CMT 307.055.11 Dowel Drill - 7/32" x 40 x 67mm Right-Hand by CMT is a precision-engineered boring tool built for blind hole drilling in furniture panels, cabinetry components, and solid wood assemblies. Featuring a tungsten carbide (HW) cutting head mounted on a super-strength steel body, this 7/32" diameter dowel drill delivers clean, flat-bottomed holes suited to dowel joint production on multi-spindle boring machines and CNC panel processing centers. With a right-hand (RH) rotation, 40mm cutting height, and an 8x20mm parallel shank, it is sized and configured for demanding production environments where hole quality and repeatability directly affect finished assembly quality.

Key Features

• HW (Tungsten Carbide) Cutting Head on Super-Strength Steel Body - carbide hardness resists wear during high-volume panel boring, extending tool life between regrinds and reducing downtime in production settings.
• Precision-Balanced Centre Point - keeps the drill centered on entry, producing accurately positioned holes that align correctly for dowel insertion without drift or walk.
• 2 HW Precision-Ground Cutting Edges (Z2) - sharp carbide edges shear material cleanly on each revolution, reducing heat buildup and delivering consistent hole diameter across chipboard, MDF, hardwood, and coated panels.
• 2 Negatively Ground Spurs (V2) - negatively ground spurs score the material perimeter before the cutting edges clear the core, producing crisp, tear-free bore walls and flat bottoms essential for tight-fitting dowel connections.
• 8x20mm Parallel Shank - standardized shank size fits directly into multi-spindle boring machine chucks and CNC boring center collets without adapters, ensuring secure seating and minimal runout.
• 40mm Cutting Height with 67mm Overall Length - medium-body proportions provide adequate boring depth for panel doweling applications while maintaining tool rigidity to prevent deflection during the cut.
• Right-Hand (RH) Rotation - matches the standard spindle direction of conventional multi-spindle boring machines and CNC centers, allowing direct drop-in use without spindle reconfiguration.

Why This Product

• The negatively ground spurs combined with precision-ground carbide cutting edges make this drill a strong choice for coated panels and laminates where surface tearout at the bore entry point would be visible in the finished piece.
• The precision-balanced centre point and HW cutting geometry work together to produce flat-bottomed blind holes - a critical requirement for dowel joints that must seat fully and evenly without rocking.
• At 7/32" diameter with a 40mm cutting height, this tool covers the depth needed for standard furniture dowel connections while the 67mm overall length keeps it compact enough for close-spaced spindle configurations on multi-row boring heads.
• The tungsten carbide (HW) construction is suited to abrasive engineered wood products such as chipboard, MDF, and HDF - materials that rapidly dull high-speed steel tooling - making this drill a practical long-term investment for panel furniture production.
