can I realistically expect from an HRC62 End Mill?
A3: Tool life is significantly shorter compared to machining softer materials and is measured in minutes of actual cutting time (often 15-90 minutes is common). Expect gradual flank wear, not sudden failure, under optimal conditions. Life depends critically on: material composition/consistency, rigidity of setup/machine, accuracy of programming (avoiding sharp engagement/disengagement), coolant effectiveness, and adherence to recommended parameters. Monitoring wear and replacing tools before catastrophic failure is crucial.
Q4: Can HRC62 End Mills machine materials softer than 62 HRC?
A4: Yes, they can machine softer materials (e.g., 45-60 HRC steels, pre-hardened steels, titanium, certain superalloys). However, they are not optimized for it. Using them significantly below their hardness range often results in inefficient material removal (lower MRR than a standard end mill), higher costs per part, and potentially reduced tool life due to built-up edge or edge chipping caused by the very hard, brittle substrate in less demanding applications. Use them primarily for their designed hard-milling purpose.
Q5: What are the most common failure modes and how to prevent them?
A5:
Flank Wear: Gradual wear on the flank face. Prevention: Optimize parameters (especially reduce SFM), ensure adequate coolant flow to the cut, use the correct coating.
Chipping/Breakage: Sudden edge loss or tool fracture. Prevention: Eliminate vibration (improve rigidity, reduce radial DOC, use variable geometry), avoid tool deflection (shorter gauge length, proper clamping), prevent shock loads (smooth tool paths, arc-in entries, no sharp disengagement).
Thermal Cracking: Heat-induced cracks perpendicular to the cutting edge. Prevention: Maintain consistent, high-pressure coolant application; avoid interrupted cuts/dry machining; manage SFM.
Edge Build-Up: Material welding to the cutting edge. Prevention: Increase SFM slightly (if possible), ensure effective coolant/lubrication, use sharper edge preps/coatings suited for sticky materials.
