YINGHUA HRC55 Tapered Ball Nose End Mill

The YINGHUA R0.25x15xD4x50L HRC55 Tapered Ball Nose End Mill is a tungsten solid carbide coated milling cutter designed for CNC machining. It suits professional machinists and industrial workshops requiring precise contouring and engraving capabilities. The cutter features a tapered cone geometry with a ball nose profile for detailed 3D profiling work. This new tool arrives ready for immediate use in compatible machining centres.

Shank compatibility and milling clearance

The cutter offers shank diameter options of 3.175 mm, 4 mm, 6 mm, and 8 mm to match various collet and holder systems. Total length ranges from 38 mm to 100 mm, providing reach for deep cavity milling without interference. The solid carbide construction frees the operator from frequent tool changes when processing abrasive materials. Industrial cutting and engraving applications benefit from the coated tapered cone design.

Sustained cutting performance

The HRC55 hardness rating maintains edge integrity during prolonged CNC milling cycles rather than just short passes. Tungsten steel material resists wear when machining hardened workpieces over extended periods. The coated surface reduces friction buildup that typically degrades uncoated tools during continuous operation. Safety guidelines restrict use to persons aged 18 and over for industrial cutting tasks only.

Questions about this item

What is the 15 mm taper length for on this end mill?

The 15 mm taper length defines the cutting depth reach before the shank contacts the workpiece.

How does the HRC55 carbide handle heat during long CNC runs?

Tungsten carbide at HRC55 hardness resists wear and maintains edge integrity under sustained high-speed milling heat.

Which shank diameter from 3.175 mm, 4 mm, 6 mm, 8 mm matches my collet?

Choose the shank diameter that matches your collet size; the tool is offered in 3.175 mm, 4 mm, 6 mm, and 8 mm options.
