CMT 311.070.11 Dowel Drill 7 x 35 x 70mm RH is a precision-engineered, right-hand rotation boring tool built by CMT for high-accuracy blind hole drilling in panel processing and furniture manufacturing. Featuring a 7mm diameter tungsten carbide (HW) cutting head, 35mm cutting height, and a total length of 70mm, this 2-flute dowel drill is designed for consistent, clean-walled bores in chipboard, MDF, solid wood, laminates, and coated panels. The spiral flutes are coated with P.T.F.E. to prevent pitch and resin buildup, while the parallel shank with driving flat and length adjusting screw ensures accurate, repeatable depth setting on multi-spindle boring machines and CNC boring centers.

Key Features

• Tungsten carbide (HW) cutting head with 2 precision-ground cutting edges - delivers long-lasting sharpness and consistent bore quality across high-volume panel drilling without frequent retooling.
• 2 negatively ground spurs (V2 configuration) - score the material cleanly ahead of the cutting edges, producing flat-bottomed blind holes with smooth walls and virtually no tearout on chipboard, MDF, and laminates.
• P.T.F.E.-coated spiral flutes - reduce friction and resist pitch, resin, and adhesive buildup on the tool body, extending service life and maintaining chip evacuation efficiency during continuous boring operations.
• Super-strength steel body with precision balanced centre point - minimizes vibration and runout during high-speed rotation, resulting in accurately placed, on-center holes for tight-fitting dowel joints.
• Parallel shank (10 x 30mm) with driving flat and length adjusting screw - provides positive drive engagement and allows fine-tuned depth adjustment for repeatable blind hole depth across multi-spindle setups.
• Right-hand (RH) rotation, 2-flute design - optimized chip flow and cutting geometry for standard right-hand boring spindles common in furniture panel processing equipment.
• 70mm total length (long series) - accommodates boring in deeper panels or setups requiring extended reach, while the 35mm cutting height provides ample cutting engagement for through and blind hole applications.

Why This Product

• The negatively ground spurs combined with the HW precision-ground cutting edges make this dowel drill a reliable choice for furniture and cabinet makers who need clean, splinter-free entries and exits on finished panel surfaces - eliminating the need for secondary cleanup of bore openings.
• The P.T.F.E. coating on the spiral flutes directly addresses one of the most common issues in panel boring: pitch and glue accumulation that slows cut performance and shortens tool life - keeping the tool running efficiently in production environments where downtime is costly.
• With a 10 x 30mm parallel shank featuring a driving flat and length adjusting screw, this drill is purpose-built for multi-spindle CNC boring machines and panel processing centers where precise, consistent depth is non-negotiable for proper dowel joint alignment.
• At 7mm diameter and 70mm total length, this tool fills a specific requirement in dowel boring setups where a compact yet deep-reaching drill is needed - suitable for standard 7mm dowel connections used widely in flat-pack and assembled furniture production.
