Miranda Premium Maxx Pro End Mills — High Performance for Hardened Steel (45-60 HRC)

Standard end mills struggle above 45 HRC — that is where Miranda's Premium Maxx Pro series takes over. Engineered specifically for hardened steel machining up to 60 HRC, these high-performance end mills feature advanced nano-composite coatings, variable helix geometry, and ultra-fine grain carbide substrates that maintain edge integrity at extreme cutting temperatures. Available in 4-flute flat and ball nose configurations, the Maxx Pro series lets you machine hardened die steel, tool steel, and mould steel directly — reducing or eliminating the need for EDM operations. The variable helix design suppresses chatter harmonics, delivering smooth cuts even at aggressive parameters in hard materials. If you are machining D2, H13, SKD11, or similar hardened tool steels and your standard end mills are chipping after 10 minutes, the Maxx Pro series is built for exactly that challenge.
