CMT 314.055.11 Dowel Drill for Through Holes - 7/32" x 35 x 70mm, Right-Hand Rotation is a precision 2-flute carbide-tipped boring tool engineered for clean through-hole drilling in panel processing and furniture manufacturing. Built on a super-strength steel body with a tungsten carbide (HW) cutting head, this dowel drill is designed for high-volume production use in multi-spindle boring machines and CNC boring centers. The spiral portion carries a P.T.F.E. coating that reduces friction and prevents pitch and resin buildup during repeated drilling cycles, keeping the tool cutting cleanly through chipboard, MDF, hardwood, softwood, plywood, laminates, and coated panels.

Key Features

• HW (Tungsten Carbide) Cutting Head - delivers long-lasting edge retention through dense or abrasive panel materials such as MDF, chipboard, and laminates, reducing the frequency of tool changes in production environments.
• P.T.F.E.-Coated Spiral Flutes - the orange or black polytetrafluoroethylene coating on the spiral portion prevents pitch and glue buildup, so the drill evacuates chips cleanly and maintains consistent bore quality over extended runs.
• Precision-Balanced Centre Point - the HW head features a precision-balanced centre point that locates accurately at the bore entry, eliminating wander and producing repeatable hole positioning critical for dowel joint alignment.
• 2 Precision-Ground Cutting Edges (Z2) - dual precision-ground flutes produce clean, smooth bore walls on both entry and exit, minimizing blowout on through-hole applications and reducing secondary finishing work.
• 2 Spiral Flutes for Active Chip Evacuation - the twin-flute spiral geometry pulls chips up and out of the bore during drilling, preventing clogging and heat buildup that can damage panel surfaces or shorten tool life.
• Parallel Shank with Driving Flat and Length-Adjusting Screw - the 10 x 26mm parallel shank includes a driving flat to prevent slipping under torque and a length-adjusting screw for precise depth setting in multi-spindle heads and boring machine chucks.
• Right-Hand (RH) Rotation - matches the standard spindle rotation of the vast majority of CNC boring centers and multi-spindle panel processing machines, ensuring direct compatibility without adapters.
• 70mm Total Length with 35mm Cutting Height - the long-series geometry accommodates panels requiring a full through-hole, with ample cutting depth for typical furniture panel thicknesses.

Why This Product

• The 7/32" diameter with a 35mm cutting height makes this dowel drill well-suited for through-hole boring in furniture panels where a consistent, clean bore is required on both the entry and exit face - eliminating blowout that would otherwise require rework or scrap the panel.
• The combination of an HW (tungsten carbide) head and P.T.F.E.-coated spiral addresses two of the most common failure modes in high-cycle panel drilling: edge wear from abrasive materials and chip packing from glue or resin residue - both of which reduce hole quality and shorten tool intervals.
• The parallel shank with driving flat and length-adjusting screw allows precise positioning in multi-spindle boring heads, so operators can set consistent boring depth across an entire spindle bank without individual re-measurement - critical for furniture production line efficiency.
• With right-hand rotation and a standard 10 x 26mm parallel shank, this drill installs directly into compatible CNC boring centers and panel processing machines without the need for special adapters, making it a practical drop-in tooling choice for dowel joint production.
