CMT 4 Flute Dowel Drill for Through Holes - 13/64" x 2-3/4" RH is a precision-engineered tungsten carbide (HW) boring tool designed for clean, accurate through-hole drilling in panel processing applications. Built on a long-series 70mm platform with a 10x20mm shank, this right-hand rotation drill delivers consistent results in solid wood, chipboard, MDF, HDF, plywood, laminates, and coated panels. Whether you are running a multi-spindle CNC boring machine, a CNC boring center, or a standard boring machine with an adapter or chuck, this 5mm diameter dowel drill is engineered to produce precise through-holes with minimal tearout and tight tolerances on every pass.

Key Features

• Tungsten Carbide (HW) Construction - hard-wearing carbide material maintains a sharp cutting edge far longer than standard high-speed steel, reducing tool change frequency during production runs on panel processing equipment.
• 5mm Diameter with 40mm Cutting Height - optimized proportions allow the drill to bore clean through-holes in panels across a meaningful range of material thicknesses, making it versatile for common cabinet and furniture panel dimensions.
• 70mm Total Length Long-Series Design - the extended overall length provides clearance and reach needed for through-hole applications on CNC boring centers and multi-spindle machines without risking chuck interference.
• 10x20mm Shank - a robust, precisely dimensioned shank ensures secure, vibration-resistant seating in compatible boring machine spindles, promoting consistent hole location and finish quality.
• Right-Hand (RH) Rotation - matches the standard spindle direction of the majority of CNC boring centers and panel processing equipment, enabling straightforward, direct installation without adapter modification.
• Through Holes 60 deg. Geometry - the 60 deg. point geometry is specifically configured for through-hole boring, producing clean entry and exit cuts that reduce the need for secondary deburring or sanding operations.
• 2-Tooth Cutting Configuration - balanced two-flute geometry supports efficient chip evacuation during through-hole drilling, helping to maintain cut quality and reduce heat buildup in the material.

Why This Product

• Purpose-Built for Through-Hole Boring - unlike general-purpose twist drills, this bit is configured specifically for through-hole applications with a 60 deg. point geometry and a 40mm cutting height that clears typical panel thicknesses cleanly from entry to exit.
• Long-Series Platform Adds Versatility - the 70mm overall length gives this drill reach that shorter-series bits cannot provide, making it suitable for thicker panels and machines where spindle-to-table clearance demands additional tool length.
• Carbide (HW) Durability Reduces Downtime - tungsten carbide construction holds cutting geometry longer than softer tool materials, meaning fewer interruptions for tool changes during high-volume cabinet, furniture, or panel processing production.
• Compatible with Standard CNC and Manual Boring Equipment - the 10x20mm shank and right-hand rotation make this drill a direct fit for multi-spindle CNC boring machines, boring centers, and boring machines with an adapter or chuck - no special tooling required.
