Right-Angle Tungsten Carbide End Mill

This right-angle drill is a tungsten carbide end mill sized at 8x12D with a 4.2 mm cutting diameter. It is made from top-grade tungsten steel for sharpness and durability. The tool is intended for slotting acrylic advertising word light strips and similar moulding tasks. It suits sign-makers and fabricators who need precise grooves for LED strip installation.

Optimised Cutting Parameters

The manufacturer recommends a spindle speed of 22000 rpm with an 8000 machining speed and an 80% feed rate. Selecting the blade diameter to match the adhesive strip size ensures proper fit. These parameters help achieve clean slots in acrylic without excessive wear. Buyers who need different diameters or materials should consider other tooling options.

Questions about this item

When will the 4.2 mm tungsten carbide end mill need replacement?

Replace the cutter once the cutting edges dull or chip; tungsten carbide stays sharp far longer than HSS but will eventually wear in abrasive acrylic.

What sustained-use limit appears first when running at 22000 rpm and 8000 machining speed?

Heat buildup in the acrylic is the first limit; the 80 % feed rate helps, but excessive dwell melts the slot and ruins the light-strip channel.
