CMT Two Flute Dowel Drill 12 x 44 x 77mm Left-Hand Rotation is a precision-engineered left-hand (LH) boring tool built for high-speed dowel hole production in furniture manufacturing, cabinet making, and panel processing operations. Featuring a tungsten carbide (HW) cutting head, 2 precision-ground cutting edges, and a PTFE-coated cutter body, this 12mm diameter drill delivers clean, flat-bottom blind holes in chipboard, MDF, solid wood, laminates, and coated panels with minimal tearout and extended tool life. Its parallel shank with driving flat and length-adjusting screw makes it fully compatible with multi-spindle CNC boring machines and panel processing centers that require left-hand rotation tooling.

Key Features

• HW (Tungsten Carbide) Cutting Head - hard carbide construction maintains a sharp cutting edge through high-volume production runs in abrasive materials like MDF, chipboard, and laminates, reducing downtime for tool changes.
• 2 Precision-Ground HW Cutting Edges (Z2) - dual cutting edges balanced around a precision centre point produce consistently round, accurately sized 12mm bore holes critical for tight dowel-joint tolerances in furniture assembly.
• 2 Negatively Ground Spurs (V2) - negatively sharpened spurs score the material perimeter cleanly before the cutters remove the core, eliminating tearout on coated panels, laminates, and veneered surfaces for a professional finish.
• PTFE-Coated Cutter Body - the orange or black PTFE (P.T.F.E.) non-stick coating on the cutter portion prevents pitch and adhesive buildup, keeping the drill running freely and extending the effective service life of the tool.
• Super-Strength Steel Body - the high-strength steel shank and body absorb vibration and resist deflection at boring machine spindle speeds, contributing to hole position accuracy across multi-spindle production runs.
• Parallel Shank with Driving Flat and Length-Adjusting Screw - the 10 x 30mm shank with driving flat provides positive torque transfer without slipping, while the length-adjusting screw allows precise depth setting to machine specific panel thicknesses accurately.
• Left-Hand (LH) Rotation - engineered specifically for left-hand spindle positions on multi-spindle boring machines, ensuring the correct cutting geometry is engaged and chip evacuation is optimized for that rotation direction.
• 44mm Cutting Height / 77mm Total Length - the extended cutting height (44mm) within a compact 77mm overall length allows deep blind holes in thick panels without the shank interfering with the panel surface, supporting versatile boring depth setups.

Why This Product

• Left-hand rotation dowel drills are a specific requirement for the LH spindle positions on multi-spindle boring machines - this drill is purpose-built for that role, so cutting geometry and chip flow work correctly rather than against the rotation direction.
• The combination of negatively ground spurs and a precision-balanced HW centre point means the drill enters the workpiece without wandering and exits the bore wall without chipping - a key advantage when drilling coated or veneered panels where surface appearance is critical.
• A 44mm cutting height in a 77mm total-length tool provides enough depth capacity for drilling blind holes in thick furniture panels and cabinet components without requiring an extended-reach adapter that could introduce runout.
• The PTFE cutter coating and HW carbide construction together address two of the most common causes of premature dowel drill failure - adhesive buildup from glued panels and edge dulling from abrasive engineered wood materials - making this a practical choice for sustained production use.
