SKU CH-J0N0-DNF9K

Tungsten carbide tapered ball nose cutter with R0.75 radius and 15 mm flute length for CNC milling

  • Product typeRight-Angle Drills
  • HRC55 hardness maintains sharp edges longer
  • Tungsten steel construction resists wear in tough materials
  • 15 mm cutting length handles deep contours
  • R0.75 radius produces smooth 3-D profiles

15° Tapered Ball Nose End Mill R0.75

This HRC55 tungsten steel end mill features a 15° taper and a 0.75 mm ball nose radius for precision CNC milling. The solid carbide construction with coating resists wear during detailed contouring and 3D profiling. It suits machinists producing moulds, dies or intricate components where tight radii are required. Industrial use only; not for persons under 18 years.

Sustained cutting in hardened materials

The coated tungsten carbide substrate maintains edge integrity when feed rates are held constant over long tool paths. Heat buildup is managed by the material hardness rather than intermittent cooling pauses. The 50 mm overall length provides reach without excessive deflection during deep pocket work. Builders needing multiple flutes or a different shank diameter should select another tool.

Questions about this item

How much heat does the HRC55 tapered ball nose end mill generate during continuous CNC milling?

The solid tungsten carbide construction and coating help dissipate heat efficiently during prolonged cutting sessions.

What shank size must my CNC collet or holder accommodate for this R0.75x15xD4x50L cutter?

The tool has a 4 mm shank diameter, so a 4 mm ER collet or compatible holder is required.
