CMT 311.040.11 Dowel Drill 5/32" x 26 x 70mm RH is a precision-engineered, 2-flute carbide-tipped boring tool built for fast, clean blind hole drilling in furniture panels and cabinet components. Manufactured by CMT, this long-series dowel drill features a hardened tungsten carbide (HW) head, PTFE-coated spiral flutes, and a parallel shank with a driving flat - making it a reliable choice for multi-spindle boring machines and CNC boring centers used in high-volume woodworking and panel processing. At 70mm overall length with a 35mm cutting height, it reaches the depths required for through-panel and deep blind-hole dowel joinery in solid wood, chipboard, MDF, and laminates.

Key Features

• Tungsten carbide (HW) head with precision-balanced centre point - delivers accurate hole placement and consistent hole geometry, reducing tearout and rework on finished panel surfaces.
• 2 negatively ground spurs (V2 configuration) - cleanly score the material perimeter before the cutters engage, producing flat-bottomed blind holes with sharp, chip-free edges for tight-fitting dowel joints.
• 2 precision-ground HW cutting edges - carbide construction maintains sharpness through extended production runs in abrasive materials like chipboard, MDF, and coated panels.
• PTFE-coated spiral flutes - the orange or black PTFE coating on the spiral portion resists pitch and adhesive buildup, keeping flutes clear and reducing heat during continuous boring cycles.
• Super-strength steel body - the steel shank and body absorb drilling forces without flexing, maintaining concentricity at high boring machine speeds for repeatable hole quality.
• Parallel shank with driving flat and length adjusting screw - allows secure, slip-free mounting in standard 10mm boring machine spindles and enables precise depth setting without additional tooling.
• Right-hand (RH) rotation - compatible with the vast majority of multi-spindle CNC and manual boring machine configurations used in cabinet and furniture manufacturing.
• Long-series 70mm length with 35mm cutting height - provides the reach needed for deep blind holes and panel drilling applications where a standard-series bit cannot achieve the required bore depth.

Why This Product

• The 5/32" diameter paired with a 35mm cutting height makes this bit specifically suited for blind dowel holes in furniture panels - applications where depth matters as much as diameter for joint strength and alignment.
• The combination of negatively ground carbide spurs and a precision-balanced centre point means the bit self-centers and scores the surface before cutting, which is critical when boring coated, laminated, or veneered panels where surface finish must be preserved.
• PTFE-coated flutes actively shed resin and glue residue during production runs, reducing downtime spent cleaning bits and extending the interval between resharpening cycles in high-throughput cabinet shops.
• The 10x30mm parallel shank with a driving flat and length adjusting screw fits directly into standard boring machine spindles, making this bit a straightforward, no-adapter drop-in for CNC boring centers and multi-spindle panel processing equipment.
