CMT 306.064.11 Dowel Drill 1/4" x 30 x 55.5mm RH by CMT is a precision-engineered carbide-tipped boring tool built for clean, consistent blind hole drilling in solid wood, chipboard, MDF, laminates, and coated panels. Featuring a right-hand rotation with 2 cutting edges and 2 negatively ground spurs, this 1/4" diameter dowel drill delivers flat-bottomed, smooth-walled bores that are essential in furniture manufacturing, cabinet making, and high-speed CNC panel processing. With an 8x20mm parallel shank and a compact 55.5mm overall length, it is sized for multi-spindle boring machines and CNC boring centers running demanding production cycles.

Key Features

• Super-strength steel construction with HW (carbide) head - combines the structural rigidity of high-grade steel with the hardness of a carbide cutting tip, extending tool life through high-production CNC boring runs without premature wear.
• Precision balanced centre point - keeps the drill on target from the moment of entry, reducing wander and producing accurately positioned holes for tight-tolerance dowel joinery and panel assembly.
• 2 HW precision ground cutting edges (Z2) - hardwearing carbide cutting edges deliver clean, consistent bore walls on each pass, minimizing tearout in demanding materials like laminate and coated panels.
• 2 negatively ground spurs (V2) - score the material perimeter before the main cutting edges engage, producing chip-free entry holes and flat-bottomed blind bores with minimal fiber lifting in chipboard, MDF, and hardwood.
• Right-hand rotation (RH) - matches the standard spindle direction of CNC boring centers and multi-spindle panel processing machines, enabling direct compatibility without adapter reversal.
• 8x20mm parallel shank - a standardized shank size that seats securely in CNC collets and boring machine chucks, maintaining concentricity and reducing runout during high-speed operation.
• 30mm cutting height with 55.5mm overall length - the short-series profile keeps the drill rigid under load, reducing deflection and supporting accurate depth control for repeatable blind holes in production environments.

Why This Product

• The combination of negatively ground spurs and precision-ground HW cutting edges makes this dowel drill well suited for drilling clean blind holes in chipboard, MDF, and laminates where surface quality at the bore entrance directly affects finished panel appearance.
• The hardwearing carbide (HW) head is designed to withstand the continuous cycling demands of CNC boring centers and multi-spindle machines, supporting longer runs between tool changes in high-volume furniture and cabinet manufacturing workflows.
• At 55.5mm overall length with a 30mm cutting height, this short-series format keeps the tool stiff and resistance to deflection - an advantage when drilling to precise depths for dowel connections where bore depth accuracy directly affects joint strength and alignment.
• The 1/4" diameter in the CMT 306 series is a common standard for dowel joinery, making this bit a direct fit for panel processing centers configured around standard dowel sizes used throughout furniture production.
