CMT 310.060.21 Dowel Drill 6 x 22 x 57.5mm RH by CMT is a solid carbide boring bit engineered for precision dowel hole drilling in furniture manufacturing, cabinet making, and panel processing applications. Built entirely from premium super-micrograin carbide sourced from Ceratizit, this right-hand rotation drill delivers exceptionally clean, flat-bottomed bores in hardwood, MDF, particle board, plywood, veneered panels, and difficult composite materials. Whether you are running a high-speed multi-spindle boring unit or a CNC router, this 6mm diameter short-series drill is designed to keep up with production demands while maintaining bore quality through an extended service life.

Key Features

• Solid super-micrograin carbide construction (HWM) - the entire bit is made from Ceratizit premium carbide, delivering exceptional wear resistance so you spend less time changing tools and more time producing finished parts.
• Extreme sharpening rating - the solid carbide body supports an almost infinite number of resharpenings, making this bit a long-term investment that reduces overall tooling cost per bore.
• 2 curved, negatively ground spurs (V2) - the unique spur geometry produces exceptionally clean bore walls with no rough edges or tearout, which is critical for furniture joinery where dowel fit and surface quality matter.
• Centre-point balanced tip design - the balanced centre point keeps the drill tracking true from the moment of entry, reducing wander and producing consistently accurate hole placement across high-volume runs.
• Plunge edge extending to the centre of the bit - reduced drilling resistance means faster chip evacuation and higher production speeds, especially on demanding materials like MDF and coated panels.
• Cylindrical head larger than traditional tips - the oversized head geometry is extremely resistant to prolonged use, maintaining dimensional integrity longer between service intervals.
• 2 spiral flutes (Z2) with 2 cutting edges - dual-flute design evacuates chips efficiently during blind hole drilling, keeping bores clean and preventing material buildup that can degrade hole quality.
• 10 x 27mm parallel shank with driving flat and adjustable screw length - the shank design provides positive drive engagement in multi-spindle boring machines and CNC boring centers, preventing slippage under load.
• Right-hand (RH) rotation - compatible with the standard spindle direction of industrial boring machines and CNC routers, making this a direct-fit replacement for common dowel drilling setups.

Why This Product

• Furniture and cabinet shops drilling hundreds of dowel connections per shift need a bit that stays sharp longer - the solid carbide body and extreme sharpening rating mean fewer tool changes and lower cost per hole over the life of the bit.
• Panel processors working with veneered wood, MDF, and coated particle board require tear-free entry and exit - the negatively ground curved spurs deliver the clean bore walls that glue-up and assembly quality depend on.
• CNC router and high-speed boring unit operators benefit from the plunge edge running to the centre of the bit, which actively reduces drilling resistance and supports faster feed rates without sacrificing bore accuracy.
• The solid carbide construction - as a single unit of carbide rather than a tipped design - provides extra safety integrity during high-cycle boring operations where bit failure could interrupt production or damage workpieces.
