YINGHUA Right-Angle Drill 6x6D Down4.2 Tungsten Carbide End Mill

Right-Angle Tungsten Carbide End Mill

This right-angle drill bit is built from top-grade tungsten steel for sharp, durable performance in slotting and milling tasks. It suits sign-makers and fabricators cutting channels for adhesive-backed LED light strips in acrylic. The 4.2 mm down-cut geometry helps evacuate chips cleanly while reducing edge chipping on the workpiece surface. One cutter is supplied per pack.

6 mm Diameter with 22,000 rpm Capability

The 6 mm blade diameter matches common strip-light widths, giving enough headroom for standard adhesive channels in a single pass. At the recommended 22,000 rpm spindle speed with an 8,000 mm/min feed rate and 80 % feed override, the tool maintains consistent chip load without overheating. It runs out of capacity when slots exceed the cutter length or when materials harder than acrylic demand reduced speeds.
