Tungsten carbide tapered ball nose end mill, 3.175 mm shank, 38 mm length

YINGHUA

YINGHUA R1.0x15xD3.175x38L HRC55 Tapered Ball Nose End Mill fastener

SKU CH-25ZG-V56JE

Tungsten carbide tapered ball nose end mill with R1.0 radius, 15 mm flute and 3.175 mm shank for CNC milling

  • Product typeRight-Angle Drills
  • HRC55 hardness keeps edges sharp for clean cuts
  • 0 mm ball radius produces fine surface detail
  • 15 mm flute length reaches deep profiles
  • 175 mm shank suits standard micro collets
  • Tungsten carbide body resists wear in abrasive materials

Precision CNC milling cutter

The YINGHUA tapered ball nose end mill is a solid tungsten carbide tool coated for hardness rated at HRC 55. It is built for CNC milling operations that require precise contouring and finishing in metals and composites. The 1.0 mm radius tip and 15 mm taper angle suit detailed 3D profiling work.

Users needing fine detail in hard materials

Machinists and engineers cutting hardened steel, mould cavities or intricate engravings will benefit from the coated carbide substrate and tapered geometry. The cutter is not intended for hand-held drilling, soft-wood routing or high-volume production where indexable inserts are preferred. Buyers who need a larger corner radius or a straight flute profile should look elsewhere.

1.0 mm ball nose radius decides fit

The 1.0 mm radius at the tip determines the smallest internal fillet and the achievable surface finish on contoured surfaces. Select this tool only when the part design calls for that specific radius; a different radius will not produce the required geometry.

Questions about this item

Which shank diameter should I pick for my collet — 3.175 mm, 4 mm, 6 mm or 8 mm?

Choose the shank that matches your collet or tool holder exactly; the cutter is offered in 3.175 mm, 4 mm, 6 mm and 8 mm diameters.

What does the R1.0 radius and 15 mm taper length mean for my toolpaths?

R1.0 gives a 2 mm ball-nose profile and the 15 mm taper section controls the clearance angle for deep 3-D contouring.

How does the HRC55 carbide grade limit cutting parameters in practice?

HRC55 tungsten carbide handles high feed rates in hardened steels up to about 55 HRC but requires rigid setups to avoid chipping.
