CMT 346.060.11 Dowel Drill with Threaded Shank - 6mm (15/64") Diameter, M10 Shank, Right-Hand Rotation is a precision carbide-tipped boring bit engineered for direct mounting to multi-spindle boring machines and CNC panel processing centers. Designed with an M10 threaded shank, this dowel drill eliminates the need for an adapter, allowing fast and secure spindle-to-bit coupling for high-throughput production environments. With a 6mm cutting diameter and flat-bottom boring geometry, it delivers clean, accurate dowel holes in solid wood, chipboard, MDF, and a wide range of engineered wood panels. Whether you are running a cabinet shop boring line or a large-format CNC boring center, this right-hand rotation bit is built to produce consistent, repeatable results across demanding material types.

Key Features

• Carbide-Tipped (HW/TCT) Construction - tungsten carbide cutting edges bonded to a high-strength steel body deliver long service life and maintain sharpness through heavy production cycles in abrasive materials like chipboard and MDF.
• M10 Threaded Shank - screws directly into multi-spindle boring machine spindles without an adapter, saving setup time and reducing runout for more precise bore placement.
• 6mm (15/64") Cutting Diameter - matches standard dowel sizing requirements, ensuring a snug, accurate fit for joinery, shelf pin, and panel assembly applications.
• 43mm Cutting Height - provides sufficient flute length to clear chips efficiently during deep boring passes, reducing heat buildup and keeping the hole clean from entry to exit.
• 2 Spurs / 2 Flute Design - the paired spurs score the wood fiber ahead of the cutting edge, producing clean bore walls and a flat bottom with minimal tearout on face veneers, laminates, and coated panels.
• Right-Hand (RH) Rotation - compatible with standard right-hand spindle configurations on multi-spindle CNC boring machines and boring centers, making it a direct drop-in for the vast majority of production setups.
• 63mm Relative Length - compact overall length keeps the bit rigid during high-speed boring, reducing deflection and improving hole-location accuracy across a full panel.

Why This Product

• The M10 threaded shank mounts directly to compatible spindles with no adapter hardware required - this means faster tooling changes and one fewer potential source of runout on the boring line.
• The 2-spur, 2-flute carbide geometry is specifically designed for the flat-bottom, clean-wall dowel holes required in furniture, cabinet, and panel joinery - not a general-purpose drill bit pressed into service.
• At 6mm diameter with a 43mm cutting height, this bit covers the standard depth and sizing needed for most dowel pin and shelf pin boring applications in solid wood, MDF, chipboard, and coated engineered panels.
• Right-hand rotation and a 63mm overall length make this a practical, no-modification replacement or expansion bit for existing multi-spindle boring machine tooling sets already running RH configurations.
