The CMT 306.055.11 Dowel Drill is a precision-engineered 7/32" diameter boring tool built for high-speed blind hole drilling in furniture manufacturing, cabinet making, and panel processing applications. Featuring a tungsten carbide (HW) cutting head with 2 precision-ground cutting edges and 2 negatively ground spurs, this right-hand rotation drill delivers clean, accurate bores in solid wood, chipboard, MDF, and laminates - making it a reliable choice for production dowel joinery on CNC boring machines and multi-spindle boring centers.

Key Features

• Super-strength steel body with HW (tungsten carbide) cutting head - combines the toughness of a steel shank with the superior hardness of a carbide tip, delivering long service life even at high CNC production speeds.
• Precision balanced centre point - ensures accurate bore positioning on entry, reducing wander and producing consistently centered holes for tight-fitting dowel connections.
• 2 HW precision-ground cutting edges (Z2) - carbide-tipped cutting geometry maintains sharpness longer than standard high-speed steel, reducing downtime between tool changes in production environments.
• 2 negatively ground spurs (V2) - shear the wood fibers cleanly before the cutting edges remove material, producing smooth bore walls and flat-bottomed blind holes with minimal tearout on coated panels and laminates.
• Right-hand (RH) rotation - compatible with standard right-hand spindle boring machines and CNC boring centers without requiring spindle reversal.
• 8x20mm parallel shank - fits standard boring machine chucks and adapters used in panel processing centers and multi-spindle CNC boring equipment.
• 30mm cutting height with 55.5mm total length (short series profile) - compact overall length suits gang-drilling heads with tight spindle spacing, keeping the tool rigid and reducing deflection during blind hole drilling.

Why This Product

• The HW (tungsten carbide) cutting head resists abrasion when drilling abrasive materials such as chipboard, MDF, HDF, and coated panels - materials that quickly dull lesser tooling - making this drill well suited for high-volume cabinet and furniture production runs.
• The combination of a precision balanced centre point with 2 negatively ground spurs means bore entry is controlled and chip-free exit walls are produced, which matters when drilling through laminates or coated surfaces where tearout is visually unacceptable.
• At 55.5mm total length, this short-series dowel drill fits into confined spindle heads on multi-spindle CNC boring machines and panel processing centers where longer drills simply cannot be used without clearance issues.
• Right-hand rotation and the 8x20mm parallel shank make this drill a direct-fit replacement for standard boring head configurations, minimizing setup time when adding or replacing spindles on existing machines.
