CMT 310.045.11 Dowel Drill 4.5 x 22 x 57.5mm RH by CMT is a precision-engineered, carbide-tipped boring tool built for blind hole drilling in furniture manufacturing, cabinetmaking, and panel processing applications. Designed with a 2-flute, right-hand rotation cutting geometry and a PTFE-coated spiral body, this short-series dowel drill delivers clean, flat-bottom bores for tight-tolerance dowel joinery in solid wood, MDF, chipboard, laminates, and coated panels. Whether used in multi-spindle CNC boring machines or conventional boring centers, it is engineered to maintain consistent hole quality across high-volume production runs.

Key Features

• Tungsten Carbide (HW) Cutting Head with 2 Precision-Ground Edges (Z2) - hard carbide tipping bonded to a super-strength steel body holds a sharp edge longer in abrasive materials like chipboard, MDF, and laminates, reducing tool change frequency and downtime.
• 2 Negatively Ground Spurs (V2) - score the perimeter of the bore before the main cutters engage, producing clean bore walls and flat-bottom holes free of tearout or rough edges - critical for tight-fitting dowel connections.
• PTFE-Coated Spiral Flutes - the orange or black PTFE coating on the spiral portion resists pitch and adhesive buildup, keeping the flutes clear for smooth chip evacuation and consistent cutting performance over time.
• Precision-Balanced Centre Point - the HW centre point locates the drill accurately at the bore centerline, preventing walking or drift so every hole lands exactly where it should - essential in multi-hole panel layouts.
• Parallel Shank with Driving Flat and Length Adjusting Screw - the 10 x 27mm shank seats securely in machine chucks or multi-spindle heads, and the integrated adjusting screw allows precise depth setting without secondary fixtures.
• Short Series Total Length of 57.5mm - the compact overall length reduces deflection and vibration in high-speed boring applications, contributing to straighter, more consistent holes.
• Right-Hand (RH) Rotation - compatible with the standard spindle direction of conventional boring machines and CNC boring centers, requiring no machine reconfiguration.

Why This Product

• The combination of negatively ground spurs and a precision-balanced carbide centre point means furniture and cabinet makers get clean, accurately located blind holes for dowel connections - without hand-finishing or post-drilling cleanup.
• PTFE coating on the spiral flutes actively resists the resin and adhesive buildup common when boring chipboard, MDF, and coated panels - extending service life and keeping cut quality consistent across long production shifts.
• The 10 x 27mm parallel shank with driving flat and adjusting screw is designed for direct, secure mounting in multi-spindle CNC boring machines and boring centers, making this an easy drop-in tool for production panel drilling operations.
• At a 4.5mm diameter with a 27mm cutting height and 57.5mm total length, this drill is precisely sized for standard dowel boring applications where a short-series tool provides the rigidity needed for accurate, repeatable results in solid wood and engineered panel materials.
