CMT 310.127.11 Dowel Drill - 1/2" Diameter, 2 Flute, Right-Hand Rotation by CMT is a precision boring tool engineered for clean, accurate blind-hole drilling in panel processing and furniture manufacturing environments. Built on a super-strength steel body with a tungsten carbide (HW) cutting head and a P.T.F.E.-coated spiral, this short-series dowel drill delivers consistent, splinter-free holes in solid wood, chipboard, MDF, laminates, and coated panels. With a 27mm cutting height and 57.5mm total length, it is sized for high-volume multi-spindle and CNC boring applications where repeatability and hole quality are critical.

Key Features

• HW (Tungsten Carbide) Cutting Head with 2 Precision-Ground Edges (Z2) - carbide construction holds a sharp edge longer than standard steel, reducing retooling frequency in high-cycle production runs.
• 2 Negatively Ground Spurs (V2) - score the material perimeter before the main cutters engage, producing clean bore walls and flat-bottom holes with minimal tearout on both faces of coated and laminated panels.
• P.T.F.E.-Coated Spiral Flutes - the orange or black P.T.F.E. coating on the spiral portion resists pitch, resin, and adhesive buildup, keeping chips clearing freely and extending tool service life.
• Precision Balanced Centre Point - the HW centre point self-locates accurately on the workpiece, reducing positioning error and keeping holes on-target without pre-marking or pre-drilling.
• Parallel Shank with Driving Flat and Length Adjusting Screw - the 10x27mm shank seats securely in standard boring machine chucks and multi-spindle heads, with the driving flat and adjusting screw allowing precise depth setting and positive torque transfer.
• 2-Flute Design for Blind Hole Drilling - twin spiral flutes promote efficient chip evacuation in stopped-hole applications, preventing chip packing that can cause overheating or bore distortion.
• Right-Hand (RH) Rotation - compatible with the standard spindle direction of most CNC boring centers, panel processing centers, and multi-spindle boring machines, ensuring straightforward installation without spindle reconfiguration.

Why This Product

• The negatively ground spurs and precision carbide cutting edges work together to produce clean, flat-bottomed blind holes in laminated and coated panels - exactly the hole quality required for dowel joint assembly in cabinet and furniture production.
• The P.T.F.E. spiral coating directly addresses one of the most common causes of drill degradation in production environments: adhesive and resin buildup. Keeping the flutes clear means fewer interruptions and longer intervals between tool changes.
• The 10x27mm parallel shank with driving flat and length adjusting screw is a widely used standard in multi-spindle CNC boring heads and boring centers, making this drill a drop-in fit for most existing setups without adapters or modifications.
• At 57.5mm total length with a 27mm cutting height, this short-series configuration keeps the tool compact and rigid - minimizing deflection and vibration during high-speed boring, which directly supports hole position accuracy across large panel runs.
