CMT 310.070.41 Dowel Drill 7 x 27 x 57.5mm RH is a solid carbide boring bit engineered by CMT for precise, high-speed dowel hole drilling in furniture manufacturing, cabinet making, and panel processing. Built entirely from premium quality super micrograin carbide, this 7mm diameter drill delivers exceptionally clean bores in hardwood, MDF, particle board, veneered wood, and difficult composite panels - making it a reliable choice for both CNC router applications and multi-spindle boring machines. The right-hand rotation design and two-flute configuration reduce drilling resistance and increase production throughput on demanding industrial boring operations.

Key Features

• Solid super micrograin carbide construction (HW) - the entire bit is formed from one solid unit of premium carbide, delivering exceptional structural integrity, extra safety during high-speed operation, and an almost infinite number of resharpenings that extend the useful life of the tool well beyond conventional carbide-tipped alternatives.
• Curved, negatively ground spurs (2 spurs / V2) - the unique tip geometry produces exceptionally clear bore walls and flat-bottom holes with no rough edges or tearout, ensuring clean, furniture-quality results even in veneered and coated panels.
• Centre-point balanced tip design - keeps the drill perfectly centered on entry, reducing wander and improving hole-position accuracy in high-speed multi-spindle and CNC boring applications.
• Plunge edge extending to the centre of the bit - reduces cutting resistance during plunge entry, increasing production speed and lowering load on spindle motors during continuous panel drilling cycles.
• Cylindrical head larger than traditional tip designs - provides greater resistance to the mechanical stresses of prolonged use, maintaining dimensional accuracy and bore quality through extended production runs.
• Extreme sharpening classification - the solid carbide body accepts repeated precision resharpening, making this drill a long-term investment that maintains cutting performance and bore quality across its entire service life.
• 10 x 27mm parallel shank with driving flat and adjustable screw length - ensures secure, repeatable seating in standard boring machine chucks and CNC toolholders, preventing slippage during high-cycle production use.
• 2 cutting edges (Z2) with 2 spiral flutes - balances chip evacuation with cutting efficiency, reducing heat buildup and keeping bores clean in dense materials such as MDF and particle board.
• Ideal for hardwood and difficult composites including MDF, particle board, and veneered wood - the solid carbide formulation resists the abrasive qualities of engineered panels that quickly degrade conventional high-speed steel or carbide-tipped bits.

Why This Product

• Built for high-speed CNC and multi-spindle boring machines - the solid carbide body, balanced centre point, and precision-ground geometry are specifically designed for the demanding feed rates and spindle speeds of CNC routers and automated panel boring centres, where accuracy and repeatability matter most.
• Clean bores in difficult composite materials without tearout - the curved, negatively ground spurs and extended plunge edge address the most common problem in panel drilling: fraying, chipping, and rough bore walls in MDF, particle board, and veneered surfaces.
• Resharpening extends total cost of ownership - because the drill is a solid unit of super micrograin carbide rather than a tipped design, it can be resharpened many times over its life rather than discarded when the tip wears, reducing per-hole tooling cost in high-volume production environments.
• Compact 57.5mm overall length for tight spindle spacing - the short-series 57.5mm total length is suited to multi-spindle boring heads where adjacent spindle clearance is limited, allowing this drill to be used in dense tooling configurations without interference.
