10-piece carbide router bit set

This set contains ten single-flute up-spiral cutters with a 4 mm shank, 22 mm cutting length and 45 mm overall length. They are made from tungsten-cobalt alloy and designed for CNC milling of acrylic, PVC, plastic, wood, multilayer board, plywood and MDF where a high surface finish is required.

Upgrade from multi-flute or down-cut bits

Switching to these single-flute up-spiral cutters improves chip evacuation and reduces heat when machining soft or gummy materials at spindle speeds of 20000 to 24000 RPM with feed rates of 1 to 10 m/min. They are not suited for heavy stock removal in hard metals or for applications that demand a down-cut action to hold thin workpieces down.
