CMT 4 Flute Dowel Drill for Through Holes - 23/64" x 2-3/4" RH is a precision-engineered, right-hand rotating boring tool built for clean, consistent through-hole dowel boring in panel processing and woodworking applications. Manufactured from HW (tungsten carbide) material, this long-series drill delivers reliable performance in solid wood, chipboard, MDF, HDF, plywood, laminates, and coated panels. With a 9mm diameter, 40mm cutting height, and 70mm total length, it is engineered for multi-spindle CNC boring machines, boring centers, and panel processing equipment where accuracy and throughput matter.

Key Features

• HW (Tungsten Carbide) Construction - carbide hardness maintains a sharp cutting edge through high-volume production runs in abrasive sheet materials like chipboard, MDF, and laminates, reducing downtime from frequent tool changes.
• Through-Hole Geometry with 60 deg. Sharpening Angle - the through-hole point geometry is optimized for boring clean exit holes with minimal tearout on the panel face, producing professional-quality results in coated and laminated panels.
• 2-Tooth Cutting Configuration - dual cutting edges balance material removal rate with cut quality, allowing smooth chip evacuation during through-hole drilling and reducing heat buildup at the cutting zone.
• Long-Series 70mm Total Length - the extended 70mm body and 40mm cutting height accommodate panels across a practical range of thicknesses, making this drill versatile across multiple panel processing setups without retooling.
• 10x20mm Shank - precision-ground shank dimensions ensure secure, concentric seating in multi-spindle boring machine chucks and CNC boring center toolholders, minimizing runout for accurate hole placement.
• Right-Hand (RH) Rotation - designed for standard right-hand spindle rotation found on the vast majority of CNC boring centers and panel processing machines, making it a direct-fit replacement in most production environments.
• 9mm Diameter - matches the standard metric dowel boring diameter used widely in furniture and cabinet production, ensuring compatibility with 8mm and 10mm dowel joinery systems when paired with correctly sized dowels.

Why This Product

• The 40mm cutting height on a 70mm long-series body means this drill handles a broad range of panel thicknesses in a single tool, reducing the need to swap drills when processing boards of varying dimensions on CNC boring lines.
• HW carbide construction makes this drill a practical choice for abrasive engineered wood products like chipboard, MDF, and HDF - materials that quickly dull high-speed steel tooling and cause costly production interruptions.
• The through-hole 60 deg. sharpening geometry is purpose-built for panels where both the entry and exit faces are visible or finished - delivering clean bore walls on both sides without secondary cleanup operations.
• The standard 10x20mm shank and 9mm diameter make this a direct-fit dowel drill for multi-spindle CNC boring machines and boring centers commonly used in cabinet and furniture panel processing, simplifying sourcing and machine compatibility checks.
