CMT 309.060.11 Dowel Drill 6 x 43 x 70mm RH is a precision-engineered boring tool from CMT, designed for drilling clean, flat-bottom blind holes in panel processing and furniture manufacturing applications. Built on a super-strength steel body with a tungsten carbide (HW) cutting head, this right-hand rotation dowel drill delivers consistent results in solid wood, chipboard, MDF, laminates, and coated panels. The 70mm overall length accommodates thicker panel stock, making it well suited for multi-spindle CNC boring machines, boring centers, and panel processing equipment that demand repeatable accuracy across high-volume production runs.

Key Features

• HW (Tungsten Carbide) Cutting Head with Precision-Balanced Centre Point - the hard-wearing carbide material maintains a sharp edge longer than standard steel, while the balanced centre point self-locates on contact, reducing wander and producing accurately positioned holes every time.
• 2 Precision-Ground HW Cutting Edges (Z2) - dual carbide cutting edges slice through wood composite panels cleanly, generating less heat and friction per pass to extend tool service life in continuous production environments.
• 2 Negatively Ground Spurs (V2) - the negative grind geometry scores the material perimeter before the main cutters engage, preventing surface tearout and delivering crisp, clean bore walls on veneered, laminated, or coated panel faces.
• 4 Spiral Flutes - four flutes evacuate chips rapidly and efficiently from the bore, reducing re-cutting of waste material and keeping the hole clean during drilling.
• PTFE-Coated Cutter Portion (Black or Orange) - the polytetrafluoroethylene coating on the spiral reduces pitch and resin adhesion, preventing buildup that would otherwise slow cutting performance or cause the tool to bind in the workpiece.
• Parallel Shank 10 x 20mm with Driving Flat and Length Adjusting Screw - the standardized shank design seats securely in boring machine chucks and multi-spindle heads, while the driving flat prevents rotation slip under load and the adjusting screw allows precise depth setting without additional setup fixtures.
• Right-Hand (RH) Rotation - matches the standard spindle direction of the vast majority of CNC boring centers and multi-spindle machines, ensuring direct compatibility without adapter modification.

Why This Product

• The negatively ground spur geometry combined with the carbide cutting edges makes this drill a strong choice for laminated, veneered, or coated panel surfaces where tearout at the hole entrance would cause visible defects in finished furniture or cabinetry.
• The 43mm cutting height and 70mm overall length provide the reach needed for blind holes in thicker panel stock - applications where a standard short-series dowel drill would bottom out before reaching the required depth.
• The PTFE coating on the spiral actively resists pitch and glue resin accumulation, reducing the frequency of tool cleaning interruptions during sustained production runs on chipboard and MDF panels.
• With a 10 x 20mm parallel shank featuring a driving flat and length adjusting screw, this drill installs directly into standard multi-spindle boring machine heads, eliminating the need for special adapters and simplifying changeover between jobs.
