Perfect for all materials and long-lasting performance!


CMT announces the new series of solid carbide boring bits, now available from their extensive industrial line. These bits are entirely made of premium quality super micrograin carbide from Ceratizit in Luxemburg. The entire series offers several design features:


-The unique tip has curved, negatively ground spurs to produce exceptionally clear bores with no rough -edges. Centre point balanced.
-The cylindrical head is bigger than traditional tips and is extremely resistant to prolonged use.
-The plunge edge runs all the way to the centre of the bit to reduce drilling resistance and increase production speed. It lasts longer between sharpenings.
-The solid carbide construction guarantees an almost infinite number of resharpenings, and since it is a solid unit of carbide, it offers extra safety features.
-Ideal for hardwood and difficult composites such as particle boards, MDF and veneered wood.
-Excellent performance on high-speed boring units and CNC routers.


-Premium quality super-strength steel.
-Spiral portion coated with orange or black P.T.F.E.
-Extra-fine micrograin carbide spiral portion with centre point.
-HW head with precision balanced centre point.
-2 precision ground cutting edges (Z2).
-Double angle.
-2 spiral flutes.
-Parallel shank with driving flat and adjustable screw length.
Used for drilling through holes in solid wood, wood composites, plastic and laminated materials on boring machines and dowel drilling devices.

For panels with maximum 30mm in thickness.
