CMT 306.070.11 Dowel Drill 7 x 30 x 55.5mm RH by CMT is a precision-engineered carbide-tipped boring tool built for fast, accurate blind hole drilling in furniture manufacturing, cabinet making, and panel processing applications. With a 7mm cutting diameter and a right-hand rotation, this dowel drill delivers clean, flat-bottomed holes ideal for dowel joinery and panel assembly in solid wood, chipboard, MDF, and laminated panels at high CNC production speeds.

Key Features

• Super-strength steel body with HW (carbide) head - combines structural rigidity with premium hardness, so the tool resists deflection and holds a sharp edge longer during demanding CNC production runs.
• Precision balanced centre point - locates on the workpiece accurately before the cutting edges engage, reducing wandering and ensuring hole placement is consistent across every panel in a batch.
• 2 HW precision ground cutting edges (Z2) - carbide-tipped geometry removes material cleanly and efficiently, extending service life well beyond standard high-speed steel alternatives.
• 2 negatively ground spurs (V2) - score the material perimeter ahead of the main cutting edges, producing clean bore walls and minimising tear-out on laminates, coated panels, and veneered surfaces.
• 8 x 20mm parallel shank - fits standard CNC boring machine collets and chucks, making setup straightforward on multi-spindle and panel processing equipment.
• Right-hand (RH) rotation - compatible with conventional CNC boring spindles running standard clockwise toolpaths, no special programming required.
• Resharpenable design - the carbide construction supports multiple resharpening cycles, lowering the long-term cost per hole compared to disposable tooling.

Why This Product

• The 7mm cutting diameter matches the most common dowel pin sizing used in furniture and cabinet construction, making this drill a direct, ready-to-run solution for high-volume dowel joinery without adapter modifications.
• Negatively ground spurs combined with precision carbide cutting edges address one of the most common quality issues in panel processing - chip-out and rough bore walls - delivering finished holes that require no secondary cleanup.
• The 30mm cutting height and 55.5mm overall length are optimised for the short-series boring format used across CNC boring centres and multi-spindle machines, fitting standard tool positions without spacers or custom setups.
• HW (carbide) construction paired with a resharpenable profile makes this drill a cost-efficient choice for production environments where tooling longevity and consistent hole quality directly affect output and waste rates.
