CMT Solid Carbide Dowel Drill for Through Holes - 5 x 40 x 70mm Right-Hand is a premium-grade boring bit engineered for clean, precise through-hole drilling in furniture panel processing, cabinetry, and dowel joinery applications. Built entirely from super-micrograin carbide (HWM), this 5mm diameter drill delivers exceptional cutting performance on hardwood, particle board, MDF, veneered panels, and coated composites. With 2 precision-ground cutting edges and a balanced center point, it is purpose-built for high-speed multi-spindle boring units and CNC machining centers where accuracy and throughput matter most.

Key Features

• Solid Carbide (HWM) Body - the entire drill is made from premium super-micrograin carbide, providing extreme wear resistance and allowing an almost infinite number of resharpenings, which lowers long-term tooling cost.
• 2 Precision-Ground Cutting Edges (Z2) with Double Angle - dual flutes reduce cutting resistance and increase feed rates, so production speed stays high even on demanding CNC boring runs.
• Curved, Negatively Ground Spurs at the Tip - produces exceptionally clean bore walls and splinter-free exit holes with no rough edges, eliminating the need for secondary cleanup on finished panels.
• Balanced Center Point - ensures accurate hole location on entry without wandering, which is critical when drilling dowel-connection holes to tight positional tolerances.
• Plunge Edge Running to Center - reduces drilling resistance from the start of the cut, allowing faster plunge speeds and reducing load on the spindle motor.
• Parallel Shank with Driving Flat - 10 x 26mm - the driving flat prevents slippage under torque and provides secure clamping in standard boring machine chucks and multi-spindle heads.
• Extreme Sharpening Rating - the carbide grade and geometry are optimized for repeated resharpening cycles, making this drill a long-service investment rather than a disposable tool.
• Right-Hand (RH) Rotation - compatible with standard right-hand spindle configurations on CNC boring centers and multi-spindle panel processing equipment.
• 35mm Cutting Height with 70mm Total Length - the extended cutting zone handles through-hole boring in panels of substantial thickness while keeping overall tool length compact for multi-spindle clearance.

Why This Product

• Furniture and cabinetry manufacturers who need consistently clean through-holes for dowel connections benefit from the negatively ground spur geometry, which virtually eliminates tearout on exit - protecting finished panel faces without adding sanding or trimming steps.
• Shops running high-speed CNC boring centers or multi-spindle machines can take advantage of the reduced drilling resistance from the center-running plunge edge, supporting faster cycle times without sacrificing hole quality.
• The solid carbide (HWM) construction is specifically suited to abrasive sheet materials like particle board, MDF, HDF, and laminates that wear out high-speed steel tooling rapidly - extending intervals between tool changes on production lines.
• Because the drill is a solid carbide unit, it can be resharpened an exceptional number of times rather than discarded, giving high-volume operations a measurable cost-per-hole advantage over disposable tipped alternatives.
