Miranda Premium Maxx Pro End Mills: High Performance for Hardened Steel, 45-60 HRC

Standard end mills chip out above 45 HRC; the Miranda Premium Maxx Pro series is built for what comes after. Ultra-fine grain carbide, a nano-composite AlTiN-based coating, and variable helix flutes that break up chatter harmonics let you mill hardened D2, H13, SKD11, and P20 directly, up to 60 HRC, hitting Ra 0.2-0.4 micron finishes that skip EDM and polishing on many dies. Choose 4-flute flat or ball nose, on h6 shanks for the near-zero runout hard milling demands, and run light cuts on a rigid 10,000+ RPM machine. Die repair after heat treatment is where these earn their keep. Tool rooms and stamping die shops across Noida-NCR keep them for hard-milling work. Stocked at Sector 9, Noida; WhatsApp for price.

Frequently Asked Questions: Premium Maxx Pro End Mills

Yes. Hard milling with premium carbide end mills like the Maxx Pro series has replaced EDM for many die and mould applications. You can hit surface finishes of Ra 0.2-0.4 microns on hardened steel, often good enough to skip polishing entirely. The key requirements: a rigid high-speed CNC machine (10,000+ RPM), proper toolpath strategies (constant chip load, no full slotting), and correct cutting parameters (high speed, light cuts).
