CMT 307.070.11 Dowel Drill 7 x 40 x 67mm RH by CMT is a precision-engineered tungsten carbide (HW) boring tool designed for clean, accurate blind-hole drilling in furniture manufacturing, cabinet making, and panel processing applications. Built on a super-strength steel body with a balanced centre point, 2 precision-ground carbide cutting edges, and 2 negatively ground spurs, this right-hand rotation dowel drill delivers flat-bottomed holes with crisp, tear-free bore walls in solid wood, chipboard, MDF, and laminates. The 8 x 20mm parallel shank makes it compatible with multi-spindle CNC boring machines, boring centers, and panel processing equipment.

Key Features

• Super-strength steel body with HW (tungsten carbide) head - combines durability and hardness so the drill maintains a sharp edge longer, reducing the need for frequent tool changes in high-throughput production environments.
• Precision balanced centre point - self-centers on contact with the workpiece surface, producing accurately located holes and eliminating drift that can compromise dowel joint alignment.
• 2 HW precision-ground cutting edges (Z2) - carbide cutting edges shear through dense materials like chipboard, MDF, and coated panels with consistent results and low vibration.
• 2 negatively ground spurs (V2) - score the material perimeter ahead of the main cutting edges to produce clean bore walls and flat-bottomed blind holes with no tearout or ragged edges, even in laminates and coated panels.
• Right-hand (RH) rotation - matches the standard spindle direction of multi-spindle CNC boring machines and panel boring centers, ensuring straightforward, no-adapter installation.
• 8 x 20mm parallel shank - fits directly into standard CNC boring machine chuck collets and multi-spindle heads, providing a secure, concentric grip for precise hole positioning.
• 40mm cutting height - provides sufficient boring depth for dowel pockets and through-panel applications common in flat-pack furniture and cabinet assembly.

Why This Product

• The negatively ground spurs combined with precision carbide cutting edges produce clean, flat-bottomed blind holes in a single pass - eliminating secondary cleanup operations and keeping panel processing lines moving efficiently.
• The 7mm diameter and 40mm cutting height match standard dowel pin specifications used in furniture and cabinet joinery, making this drill a direct fit for common assembly workflows without requiring custom tooling.
• The HW carbide construction on a super-strength steel body means the drill withstands the abrasive demands of chipboard, MDF, and laminate boring far longer than HSS alternatives, lowering cost per hole over production runs.
• The precision balanced centre point reduces runout and hole position error - critical when boring multiple dowel locations across a panel face where misalignment directly affects assembly quality and finish.
