A tungsten solid-carbide coated tapered ball-nose end mill for CNC milling with HRC55 hardness and 120 mm overall length

  • Product typeRight-Angle Drills
  • HRC55 hardness extends tool life in hard materials
  • Tungsten solid carbide resists wear during high-speed milling
  • Coated tapered cone geometry improves chip evacuation
  • 120 mm overall length reaches deep cavities
  • 0 mm ball nose radius suits fine contouring

Tapered Ball Nose End Mill HRC55

This tungsten solid carbide cutter features a coated tapered cone design for CNC milling applications. The HRC55 hardness rating indicates high wear resistance during cutting operations. It serves industrial engraving and precision machining needs across various materials. Not suited for hobbyists without industrial-grade CNC equipment.

12 mm Shank with 70 mm Radius

The shank diameter measures 12 mm while the ball nose radius extends to 70 mm for deep cavity access. Total length reaches 120 mm allowing extended reach in complex geometries. Coated carbide construction maintains edge integrity under high-speed rotation. Users must verify machine compatibility with these specific dimensions before purchase.

Industrial Use Restricted to Adults

Safety documentation specifies this bladed product is not for people under 18 years of age. The item is designated only for industrial cutting and engraving purposes, not as a general-purpose tool. Total length range spans 38 to 100 mm across the product line. Buyers needing shorter reach or different shank sizes must source alternative tooling.
