CMT 307.120.11 Dowel Drill 12 x 40 x 67mm RH by CMT is a precision-engineered boring tool built for dowel hole drilling in solid wood, chipboard, MDF, laminates, and coated panels. Featuring a tungsten carbide (HW) cutting head, 2 precision-ground cutting edges, and 2 negatively ground spurs, this right-hand rotation dowel bit produces clean, flat-bottomed blind holes with minimal tearout - making it a reliable choice for furniture manufacturing, cabinet making, and panel processing applications.

Key Features

• Super-strength steel body with HW (tungsten carbide) head - delivers durability and long service life during high-volume panel boring operations, reducing tool replacement frequency.
• Precision balanced centre point - ensures accurate hole placement and reduces walking or drift at the start of each bore, which is critical for tight-tolerance dowel joinery.
• 2 HW precision-ground cutting edges (Z2) - carbide cutting edges maintain sharpness longer than steel alternatives, producing consistent hole quality across a wide range of engineered wood products.
• 2 negatively ground spurs (V2) - score the perimeter of the hole before the main cutting edges engage, preventing surface tearout and delivering clean bore walls on laminates and coated panels.
• Right-hand (RH) rotation - compatible with standard multi-spindle CNC boring machines and boring centers configured for right-hand tooling, ensuring drop-in compatibility without special setup.
• 8 x 20mm parallel shank - fits standard boring machine chucks and collet holders, allowing quick tooling changeover with secure, concentric grip.

Why This Product

• The negatively ground spurs combined with a precision balanced centre point work together to produce flat-bottomed blind holes with clean walls - exactly what dowel joinery requires for a tight, gap-free fit in furniture and cabinet panels.
• With a 12mm diameter, 40mm cutting height, and 67mm overall length, this bit is sized for panel boring applications that demand adequate boring depth without tool interference in multi-spindle machine heads.
• The HW (tungsten carbide) cutting head is suited to abrasive engineered materials like chipboard, MDF, HDF, and laminates - materials that quickly dull standard high-speed steel bits - helping maintain cut quality over extended production runs.
• Right-hand rotation and a standardized 8 x 20mm shank make this bit a practical fit for CNC boring centers and multi-spindle panel processing machines configured with RH tooling, minimizing compatibility concerns during tooling selection.
