CMT 375.060.12 4 Flute Dowel Drill for Through Holes - 15/64" x 2-3/4" LH is a precision-engineered left-hand rotation through-hole dowel drill designed for CNC boring machines and multi-spindle panel processing centers. With a 6mm cutting diameter, 40mm cutting height, and 70mm total length, this long-series drill delivers clean, consistent through-holes in chipboard, MDF, hardwood, softwood, plywood, and coated laminates - giving woodworking professionals and panel fabricators a reliable tool for high-volume boring operations.

Key Features

• Tungsten Carbide (HW) Construction - carbide-grade material maintains a sharp cutting edge through repeated use in abrasive materials like MDF, chipboard, and laminates, reducing downtime from frequent tool changes.
• Left-Hand (LH) Rotation - designed specifically for left-hand spindle positions on multi-spindle CNC boring machines and boring centers, ensuring the tool seats and cuts correctly without vibration or pullout.
• Through-Hole Geometry with 60 deg. Sharpening Angle - the through-hole point configuration and 60 deg. tip angle produce clean entry and exit on both faces of a panel, reducing tearout and eliminating the need for secondary finishing.
• 2-Flute Cutting Head - efficient chip evacuation through the flute geometry prevents material buildup inside the bore, resulting in smooth, accurate hole walls even at production speeds.
• 10x20mm Shank - the fixed shank dimensions ensure a secure, repeatable fit in compatible boring machine spindles, maintaining drilling accuracy across long production runs.
• 40mm Cutting Height - the extended cutting length accommodates panels across a range of thicknesses, making this drill a versatile option for through-hole applications in panel processing.
• 70mm Total Length (Long Series) - the long-series body provides the reach needed for deep spindle housings on CNC boring centers, allowing the drill to be used without adapters in most standard configurations.

Why This Product

• The left-hand rotation configuration makes this drill a direct fit for LH spindle positions on multi-spindle CNC boring machines and panel processing centers - no modification or adapter required.
• The through-hole point geometry at a 60 deg. sharpening angle is specifically engineered to cut cleanly through the full panel thickness, producing flat, burr-free exit holes - critical for furniture panels and coated boards where appearance matters.
• Carbide (HW) construction stands up to the abrasive nature of chipboard, MDF, HDF, and laminated panels, delivering longer service life than high-speed steel alternatives in production environments.
• The 10x20mm shank and 70mm long-series length match the spindle requirements of industry-standard CNC boring centers and multi-spindle machines, providing a drop-in solution for through-hole dowel drilling operations.
