  • Rigid 4 mm shank for stable CNC milling
  • Coated ball nose resists wear in production
  • Industrial grade for users 18 years and older

Industrial CNC milling cutter

The YINGHUA tapered ball nose end mill is a solid carbide cutting tool manufactured for precision CNC machining. It serves engineers and machinists who require accurate contouring and finishing operations on hardened materials. The HRC55 hardness rating indicates suitability for demanding industrial applications.

Shank compatibility and reach

Available shank diameters of 3.175 mm, 4 mm, 6 mm and 8 mm allow the cutter to fit a range of collets and tool holders without adapters. Total lengths between 38 mm and 100 mm provide flexibility for shallow pockets or deeper cavities. The 20.5 mm cutting length and 1.0 mm ball radius define the tool's reach and corner profile.

Sustained cutting performance

Tungsten steel construction and a protective coating maintain edge integrity during extended production runs. The solid carbide body resists deflection and heat buildup when machining at consistent feed rates. The tool is rated for industrial use only and must not be operated by persons under 18 years of age.

Questions about this item

How long can the 50 mm flute length cut before chip evacuation becomes a problem?

The 50 mm flute length provides deep reach for pocketing, but sustained use requires frequent retraction to clear chips from the narrow flute.

Does the HRC55 tungsten carbide generate excessive heat during continuous CNC milling?

HRC55 tungsten carbide resists wear and heat buildup, yet prolonged heavy cuts still demand coolant or air blast to manage temperature.

Which shank diameter must my tool holder match from the 3.175 mm, 4 mm, 6 mm or 8 mm options?

The cutter is offered with a 3.175 mm, 4 mm, 6 mm or 8 mm shank; select the holder that matches the chosen shank size.
