CMT 311.070.41 Dowel Drill - 7 x 35 x 70mm Right-Hand is a solid carbide boring bit engineered for precision dowel hole boring in furniture manufacturing, cabinet making, and panel processing applications. Built from premium super micrograin carbide, this 7mm diameter dowel drill delivers exceptionally clean, flat-bottom bores in hardwood, MDF, particle board, and veneered wood - making it a reliable choice for both high-speed boring units and CNC routers.

Key Features

• Solid carbide (HW) construction - the entire bit is formed from premium super micrograin carbide sourced from Luxembourg, providing greater structural integrity than carbide-tipped alternatives and supporting an almost infinite number of resharpenings, reducing long-term tooling costs.
• Curved, negatively ground spurs (2 spurs) - the unique tip geometry produces exceptionally clean bore walls and flat-bottom holes with no rough edges or tearout, which is critical for tight-tolerance dowel joinery and furniture assembly quality.
• Centre-point balanced tip design - promotes accurate, self-centering entry into the workpiece, reducing the risk of drift or misaligned holes during production runs.
• Plunge edge extends to the centre of the bit - reduces drilling resistance and increases production speed, allowing the bit to clear material more efficiently at high cycle rates.
• Cylindrical head larger than traditional tips - provides exceptional resistance to prolonged use, maintaining cutting performance even under demanding, continuous-duty boring conditions.
• Extreme sharpening rating - the solid carbide body withstands repeated resharpening cycles, maximizing the usable life of the bit and lowering cost-per-hole over time.
• 2-flute, right-hand (RH) rotation - optimized chip evacuation and cutting balance for right-hand spindle configurations on CNC boring centers and multi-spindle machines.
• 10 x 30mm shank - compatible with standard boring machine chucks and adapter systems used in panel processing centers and CNC boring equipment.
• 35mm cutting height with 70mm total length (long series) - provides the reach needed for deeper blind holes in thick panels without compromising rigidity or accuracy.
• Ideal for hardwood and difficult composites - performs reliably in particle board, MDF, and veneered wood where lesser carbide grades may chip or wear prematurely, delivering consistent bore quality across material types.

Why This Product

• For shops drilling dowel holes in MDF, particle board, or veneered panels at high cycle rates, the solid micrograin carbide body and extended plunge edge actively reduce drilling resistance - translating to faster cycle times and less spindle load.
• The negatively ground curved spurs and centre-balanced tip address one of the most common quality issues in panel boring: rough bore walls and edge tearout that compromise the fit and appearance of dowel joints.
• Unlike carbide-tipped bits that limit resharpening depth to the tip insert, the solid carbide construction of this bit allows repeated resharpening across the full body - a meaningful cost advantage in high-volume production environments.
• With a 10 x 30mm shank and 70mm total length, this bit fits directly into the standard tooling systems of CNC boring centers and multi-spindle boring machines, requiring no special adapters for most panel processing setups.
