CMT 309.064.11 Dowel Drill 1/4" x 43 x 70mm RH is a precision-engineered tungsten carbide-tipped boring tool built for professional furniture manufacturing, cabinet making, and panel processing applications. Designed for right-hand rotation, this 1/4" diameter dowel drill delivers clean, flat-bottom blind holes in chipboard, MDF, HDF, solid wood, plywood, laminates, and coated panels. The long-series 70mm overall length accommodates thicker panel stock where deeper boring depth is required, making it a reliable choice for multi-spindle CNC boring machines, boring centers, and panel processing centers. With a super-strength steel body, a PTFE-coated cutter portion, and a precision-balanced HW carbide head, this tool is engineered for consistent, high-volume boring performance in demanding production environments.

Key Features

• Super-strength steel body - provides the structural rigidity needed to withstand the mechanical stresses of high-cycle boring operations, reducing deflection and maintaining hole accuracy over time.
• HW (tungsten carbide) head with precision-balanced centre point - the carbide head starts each bore on center without walking, producing accurately positioned holes critical for dowel joinery alignment in furniture and cabinet assembly.
• 2 precision-ground HW cutting edges (Z2) - carbide-grade cutting geometry delivers consistent sharpness through extended production runs in abrasive materials like MDF, chipboard, and laminates, reducing the frequency of tool changes.
• 2 negatively ground spurs (V2) - the negatively ground spur geometry scores the material perimeter cleanly before the main cutting edges engage, producing smooth bore walls and sharp entry circles with no tearout or rough edges.
• 4 spiral flutes - the four-flute design efficiently evacuates chips and sawdust from the bore during drilling, preventing buildup that could cause overheating or bore quality degradation, especially in deep blind holes.
• PTFE coating on the cutter portion - the black or orange PTFE (polytetrafluoroethylene) coating reduces friction and repels pitch, resin, and adhesive buildup, extending the usable life of the tool between sharpenings.
• Parallel shank 10x20mm with driving flat and length adjusting screw - the driving flat ensures positive engagement in the machine spindle to prevent slipping under load, while the length adjusting screw allows precise depth setting for repeatable blind hole depth across every bore in a production run.
• 43mm cutting height - the long-series cutting depth accommodates thicker panels and deeper blind holes that shorter-series dowel drills cannot reach.
• Right-hand rotation - compatible with standard right-hand CNC boring spindles and multi-spindle boring machines used in furniture and cabinet panel processing.

Why This Product

• The long-series 70mm overall length and 43mm cutting height make this drill the right choice when working with thick panel stock or when standard-length dowel drills fall short of the required boring depth in production cabinetry and furniture applications.
• The combination of negatively ground spurs and precision-ground HW cutting edges produces clean, flat-bottom holes with smooth entry and bore walls - essential for tight-fitting dowel joints and professional-grade panel assembly.
• The PTFE-coated cutter portion actively resists pitch and adhesive buildup, reducing the need for cleaning stops during high-volume runs in chipboard, MDF, and coated panel drilling operations.
• The parallel shank with driving flat and length adjusting screw provides secure spindle engagement and repeatable depth control, supporting consistent blind hole production across multi-spindle boring machines and CNC boring centers.
