CMT 311.020.21 Dowel Drill - 2 x 12 x 70mm Right-Hand is a solid carbide boring bit engineered for precise, clean-bore dowel drilling in furniture manufacturing, cabinet making, and panel processing applications. Built entirely from premium super-micrograin carbide sourced from Luxembourg, this right-hand rotation drill delivers exceptionally smooth blind holes with flat bottoms and no rough edges - making it a dependable choice for high-volume CNC boring operations and multi-spindle boring machines. Whether you are drilling into hardwood, MDF, particle board, or veneered composites, this bit is designed to maintain accuracy and edge integrity across extended production runs.

Key Features

• Solid super-micrograin carbide construction (HWM) - provides outstanding wear resistance and allows an almost infinite number of resharpenings, significantly reducing long-term tooling cost compared to conventional bits.
• Curved, negatively ground spurs (2 spurs, V2) - produce exceptionally clean bore walls and flat-bottom holes with no rough edges or tearout, ensuring dowel joints seat accurately without secondary cleanup.
• Centre point balanced tip design - keeps the drill on-target from the moment it contacts the workpiece, reducing wandering and improving positional accuracy on CNC boring centers and panel processing equipment.
• Plunge edge extending to centre of bit - reduces drilling resistance and increases production throughput by allowing the bit to enter material more efficiently, particularly in dense composites and hardwoods.
• Cylindrical head larger than traditional tips - offers extended resistance to prolonged use and maintains structural integrity during high-speed boring, keeping performance consistent across long production cycles.
• 2 cutting edges and 2 spiral flutes (Z2) - work together to evacuate chips efficiently during dowel boring, keeping the cutting zone clear and maintaining consistent hole quality in materials such as chipboard, MDF, and veneered wood.
• 10 x 40mm parallel shank with driving flat - ensures secure, repeatable seating in machine spindles, compatible with multi-spindle CNC boring machines and boring centers that use standard parallel shank tooling.
• Extreme sharpening rating - the solid carbide unit can be resharpened to like-new performance repeatedly, maximizing the usable life of each bit and reducing replacement frequency in demanding production environments.
• Right-hand (RH) rotation - matches the standard spindle direction of most CNC boring centers and multi-spindle panel boring machines, ensuring drop-in compatibility with no spindle modification required.

Why This Product

• For cabinet makers and furniture manufacturers who need clean, precise blind holes for dowel joinery, the curved negatively ground spurs and centre-balanced tip deliver flat-bottom bores free of tearout - eliminating the finishing work that rougher bits leave behind.
• Production shops running high-speed CNC boring units or multi-spindle boring machines benefit from the plunge edge-to-centre design, which reduces cutting resistance and lets the machine bore faster without sacrificing hole quality in MDF, particle board, or hardwood.
• The solid HWM carbide construction supports repeated resharpenings, making this bit a long-term tooling investment rather than a disposable item - ideal for shops processing difficult composites and veneered panels at scale where tool life directly affects per-part cost.
• With a 2mm cutting diameter and 12mm cutting height in a compact 70mm overall length, this bit is purpose-built for the precise, shallow blind boring required by standard dowel connection depths - fitting directly into existing multi-spindle setups without adapters.
