CMT 306.050.11 Dowel Drill 5 x 30 x 55.5mm RH by CMT is a precision-engineered boring tool built for high-speed blind hole drilling in furniture manufacturing, cabinet making, and panel processing applications. Featuring a tungsten carbide (HW) cutting head with 2 precision-ground cutting edges and 2 negatively ground spurs, this 5mm dowel drill delivers clean, flat-bottomed bores and smooth wall finishes in solid wood, chipboard, MDF, and laminated panels - making it a dependable choice for production-level CNC boring operations where repeatability and hole quality are critical.

Key Features

• HW (Tungsten Carbide) Cutting Head - provides outstanding wear resistance and edge retention, allowing multiple resharpenings and extending tool life in demanding production environments.
• Precision Balanced Centre Point - ensures accurate bore placement on entry, reducing workpiece shift and improving positional repeatability on multi-spindle CNC boring machines.
• 2 Precision-Ground Cutting Edges (Z2) - deliver consistent chip removal and a clean, flat-bottomed hole profile suited to dowel joinery and panel assembly work.
• 2 Negatively Ground Spurs (V2) - score the material cleanly before the main cutting edges engage, preventing tear-out on chipboard, laminates, and coated panels for a finish-ready bore wall.
• Super-Strength Steel Body - supports the carbide head under the high rotational forces of CNC production speeds, reducing vibration and maintaining dimensional accuracy throughout the cut.
• Right-Hand (RH) Rotation - compatible with standard right-hand spindle configurations on CNC boring centers and multi-spindle boring machines without the need for special adapters.
• 8 x 20mm Parallel Shank - fits standard collet chucks and boring head adapters, enabling quick tool changes and secure tool holding in production setups.

Why This Product

• The negatively ground spurs score and sever surface fibers before the cutting edges remove material, directly addressing the common problem of tear-out and chipping on laminated panels and coated boards - delivering a clean bore without secondary finishing steps.
• With a 5mm cutting diameter and 30mm cutting height, this drill is sized precisely for standard dowel connection drilling in furniture and cabinet panel work, where consistent depth and diameter are essential for tight, reliable joint assembly.
• The HW (tungsten carbide) head is resharpening-compatible, meaning worn edges can be reground rather than replaced - reducing ongoing tooling costs in high-volume production settings.
• The precision-balanced centre point combined with the 55.5mm overall length and 8 x 20mm shank geometry makes this drill a direct fit for common CNC boring center tooling systems, simplifying integration into existing machine setups.
