CMT 309.090.11 Dowel Drill - 9 x 43 x 70mm Right-Hand by CMT is a precision-engineered carbide-tipped boring tool built for clean, accurate blind hole drilling in furniture manufacturing, cabinet making, and panel processing applications. Designed for use in multi-spindle CNC boring machines and panel processing centers, this right-hand 9mm dowel drill combines a tungsten carbide (HW) cutting head with a super-strength steel body and a PTFE-coated cutter portion to deliver consistent performance in chipboard, MDF, hardwood, softwood, plywood, and coated laminates. Whether you are drilling dowel connection holes in solid wood panels or boring through coated composite sheet goods, this tool is engineered to produce flat-bottom holes with clean, tearout-free walls on every pass.

Key Features

• HW (Tungsten Carbide) Cutting Head - hard carbide material holds a sharp edge longer than standard steel, reducing redressing frequency and maintaining consistent hole quality across high-volume production runs.
• 2 Precision-Ground Cutting Edges (Z2) - dual carbide edges balanced around the centre point shear material cleanly on entry and through the full cutting depth, producing smooth bore walls in wood-based panels.
• 2 Negatively Ground Spurs (V2) - the negative grind geometry scores the perimeter of the hole before the main cutters engage, preventing surface chipping and tearout on veneered, laminated, and coated panel faces.
• 4 Spiral Flutes - four flutes evacuate chips efficiently from the cutting zone, reducing heat buildup and keeping the bore clean for accurate, repeatable hole depth in blind-hole applications.
• PTFE-Coated Cutter Portion - the black or orange PTFE coating on the spiral resists pitch and adhesive buildup, maintaining free chip flow and extending service intervals between cleanings.
• Super-Strength Steel Body - the steel shank and body resist flex and vibration during high-speed boring, contributing to dimensional accuracy and longer tool life.
• Parallel Shank with Driving Flat and Length Adjusting Screw (10 x 20mm) - the flat on the shank locks the drill positively in the machine collet to prevent rotation under load, while the adjusting screw allows precise depth setting without removing and re-measuring the tool.
• Precision-Balanced Centre Point - the HW centre point self-centres on the work surface on contact, eliminating walking and ensuring bore location accuracy even at high spindle speeds.
• 70mm Overall Length with 43mm Cutting Height - the long-series 70mm body reaches the cutting depth needed for thicker panel stock, while the 43mm cutting height accommodates deeper blind holes than standard-series dowel drills of the same diameter.

Why This Product

• Engineered for clean entry on coated and laminated panels - the 2 negatively ground spurs score the panel surface before the carbide edges cut, so veneered, melamine-faced, and laminate-coated workpieces emerge with crisp, chip-free hole edges rather than torn or lifted surface material.
• Built for multi-spindle and CNC boring equipment - the 10 x 20mm parallel shank with driving flat and length adjusting screw is the standard interface for multi-spindle boring machines and CNC panel processing centers, making this drill a direct-fit tool for production furniture and cabinet shop equipment.
• Long-series design handles thicker panel stock - at 70mm overall length with a 43mm cutting height, this drill reaches blind-hole depths that a standard-series 9mm dowel drill cannot, making it the right choice when panel thickness or machine geometry demands greater tool projection.
• PTFE coating reduces maintenance downtime - the coated cutter portion actively resists the pitch and adhesive resin deposits that accumulate when boring MDF, chipboard, and glue-coated composites, so the tool stays free-cutting longer between cleaning cycles in continuous production environments.
