CMT 314.050.11 Dowel Drill for Through Holes - 5 x 35 x 70mm RH is a precision-engineered, carbide-tipped boring tool designed for drilling clean through holes in panel materials used in furniture manufacturing and cabinetry. Built on a super-strength steel body with a tungsten carbide (HW) cutting head, this right-hand rotation drill delivers consistent, accurate dowel bores in chipboard, MDF, hardwood, softwood, plywood, laminates, and coated panels. The 5mm cutting diameter and 35mm cutting height make it well-suited for through-hole dowel joinery in panels up to that depth, while the total length of 70mm provides the reach needed for multi-spindle and CNC boring machine applications.

Key Features

• Tungsten Carbide (HW) Cutting Head - hard-wearing carbide material maintains a sharp cutting edge longer than high-speed steel, reducing tool replacement frequency in high-volume panel drilling operations.
• 2 Precision-Ground Cutting Edges (Z2) - dual cutting edges work together to produce smooth, accurate bore walls on every pass, minimizing tearout in chipboard, MDF, and laminated panels.
• Precision Balanced Centre Point - centers the drill on target with accuracy, preventing wandering at the start of the cut and ensuring hole placement consistency across repeated drilling cycles.
• 2 Spiral Flutes - efficiently evacuate chips and sawdust from the bore during drilling, reducing heat buildup and preventing clogging that could damage the workpiece or slow production.
• PTFE-Coated Spiral Portion - the orange or black PTFE coating on the spiral prevents pitch and adhesive buildup, keeping the flutes clear and extending the working life of the drill in glue-prone or resinous materials.
• Super-Strength Steel Body - provides a rigid, durable backbone for the carbide head, resisting flex and vibration during high-speed boring for reliable, repeatable hole quality.
• Parallel Shank with Driving Flat and Length Adjusting Screw - the 10 x 26mm shank locks securely into multi-spindle boring machine chucks, with a driving flat that prevents rotation slippage and an adjusting screw for precise depth setting.
• Right-Hand (RH) Rotation - compatible with standard right-hand boring machine spindles used in the vast majority of CNC boring centers and multi-spindle panel processing equipment.

Why This Product

• The 5mm cutting diameter and 35mm cutting height directly match the requirements of standard dowel through-hole joinery, making this drill a purpose-built solution rather than a general-purpose bit adapted to the task.
• The PTFE-coated flutes combined with the HW carbide head address two of the most common causes of early tool wear - pitch buildup and edge dulling - resulting in longer intervals between tool changes on busy production lines.
• The precision balanced centre point and dual precision-ground cutting edges work together to produce clean entry and exit holes without blowout, which is critical when drilling through decorative laminates and coated panels where surface quality cannot be compromised.
• The 10 x 26mm parallel shank with driving flat and length adjusting screw is engineered for direct, secure mounting in multi-spindle CNC boring machines and boring centers - no adapters required for compatible machines, simplifying setup and reducing runout.
