CMT 368.060.11 Dowel Drill for Through Holes by CMT is a precision-ground, carbide-tipped boring bit engineered for clean, full-penetration through holes in thick panels and composite sheet goods. With a 6mm (15/64") cutting diameter, 43mm (1 11/16") cutting height, and 70mm (2 3/4") overall length, this long-series through-hole dowel drill is built for production-level panel processing where consistent bore quality and bit longevity are essential. The right-hand rotation and 8x20mm parallel shank make it a direct fit for multi-spindle CNC boring machines, boring centers, and panel processing equipment across solid wood, chipboard, MDF, and laminated panel applications.

Key Features

• Carbide-Tipped (HW/TCT) Construction - tungsten carbide cutting edges bonded to a high-strength steel body deliver extended service life in abrasive materials like chipboard, MDF, and laminates, reducing tool change frequency in production environments.
• Long-Series Through-Hole Geometry - the 43mm cutting height and 70mm overall length are sized specifically for boring full-penetration holes through thick panels, ensuring complete chip evacuation and a clean exit on the back face.
• 2-Flute Design - dual cutting edges balance chip removal efficiency with bore wall smoothness, producing consistent, flat-sided through holes suited for dowel joinery and hardware fitting.
• Right-Hand (RH) Rotation - matches the standard spindle rotation of CNC boring centers and multi-spindle machines, enabling direct installation without adapters or spindle direction adjustments.
• 8x20mm Parallel Shank with Driving Flat - the precisely dimensioned shank provides secure seating in standard boring machine chucks and collet holders, preventing slippage under lateral cutting forces and maintaining bore position accuracy.
• Through-Hole 60 Sharpening Specification - the 60 deg. point geometry is optimized for through-hole drilling, directing cutting forces to produce clean entry and exit faces with minimal tearout in panel materials.

Why This Product

• The long-series cutting height (43mm) addresses the challenge of boring fully through thick panels in a single pass - eliminating the need for two-sided drilling setups and reducing cycle time on panel processing lines.
• HW carbide construction holds a sharp cutting edge significantly longer than HSS alternatives when working through abrasive engineered wood products like chipboard and MDF, lowering per-hole tooling cost over a production run.
• The standardized 8x20mm shank is compatible with the tooling systems found on the multi-spindle boring machines and CNC boring centers most commonly used in cabinet and furniture production, making this bit a drop-in replacement in established workflows.
• The 2-flute geometry and 60 deg. through-hole point angle work together to produce bore walls and exit faces clean enough for visible hardware installation and dowel joinery without secondary finishing operations.
