CMT 306.090.11 Dowel Drill 9 x 30 x 55.5mm RH by CMT is a precision carbide-tipped boring tool engineered for clean, accurate blind hole drilling in solid wood, chipboard, MDF, laminates, and coated panels. Built for demanding CNC production environments, this right-hand rotation dowel drill delivers consistent bore quality at high spindle speeds, making it a reliable choice for furniture manufacturing, cabinet making, and panel processing operations where dowel joint accuracy is critical.

Key Features

• Super-strength steel body with HW (carbide) head - combines a rigid steel structure with a hard-wearing carbide cutting head, providing the durability needed to sustain high-volume CNC boring cycles without premature wear.
• Precision balanced centre point - ensures the drill enters the workpiece accurately and without wandering, producing consistently centered blind holes that align perfectly for dowel connections.
• 2 HW precision ground cutting edges (Z2) - hardmetal cutting edges maintain sharpness longer than standard steel, reducing downtime between resharpenings and keeping bore quality high across extended production runs.
• 2 negatively ground spurs (V2) - the negative sharpening geometry on the spurs scores the material cleanly before the main cutters remove the core, resulting in clean bore walls, reduced tearout, and flat-bottom holes suited to dowel seating.
• Right-hand rotation (RH) - compatible with the standard spindle direction of CNC boring machines and multi-spindle boring centers, allowing direct installation without adapter modification.
• 8 x 20mm parallel shank - the standardized shank profile provides a secure, repeatable grip in chuck or collet setups, minimizing runout and maximizing concentricity during high-speed boring.
• 9mm cutting diameter x 30mm cutting height - precise dimensional spec ensures the bore matches standard dowel pin sizing, producing tight-fitting joints in furniture and panel assemblies.

Why This Product

• The combination of a precision balanced centre point and negatively ground spurs means cleaner entry and cleaner bore walls - reducing the sanding or cleanup time that rough-boring tools often demand in panel and furniture production.
• The HW (carbide) cutting head holds its edge significantly longer than standard steel alternatives, making this drill well suited to abrasive materials like chipboard, MDF, and coated panels where edge degradation accelerates quickly.
• With a 55.5mm total length and an 8 x 20mm shank, this dowel drill fits the tooling pockets of multi-spindle CNC boring machines and boring centers without requiring non-standard adapters, simplifying setup and changeover.
• The negatively ground spur geometry is specifically suited to man-made boards and laminates where surface quality at the bore opening is critical - delivering the clean, chip-free holes that dowel joint assembly and coated panel work require.
