CMT 346.050.11 Dowel Drill with Threaded Shank - 5mm (13/64") Diameter, M10 Shank, Right-Hand Rotation is a precision carbide-tipped boring bit engineered for direct mounting on multi-spindle boring machines. With its M10 threaded shank, this 2-flute dowel drill eliminates the need for an adapter, delivering clean, flat-bottom holes in solid wood, chipboard, MDF, and coated panel materials. The right-hand rotation and precision-ground spurs make it a reliable choice for high-throughput panel processing and furniture manufacturing applications.

Key Features

• M10 Threaded Shank for Direct Mounting - threads directly onto compatible multi-spindle boring machine spindles without an adapter, reducing setup time and improving concentricity for more accurate bore placement.
• Hardmetal (HW) Carbide Cutting Material - tungsten carbide construction maintains a sharp cutting edge over extended production runs, reducing downtime and replacement frequency compared to standard high-speed steel bits.
• 2 Precision-Ground Spurs - cleanly score the perimeter of each hole before the main cutting action begins, producing sharp, tearout-free bore walls in hardwood, softwood, chipboard, MDF, and laminated panels.
• 2-Flute Design with 43mm Cutting Height - the dual-flute geometry efficiently clears chips during the boring stroke, reducing heat buildup and keeping cuts smooth across production quantities.
• Right-Hand (RH) Rotation - matches the standard spindle direction of most multi-spindle CNC boring centers and panel processing machines, ensuring correct engagement right out of the box.
• 63mm Relative Length - provides adequate reach for through-boring and deep dowel pocket applications in standard panel thicknesses without excessive overhang or flex.

Why This Product

• The M10 threaded shank allows direct spindle engagement on compatible multi-spindle boring machines - no adapter required - which means faster changeovers and a more rigid tool-to-spindle connection for consistent hole-to-hole accuracy across an entire panel.
• At 5mm diameter with a 43mm cutting height, this bit is sized specifically for standard dowel joinery work in furniture and cabinet panel production, covering the most common dowel pocket depth requirements in a single pass.
• The hardmetal carbide cutting edges hold their geometry longer in abrasive materials like chipboard, MDF, and HDF - materials that rapidly wear softer tooling - making this bit a cost-effective option for repetitive production boring.
• With 2 spurs and 2 flutes working together, the bit scores before cutting and clears chips efficiently, producing clean entry and exit surfaces on laminates and coated panels where edge quality directly affects finished product appearance.
