  • 50 mm overall length provides rigidity across acrylic, PVC, nylon, resin, wood and plywood

YINGHUA Two-Flute Carbide End Mill

This YINGHUA two-flute carbide end mill is designed for CNC engraving and cutting tasks. It suits operators who need a single replacement cutter for detailed work on wood, acrylic, PVC, nylon, resin and plywood. The tool is not intended for buyers who require multi-flute roughing cutters or indexable insert systems. It is sold as a single piece for industrial cutting use only.

Thermals noise and power draw

The solid tungsten steel body conducts heat away from the cutting edges during normal CNC routing. With only two straight flutes, chip evacuation remains steady, reducing friction and keeping the tool within expected temperature ranges. No electrical power is drawn by the cutter itself; load depends entirely on the spindle motor and feed rates selected by the operator.

Behaviour under sustained load

During extended engraving sessions the carbide edges maintain sharpness longer than high-speed steel alternatives, allowing consistent material removal across acrylic, PVC, nylon, resin, wood and plywood. The 28 mm cutting length and 50 mm overall length support deep passes without tool deflection. The cutter is restricted to users aged 18 and over and must be used only for industrial cutting applications.

Questions about this item

How do I install the 4 mm shank end mill in my CNC router without causing run-out?

Insert the 4 mm shank fully into a matching 4 mm collet, tighten the collet nut to the machine manufacturer's torque specification, and verify concentricity with a dial indicator before cutting.

When should I replace the tungsten-steel cutter based on wear?

Replace the tool when the two flutes show visible rounding, chipping, or when cut quality on wood, acrylic, PVC, nylon, resin or plywood deteriorates despite correct feeds and speeds.

What cutting-depth limit appears first during a long engraving job in hardwood?

The 28 mm flute length limits the maximum depth of cut in a single pass; exceeding it risks tool deflection and breakage.
