YINGHUA R0.5x60xD8x100L HRC55 Tapered Ball Nose End Mill fastener

SKU CH-GHBJ-6WVV2

HRC55 tungsten carbide tapered ball nose end mill for CNC milling, 60 mm flute length and 100 mm overall length

  • Product typeRight-Angle Drills
  • HRC55 hardness maintains sharp edges during extended CNC milling
  • Tungsten solid carbide construction resists wear in abrasive materials
  • 60 mm cutting length reaches deep cavities in a single pass
  • 5 mm ball nose radius produces smooth 3-D contours
  • 175 mm shank fits standard collets for quick tool changes

Precision CNC milling cutter

This R0.5x60xD8x100L tapered ball nose end mill is made from tungsten solid carbide with a HRC55 hardness coating. It is designed for industrial CNC milling and engraving operations requiring high wear resistance. The cutter suits machine shops and fabricators producing detailed contours in hard materials. It is not for buyers who need a general-purpose drill bit for hand-held use.

Right-angle drill interface limits

The tool fits right-angle drill holders with shank diameters of 3.175 mm, 4 mm, 6 mm or 8 mm and total lengths between 38 mm and 100 mm. Rigidity and reach depend on the selected shank and extension length. Users must match the holder precisely to avoid run-out. It is not for builders who need a standard straight-shank drill chuck.

HRC55 tungsten carbide hardness

The HRC55 rating on tungsten carbide determines whether this cutter withstands the abrasion and heat of your specific workpiece material. Verify that the hardness matches the alloy, composite or hardened steel you are machining. It is not for buyers who require a lower-hardness grade for softer substrates.

Questions about this item

Should I pick the 3.175 mm, 4 mm, 6 mm or 8 mm shank?

Choose the shank that matches your collet or chuck; 3.175 mm fits 1/8" holders, 4 mm and 6 mm are common metric sizes, and 8 mm suits larger CNC spindles.

What does the R0.5 radius do when the cutter is in the spindle?

The 0.5 mm ball radius produces a 1 mm wide rounded bottom, letting you contour 3D surfaces and finish fillets without sharp corners.

How does the HRC55 hardness affect tool life in carbide?

At HRC55 the tungsten carbide resists abrasion during high-speed milling, so the coated tapered cone keeps its edge longer in hardened steels and composites.
