YINGHUA 2 Flute Ball Nose End Mill

The YINGHUA 2 flute spiral ball nose end mill is a tungsten steel cutting tool designed for CNC routing applications. It suits woodworkers and fabricators who need precise profiling and engraving in a single 4x25 mm cutter.

Sustained cutting behaviour

The two-flute spiral geometry evacuates chips efficiently during continuous passes through hardwood, plywood, acrylic, PVC, nylon, resin, fibreglass and marble. Tungsten steel construction maintains edge integrity under prolonged industrial cutting loads without the overheating typical of lighter-duty bits.

Shank and machine compatibility

The 4 mm shank fits standard collets on desktop and benchtop CNC routers used for fine engraving and detail work. Machines requiring larger shank diameters or higher torque for heavy material removal will not accept this cutter.

Questions about this item

Will this 25 mm tungsten steel bit heat up during extended CNC routing in hardwood?

Tungsten steel dissipates heat well; use proper feed rates and coolant to keep temperatures stable during long sessions.

Which collet or chuck size do I need to hold the 4 mm shank on my router?

A 4 mm ER collet or compatible 4 mm chuck is required for secure clamping.

Can this ball nose cutter run on an older CNC machine with lower spindle torque?

The two-flute geometry reduces cutting forces, making it suitable for machines with modest torque.
