CMT 310.110.12 Dowel Drill - 11 x 27 x 57.5mm Left-Hand Rotation is a precision two-flute carbide-tipped boring tool engineered for blind hole drilling in panel processing, furniture manufacturing, and cabinet making applications. Built on a super-strength steel body with a tungsten carbide (HW) cutting head, this left-hand dowel drill is designed to pair with multi-spindle CNC boring machines and panel processing centers, delivering clean, flat-bottomed holes for reliable dowel joinery in chipboard, MDF, solid wood, laminates, and coated panels. The spiral portion is coated with P.T.F.E. to prevent pitch and adhesive buildup during high-cycle production runs, keeping the tool cutting cleanly without interruption.

Key Features

• Hardened carbide (HW) cutting head with 2 precision-ground cutting edges (Z2) - delivers consistent bore quality across dense materials like MDF, chipboard, and hardwood without premature edge wear.
• 2 negatively ground spurs (V2) - shear the wood fibers at the perimeter of the bore before the main cutting edges engage, producing clean, tear-out-free hole walls and flat bottoms ideal for tight-tolerance dowel connections.
• P.T.F.E.-coated spiral flutes - the non-stick orange or black coating prevents pitch, resin, and glue from bonding to the spiral, reducing friction and extending tool life in production environments.
• Precision balanced centre point - ensures accurate hole positioning on entry, eliminating bit walk and keeping dowel holes aligned for flush panel assembly.
• Parallel shank with driving flat and length adjusting screw (10 x 27mm) - provides a secure, slip-free grip in CNC boring machine chucks and allows fine tuning of cutting depth for consistent blind-hole results.
• Left-hand (LH) rotation - purpose-built for left-hand spindle positions on multi-spindle boring machines, ensuring correct chip evacuation and cutting geometry on LH stations.
• Super-strength steel body - resists flexing and vibration during high-feed drilling, maintaining bore roundness and positional accuracy across long production runs.

Why This Product

• The 11mm diameter and 27mm cutting height are matched to standard dowel connection geometry, making this drill a direct-fit solution for furniture panel boring without modification or adapter changes.
• The combination of negatively ground spurs and a precision carbide cutting head means the bit handles coated panels and laminates cleanly - materials where tearout on entry and exit would cause costly rework or scrap.
• Left-hand rotation is a specific requirement for LH spindle positions on multi-spindle CNC boring centers - using the correct rotational hand prevents cutting-edge reversal, poor chip flow, and surface damage to the workpiece.
• The P.T.F.E. spiral coating reduces the need for frequent cleaning stops in glue-adjacent operations, supporting uninterrupted throughput in cabinet and panel production workflows.
