FAMAG 1662 TCT CYLINDER BORING SERIES METRIC
Our TCT (tungsten carbide tipped) cylinder boring bits deliver clean, tear-free drillings in hardwoods, coated and plastic-coated chipboards, as well as acrylic, Corian®, GFRP, HPL, polycarbonate, PVC and Trespa® panels. Diameters Ø 8–12 mm feature a full TCT head with spiral; from Ø 50 mm onward they include a 10 mm hex shank for superior torque transfer. Precision diamond-ground on CNC machines ensures exceptional accuracy and long service life. Note: Designed primarily for stationary use.
