CMT 4 Flute Dowel Drill for Through Holes - 25/64" x 2-3/4" RH is a precision-ground, carbide-tipped boring tool engineered for clean, accurate through-holes in panel processing applications. Built on a long-series 70mm platform, this right-hand rotation drill handles solid wood, chipboard, MDF, HDF, hardwood, softwood, plywood, laminates, and coated panels with consistent results. Whether you are running a multi-spindle CNC boring machine, a CNC boring center, or a standard boring machine fitted with an adapter or chuck, this dowel drill delivers flat-bottomed, splinter-free bores that meet the tight tolerances demanded by cabinet and furniture production workflows.

Key Features

• Tungsten Carbide (HW) Cutting Material - harder and more wear-resistant than high-speed steel, carbide maintains a sharp edge longer through high-cycle panel boring, reducing downtime for tool changes and sharpening intervals.
• Through-Hole Geometry with 60 deg. Point Angle - optimized for boring completely through panels, this geometry evacuates chips efficiently and prevents heat buildup, producing clean entry and exit holes on both faces of the workpiece.
• 2-Flute Design - balanced flute configuration promotes smooth chip ejection during through-boring passes, reducing the risk of clogging or burning in dense sheet materials such as MDF and coated panels.
• 10mm x 20mm Shank - standard sizing for direct compatibility with multi-spindle CNC boring heads and panel processing centers, ensuring secure clamping and minimal runout at high spindle speeds.
• 40mm Cutting Height - substantial cutting length accommodates panels across a practical range of thicknesses, making this drill versatile across different panel processing tasks without tool changes.
• 70mm Total Length (Long Series) - the extended overall length provides clearance in deep spindle housings and allows through-boring of thicker panel assemblies that shorter series drills cannot reach.
• Right-Hand (RH) Rotation - correct rotation direction for standard CNC boring spindles and conventional boring machines, ensuring compatibility with the majority of panel processing equipment setups.
• PTFE Non-Stick Coating - the CMT orange and black PTFE coating prevents resin, glue, and pitch from accumulating on the spiral, extending tool life and maintaining consistent bore quality over time.

Why This Product

• The long-series 70mm body allows this through-hole dowel drill to bore completely through panel thicknesses that standard-length drills cannot accommodate, making it the right choice for production environments processing thicker substrates such as doubled-up chipboard or hardwood panels.
• The tungsten carbide (HW) cutting material and PTFE coating work together to extend sharpening intervals and reduce pitch buildup, lowering the cost-per-hole over long production runs in demanding materials like MDF and laminates.
• The 10mm x 20mm shank is designed for direct drop-in use on multi-spindle CNC boring machines and panel processing centers - no special adapters required in most standard boring head configurations, saving setup time.
• With a 60 deg. through-hole point geometry and a 40mm cutting height, this drill produces clean, consistent through-bores in chipboard, MDF, hardwood, softwood, plywood, and coated panels, making it a single solution across the full range of common cabinetry and furniture sheet goods.
