CMT Dowel Drill 5 x 35 x 70mm Right-Hand by CMT is a solid carbide boring bit engineered for high-precision dowel hole drilling in furniture manufacturing, cabinet making, and panel processing applications. Built from premium quality super micrograin carbide, this right-hand rotation bit delivers exceptionally clean, flat-bottomed bores in hardwood, MDF, particle board, and veneered wood - making it a reliable choice for both high-speed multi-spindle boring units and CNC routers.

Key Features

• Solid Super Micrograin Carbide Construction (HW) - the entire bit is manufactured from a single piece of premium carbide, meaning it can be resharpened an almost infinite number of times without degrading structural integrity, extending the usable life of the tool significantly compared to carbide-tipped alternatives.
• Curved, Negatively Ground Spurs (2 spurs) - the unique tip geometry produces exceptionally clear bores with no rough edges or tearout, resulting in cleaner dowel joints and reducing the need for secondary finishing or fitting.
• Centre-Balanced Point - the balanced centre point reduces lateral drift at entry, keeping bore placement accurate and consistent across repeated operations on CNC boring centers and multi-spindle machines.
• Plunge Edge Running to Centre - reduces drilling resistance and increases production speed, so the bit cuts faster with less effort while maintaining clean bore walls throughout the full 35mm cutting height.
• Extreme Sharpening Rating - the bit holds its edge through demanding production runs and can be resharpened to exacting tolerances, lowering the cost per hole over the tool's lifetime.
• 10 x 30mm Parallel Shank - sized for compatibility with standard multi-spindle boring heads, CNC boring centers, and panel processing machines that accept this shank format.
• Right-Hand (RH) Rotation - matches the standard spindle direction of the majority of industrial boring machines and CNC routers, allowing direct drop-in installation without adapter changes.
• 2-Flute, 2-Spur Design - the twin cutting edges and twin spurs work together to score and clear material efficiently, producing smooth bore walls in difficult composites such as particle board, MDF, and veneered panels.

Why This Product

• Designed specifically for dowel connection boring, this bit produces the flat-bottomed, smooth-walled holes that dowel joints require - reducing assembly rejects and improving joint consistency in furniture and cabinet production.
• The solid carbide body offers a significant safety advantage over carbide-tipped bits: because there is no brazed joint that can fail under heat or impact, the bit maintains structural integrity even during high-speed CNC operations.
• Its extreme sharpening rating and solid one-piece carbide construction make this bit well suited for high-volume panel processing environments where tool changes are costly and consistent bore quality is non-negotiable.
• Optimized for difficult materials including MDF, particle board, and veneered wood - materials that quickly dull lesser bits - this dowel drill maintains cutting performance across demanding production runs.
