Precision milling cutter for CNC detail work

This YINGHUA tapered ball nose end mill is a solid tungsten carbide tool designed for CNC milling and engraving. The cutter carries an HRC55 hardness rating and a protective coating. It is sold new and intended for industrial use only.

Suited for machinists needing fine 3D contours

The 0.25 mm corner radius and 15 mm taper length serve detailed finishing passes in metals and plastics. Buyers who need larger radii, longer reach, or shank diameters beyond the listed options should look at other tooling.

Shank diameter determines machine fit

The cutter is offered with a 3.175 mm shank and total lengths from 38 mm to 100 mm; matching this dimension to your collet or holder is the single specification that decides compatibility.

Questions about this item

How do I install the 3.175 mm shank in my CNC collet without runout?

Clean the shank and collet bore, insert the tool until the shank seats fully, then tighten the collet nut to the machine maker's torque spec — overtightening a 3.175 mm shank is the common error that introduces runout.

When will the HRC55 tungsten carbide ball nose need replacement?

Replace the cutter when the R0.25 mm radius shows visible chipping or when flank wear reaches roughly one-third of the 15 mm flute length, whichever appears first during inspection.

What limit appears first during a long 38 mm depth-of-cut pass in hardened steel?

The 15 mm flute length limits chip evacuation, so chips pack and heat builds before the 38 mm overall length is fully engaged.
