Brad-Point Dowel Drill
CMT 311.060.42 is the exact 6 mm left-hand variant in the 311.41/42 XTREME long-life dowel-drill family. It combines a 35 mm cutting length, 70 mm overall length, 10 × 30 mm parallel shank with driving flat, two cutting edges, two curved negative spurs, two spiral flutes, and an extra-fine micrograin carbide cutting section for blind-hole drilling in solid wood, wood composites, laminates, and plastics.
Main Product Description
CMT 311.060.42 is the exact left-hand 6 mm item in the official 311.41/42 long-life dowel-drill family. The verified variation row specifies a 6 mm diameter, 35 mm cutting length, 70 mm overall length, 10 × 30 mm shank, and LH rotation.
The XTREME design uses a premium extra-fine micrograin carbide cutting and spiral section with a centre point, two cutting edges, two spiral flutes, and two curved negative spurs. The geometry is intended to support accurate blind-hole entry, clean rim formation, chip evacuation, long cutting life, and repeated resharpening.
A parallel shank with driving flat and axial-adjustment screw supports installation in compatible boring-machine chucks and adaptors. CMT identifies the family for solid wood, wood derivatives, chipboard, laminates, MDF, and plastic materials, including use on high-speed boring machines, point-to-point equipment, and CNC routers.
