CMT 374.050.11 4 Flute Dowel Drill for Through Holes - 13/64" x 2-17/64" RH is a precision carbide-tipped boring tool engineered by CMT for clean, accurate through-hole drilling in solid wood, chipboard, MDF, laminates, and coated panels. With a 5mm cutting diameter, right-hand rotation, and a through-hole geometry ground at 60 deg., this dowel drill is purpose-built for use in multi-spindle CNC boring machines, boring centers, and panel processing equipment where repeatable hole quality and exit-side cleanliness are essential.

Key Features

• Tungsten Carbide (HW) Cutting Material - hard-metal carbide construction delivers extended edge life and consistent cutting performance across solid wood, MDF, chipboard, and laminated panels, reducing tool change frequency on high-production boring lines.
• Through-Hole Geometry Ground at 60 deg. - the through-hole sharpening angle is optimized to produce clean entry and exit on both faces of the workpiece, preventing blowout and eliminating the need for secondary cleanup on finished panels.
• Right-Hand (RH) Rotation - matches the standard spindle direction of CNC boring centers and multi-spindle machines, ensuring direct compatibility without adapters or special toolholders.
• 5mm Cutting Diameter x 30mm Cutting Height - the generous cutting height accommodates a range of panel thicknesses in a single pass, making this bit versatile for cabinet assembly, furniture manufacturing, and case goods production.
• 10x20mm Shank - the robust shank dimensions provide a secure, stable seat in standard boring machine chucks, reducing runout and contributing to straight, precisely located holes.
• 2-Tooth Flute Design - the dual-tooth geometry efficiently evacuates chips from the bore during the cut, preventing chip packing that can cause heat buildup and surface damage inside the hole.
• 57.5mm Total Length - the overall length is sized to reach through standard panel thicknesses while remaining stiff enough to resist deflection, keeping hole position accurate even at production feed rates.

Why This Product

• Clean through-holes without blowout - the 60 deg. through-hole sharpening geometry is specifically designed to exit the workpiece cleanly, which is critical when both faces of a panel are visible in a finished furniture or cabinet assembly.
• Built for CNC and multi-spindle production environments - the 10x20mm shank and right-hand rotation make this bit a direct fit for CNC boring centers and panel processing lines, minimizing setup time and tooling compatibility issues.
• Carbide durability for demanding materials - the HW (tungsten carbide) cutting material handles abrasive engineered wood products like chipboard, MDF, and laminates where high-speed steel bits wear rapidly, keeping production running longer between tool changes.
• Precise 5mm dowel diameter - the 5mm cutting diameter is a standard dowel pin size used widely in furniture joinery and case goods construction, making this bit a practical choice for high-volume doweling operations.
