CMT 310.060.41 Dowel Drill 6 x 27 x 57.5mm RH is a solid carbide boring bit from CMT, engineered for clean, precise blind-hole drilling in hardwood, MDF, particle board, veneered panels, and other demanding composites. Built entirely from premium super micrograin carbide sourced from Ceratizit in Luxembourg, this 6mm dowel drill delivers the rigidity and edge retention needed for high-speed boring units and CNC router applications where consistent hole quality and long service intervals matter most. Whether you are drilling dowel joints in cabinet components, processing coated panels on a multi-spindle machine, or running continuous cycles on a CNC boring center, this short-series bit (57.5mm overall length) provides the reliability and bore clarity that furniture and panel processing professionals depend on.

Key Features

• Solid super micrograin carbide (HW) construction - the entire bit is machined from premium Ceratizit carbide, not just the tip, which means there is no brazed joint to fail under load and the tool can be resharpened an almost infinite number of times, maximizing long-term value.
• 2 curved, negatively ground spurs (V2) - the unique spur geometry slices the wood fiber cleanly at the perimeter of the bore before the main cutting edges engage, producing exceptionally clear hole walls with no rough edges or tearout, even in veneered and coated panels.
• Centre-point balanced design - the tip is precisely centred so the bit registers accurately at the start of each plunge, reducing wandering and ensuring repeatable hole placement critical for dowel alignment in furniture assembly.
• Plunge edge extending to the centre of the bit - reduces drilling resistance and increases production speed, allowing faster feed rates and higher throughput on automated boring equipment without sacrificing hole quality.
• Cylindrical head larger than traditional tips - the oversized carbide head is extremely resistant to prolonged use, maintaining bore diameter consistency over extended production runs and between resharpening intervals.
• 2-flute spiral design (Z2) with 27mm cutting height - twin flutes evacuate chips efficiently from blind holes, preventing packing that can cause heat buildup or surface damage, and the 27mm cutting depth accommodates standard dowel lengths used in panel furniture.
• 10 x 27mm parallel shank with driving flat - the standardised shank fits chucks and collets on multi-spindle CNC boring machines and boring centers, with the driving flat preventing slippage under high torque and ensuring positive drive engagement.
• Right-hand (RH) rotation - compatible with the vast majority of industrial boring machines and CNC routing spindles configured for standard clockwise-rotation tooling, simplifying integration into existing setups.
• Rated for extreme sharpening (Extreme sharpening classification) - the solid carbide body holds a precision-ground edge through repeated resharpening cycles, making this bit a long-term tooling investment rather than a disposable item.

Why This Product

• For operations running hardwood, MDF, particle board, or veneered panels through CNC boring centers, the solid micrograin carbide body resists the abrasive wear that quickly degrades steel or carbide-tipped bits, keeping bores clean and on-dimension across long production runs.
• The negatively ground curved spurs and centre-balanced tip work together to eliminate the ragged hole edges and surface chip-out that cause rejects in veneered or pre-finished panel work, reducing rework and material waste.
• Because the bit is a single solid unit of carbide rather than a tipped assembly, it offers extra safety characteristics - there is no tip to separate or delaminate under the centrifugal forces generated by high-speed CNC spindles.
• The 6mm diameter and 57.5mm overall length match the short-series format common in multi-spindle boring heads, allowing direct drop-in replacement without adjusting machine setup or boring head geometry.
