CMT 309.110.11 Dowel Drill - 11 x 43 x 70mm Right-Hand is a precision-engineered carbide-tipped boring tool built for clean, accurate blind hole drilling in furniture and cabinet production. Combining a tungsten carbide (HW) cutting head with a PTFE-coated spiral body and a parallel shank design, this right-hand rotating dowel drill delivers flat-bottom bores with smooth walls - making it a reliable choice for dowel joinery in solid wood, chipboard, MDF, and coated panels. The 70mm overall length accommodates thicker panel stock where standard-length drills fall short, while the 43mm cutting height provides adequate depth for demanding through-component boring applications.

Key Features

• HW (Tungsten Carbide) Cutting Head - hard carbide material maintains a sharp edge longer than standard steel, reducing the frequency of tool changes in high-volume boring operations.
• 2 Precision-Ground Carbide Cutting Edges (Z2) - dual cutting edges working together produce a clean, flat-bottomed hole essential for tight-fitting dowel connections in furniture panels.
• 2 Negatively Ground Spurs (V2) - score the perimeter of the bore before the main cutting edges engage, preventing surface tearout and delivering crisp entry points on laminates and coated panels.
• 4 Spiral Flutes - evacuate chips rapidly away from the cutting zone, reducing heat buildup and maintaining bore quality over extended production runs.
• PTFE-Coated Cutter Portion - non-stick coating resists pitch and adhesive buildup on the spiral, extending service intervals and keeping cut quality consistent.
• Precision Balanced Centre Point - keeps the drill on-target from first contact, minimizing wander and ensuring hole placement accuracy in CNC and multi-spindle boring setups.
• Parallel Shank with Driving Flat and Length Adjusting Screw (10 x 20mm) - secure, no-slip shank engagement with straightforward depth adjustment, compatible with standard boring machine chucks and adapters.
• 70mm Total Length - extended body suits thicker panel stock and deep blind-hole requirements where shorter drills cannot reach the required depth.
• Right-Hand Rotation (RH) - matches the standard spindle direction of the vast majority of CNC boring centers and multi-spindle panel processing machines.

Why This Product

• The combination of negatively ground spurs and an HW carbide cutting head means the drill scores cleanly before cutting - a critical advantage when boring laminates and coated panels where surface quality directly affects finished product appearance.
• At 70mm in total length with a 43mm cutting height, this drill handles thicker furniture components and deeper blind holes that standard-series dowel drills cannot accommodate without a separate tool change.
• The PTFE-coated spiral and 4-flute chip evacuation design work together to sustain consistent bore quality through long production cycles - reducing downtime caused by pitch buildup or clogged flutes.
• The 10 x 20mm parallel shank with driving flat and length adjusting screw provides a secure, repeatable setup in multi-spindle boring machines and CNC boring centers, supporting accurate depth control across high-volume panel runs.
