The CMT 314.060.21 Dowel Drill for Through Holes is a solid carbide boring bit engineered for clean, precise through-hole drilling in a wide range of panel materials. Built from premium super-micrograin carbide, this 6mm diameter drill delivers the edge retention and bore quality demanded by high-production furniture manufacturing, panel processing, and CNC boring operations. Whether you are drilling dowel connection holes in hardwood, MDF, chipboard, or veneered composites, this right-hand rotation bit is designed to perform consistently at high spindle speeds with minimal tearout and maximum tool life.

Key Features

• Solid Carbide (HWM) Construction - the entire body is made from premium super-micrograin carbide from Luxemburg, providing exceptional wear resistance and an almost infinite number of resharpenings, reducing long-term tooling costs significantly.
• Curved, Negatively Ground Spurs at the Tip - the unique tip geometry produces exceptionally clean bore walls with no rough edges or tearout on entry or exit, critical for veneered panels and coated boards where surface quality matters.
• Centre-Point Balanced Design - ensures the bit tracks accurately from the moment of contact, reducing walk and improving hole placement precision on multi-spindle boring units and CNC routers.
• Plunge Edge Running to Centre - reduces drilling resistance and increases production speed, allowing faster feed rates without sacrificing cut quality in demanding production environments.
• 2 Precision-Ground Cutting Edges (Z2) with 2 Spiral Flutes - the dual-edge, double-angle geometry clears chips efficiently and maintains consistent bore quality over extended production runs.
• Cylindrical Head Larger Than Traditional Tips - provides superior rigidity and resistance to deflection during prolonged use, maintaining dimensional accuracy in repetitive through-hole drilling applications.
• 10 x 26mm Parallel Shank with Driving Flat and Adjustable Screw Length - offers secure, consistent seating in standard boring machine chucks and CNC tool holders, reducing slippage during high-speed operation.
• Extreme Sharpening Rating - the solid carbide unit can be resharpened to near-new performance repeatedly, making it a cost-effective long-term investment compared to disposable or coated steel alternatives.
• Right-Hand (RH) Rotation - compatible with the vast majority of multi-spindle CNC boring machines, boring centers, and panel processing equipment running standard RH spindle configurations.

Why This Product

• Built for Through-Hole Dowel Applications up to 30mm Panel Thickness - with a 35mm cutting height and 70mm total length, this bit is specifically sized to drill clean through-holes in panels commonly used in flatpack and cabinet furniture manufacturing without requiring extended-reach tooling.
• Engineered for Difficult Composites and Hardwoods - the super-micrograin carbide body and negatively ground spur geometry handle abrasive materials like particle board, MDF, HDF, and veneered wood that rapidly dull conventional steel boring bits, giving you longer intervals between tool changes.
• Resharpenable Solid Carbide for Lower Cost Per Hole - because the entire bit is one solid carbide unit, it can be resharpened an almost infinite number of times, unlike tipped or coated drills that lose their geometry after a fixed number of resharpenings, making it a practical choice for high-volume production shops.
• Optimized for CNC Routers and High-Speed Boring Units - the balanced centre point, reduced-resistance plunge edge, and rigid oversized cylindrical head combine to deliver reliable, repeatable results on automated equipment where consistent hole quality directly impacts assembly efficiency.
