Tungsten carbide tapered ball nose end mill with coated finish

YINGHUA

YINGHUA R0.75x15xD3.175x38L HRC55 Tapered Ball Nose End Mill fastener

SKU CH-DBE5-APXQK

Tungsten carbide tapered ball-nose end mill with R0.75 radius, 15 mm flute and 3.175 mm shank for CNC milling

  • Product typeRight-Angle Drills
  • Precise R0.75 radius for fine detailing

  • HRC55 tungsten carbide resists wear
  • 175 mm shank fits compact holders
  • 38 mm overall length suits CNC clearance

Precision Tapered Ball Nose End Mill

The YINGHUA R0.75x15xD3.175x38L is a solid tungsten carbide milling cutter coated for hardness rated at HRC55. It features a 0.75 mm corner radius and a 15 mm cutting length on a 3.175 mm shank. Total length measures 38 mm. The tool is supplied new for CNC machining applications.

Suited For Detailed Contour Work

This cutter suits machinists producing 3D contours, engraving or finishing passes in hardened steels and abrasive alloys where the tapered ball nose geometry reduces tool deflection. Buyers needing larger corner radii, extended reach beyond 100 mm total length or shank diameters other than 3.175 mm should look at alternative tooling.

Consistent Wear Under Continuous Cutting

The tungsten carbide substrate and HRC55 coating maintain edge integrity during prolonged profiling cycles rather than only short engagement bursts. Heat resistance supports steady material removal rates in production runs. Safety notes restrict use to industrial cutting by persons aged 18 and over.

Questions about this item

What shank diameter must my CNC collet or chuck accept to hold this 3.175 mm shank cutter?

The cutter shank is 3.175 mm, so your tool holder or collet must clamp that exact diameter.

Will this HRC55 carbide end mill cut harder materials than the high-speed steel bits I already own?

Yes, the HRC55 tungsten-carbide grade is significantly harder than HSS, allowing it to machine tougher alloys while the older bits wear faster.

How can I verify the R0.75 ball-nose radius is cutting correctly after the first pass?

Measure the finished radius on the workpiece; it should match the 0.75 mm specification with a smooth, continuous surface.
