The CMT 366.050.11 Two Flute Dowel Drill for Through Holes - 5x44x77mm Right Hand is a precision-engineered boring tool built for clean, accurate through-hole drilling in panel processing and furniture manufacturing applications. Crafted by CMT with a tungsten carbide (HW) cutting head and a super-strength steel body, this dowel drill delivers consistent, repeatable hole quality in chipboard, MDF, HDF, solid wood, plywood, laminates, and coated panels. Its right-hand (RH) rotation and parallel shank with driving flat make it compatible with multi-spindle CNC boring machines, CNC boring centers, and panel processing equipment where precise dowel hole placement is critical.

Key Features

• HW (tungsten carbide) cutting head - provides exceptional edge retention and long service life even in abrasive engineered wood materials like MDF and chipboard, reducing downtime for tool changes.
• 2 precision-ground cutting edges (Z2) - twin flute geometry produces clean bore walls with minimal tear-out, keeping hole quality consistent across high-volume panel runs.
• PTFE-coated spiral portion (orange or black) - the non-stick coating resists pitch and adhesive buildup on the flutes, maintaining cutting efficiency and extending the usable life of the drill between sharpenings.
• Precision-balanced centre point (HW head) - ensures the drill locates accurately on the workpiece surface and starts without wandering, resulting in on-target hole placement critical for dowel joint alignment.
• 2 spiral flutes - efficiently evacuate chips from the bore during through-hole drilling, reducing heat buildup and preventing chip packing that could damage the workpiece or the tool.
• Parallel shank (10x26mm) with driving flat and length-adjusting screw - provides a secure, slip-free grip in boring machine chucks and allows precise depth setting, eliminating guesswork during machine setup.
• 44mm cutting height on a 77mm overall length body - the long-series format reaches through thick panels and deep bores where standard-length dowel drills cannot reach, expanding the range of workpieces the tool can handle.
• Right-hand (RH) rotation - matches the standard spindle direction of most CNC boring centers and multi-spindle machines, making this a drop-in fit for common production setups.

Why This Product

• The 77mm overall length and 44mm cutting height make this drill a practical solution for through-hole boring in thick panels where shorter dowel drills fall short - all while maintaining the tight tolerances required for precision dowel joinery.
• The PTFE-coated spiral combined with the HW carbide head directly addresses two of the most common causes of tool wear in panel processing - adhesive buildup and edge degradation - so production runs stay consistent longer before resharpening is needed.
• With a 5mm cutting diameter and precision-balanced centre point, this drill is optimized for the small-diameter through holes used in standard dowel connections, giving furniture and cabinet manufacturers a purpose-built tool rather than a general-purpose alternative.
• The parallel shank with driving flat and length-adjusting screw is designed specifically for professional boring machine setups, offering secure clamping and repeatable depth settings that reduce setup time and scrap rates on production lines.
