CMT Four Flute Dowel Drill - 10 x 65 x 105mm Right-Hand by CMT is engineered for precision boring in furniture manufacturing, cabinet making, and panel processing applications. This extra-long four-flute dowel drill delivers clean, flat-bottom blind holes in solid wood, chipboard, MDF, and laminates - making it a go-to tool for dowel joinery on large CNC boring centers and multi-spindle machines. The 105mm overall length provides the reach needed for deep blind-hole drilling where standard-length bits fall short.

Key Features

• HW (Tungsten Carbide) Cutting Head - delivers long-lasting edge retention through demanding production runs in hardwood, softwood, MDF, chipboard, and coated panels, reducing tool change frequency on the shop floor.
• Precision Balanced Centre Point - ensures accurate hole positioning at the start of each bore, eliminating wander and keeping dowel holes aligned for tight, consistent joinery.
• 2 Precision-Ground Cutting Edges (Z2) - produce clean, flat-bottomed blind holes with consistent bore geometry, critical for flush dowel seating and strong panel connections.
• 2 Negatively Ground Spurs (V2) - score the material ahead of the cutting edges, preventing tearout and delivering smooth, chip-free bore walls even in laminates and coated panels.
• 4 Spiral Flutes - evacuate chips rapidly from the cutting zone, preventing clogging during deep blind-hole drilling and reducing heat buildup that can degrade cut quality.
• PTFE Coating on the Cutter Portion - resists pitch and glue buildup on the spiral, keeping the flutes clear during production runs and extending the time between cleanings.
• Super-Strength Steel Body - provides structural rigidity across the full 105mm length, minimizing deflection and maintaining bore straightness even in deep-hole applications.
• Parallel Shank with Driving Flat - 10 x 30mm - provides a positive, non-slip seating in CNC boring center chucks and adapters, ensuring secure tool retention during high-cycle use.
• Length-Adjusting Shank - allows fine-tuning of the boring depth directly at the machine, giving operators precise control over blind hole depth without secondary setups.
• Right-Hand (RH) Rotation - compatible with the standard right-hand spindle direction of CNC boring centers and multi-spindle panel processing machines.

Why This Product

• The 105mm total length makes this drill specifically suited for deep blind-hole boring that standard-length dowel drills cannot reach, without sacrificing bore quality or accuracy.
• The combination of negatively ground spurs and precision-ground carbide cutting edges produces clean entry and flat-bottomed holes in laminates and coated panels - materials that commonly cause tearout with lesser tooling.
• The PTFE-coated spiral and efficient four-flute chip evacuation design help maintain consistent cut quality across extended production runs, reducing downtime for cleaning or tool changes.
• The 10 x 30mm parallel shank with driving flat and length-adjusting feature makes this drill well matched to CNC boring centers and multi-spindle machines, streamlining setup and depth adjustment in high-volume panel drilling environments.
