Tungsten carbide tapered ball nose end mill, coated finish, 6 mm shank

YINGHUA

YINGHUA Tapered Ball Nose End Mill R0.25x20.5xD6x50L

SKU CH-BG5T-J57NZ

Tungsten carbide tapered ball nose end mill for CNC milling, coated for wear resistance, with a 0.25 mm radius, 20.5 mm flute length and 50 mm overall length

  • Product typeRight-Angle Drills
  • Tungsten solid carbide construction for durable industrial cutting
  • R0.25 tapered ball nose enables precise CNC engraving
  • 50L shank length provides extended reach in deep cavities
  • Coated surface reduces wear during high-speed milling operations

Tungsten Carbide Tapered Ball Nose End Mill

This solid carbide cutter is coated for wear resistance and precision profiling in CNC milling operations. It suits machinists and fabricators producing contoured surfaces or detailed engraving work. The tapered geometry supports deep-reach profiling without tool interference. Industrial users requiring a durable, single-flute solution for non-ferrous or hardened materials will find it appropriate.

Minimum age restriction applies at eighteen years

The tool is intended solely for industrial cutting and engraving tasks and is not classified as a hazardous article. Its overall length of 50 mm and taper length of 20.5 mm define the maximum reach envelope for any given setup. Users needing longer reach or larger ball radii must select a different specification. The coated tungsten steel construction determines the practical cutting speed and feed limits for each material.

Questions about this item

What does the R0.25 radius mean for the cuts this end mill produces?

The R0.25 radius creates a small ball-nose tip that leaves a 0.5 mm radius on the bottom of each cut, useful for fine 3D contours and smooth finishing passes.

How does the 20.5 mm tapered length affect reach in a CNC machine?

The 20.5 mm tapered section extends from the tip before the 6 mm shank begins, giving extra clearance for deep pockets or angled walls without the shank contacting the workpiece.
