CMT XTreme Solid Carbide Twist Drill - 3x27x55mm Left-Hand Rotation is a precision-engineered, solid carbide boring tool built for CNC boring machines and multi-spindle boring centers. Manufactured from premium HWM solid carbide, this left-hand twist drill delivers reliable through-hole drilling performance in panel processing, furniture manufacturing, and dowel connection applications. With an extreme sharpening profile and negatively ground spurs, it produces clean entry and exit cuts in a wide range of wood-based materials - making it a go-to choice for production shops that demand consistent, repeatable bore quality.

Key Features

• Premium HWM Solid Carbide Construction - the full-carbide body provides exceptional wear resistance and edge retention, extending tool life in high-cycle CNC boring production environments.
• XTreme Sharpening with Negatively Ground Spurs - the extreme sharpening geometry and negative spur grind work together to minimize tear-out and produce clean, accurate bore walls in hardwood, softwood, and engineered panel materials.
• 2 Precision Ground Cutting Edges (Z2) - dual precision-ground cutting edges deliver balanced cutting forces and consistent hole geometry, reducing vibration and improving bore quality on every pass.
• 2 Spiral Flutes - twin spiral flutes efficiently evacuate chips from the bore, preventing clogging and heat buildup during through-hole drilling at production speeds.
• Left-Hand (LH) Rotation - engineered specifically for left-hand spindle positions on CNC boring machines and multi-spindle boring centers, ensuring correct cutting action and clean hole entry on the appropriate spindle side.
• Common Shank Design (S=D, 3mm Shank) - the shank diameter matches the drill diameter at 3mm, allowing direct compatibility with CMT 364 and 365 adapters and bushings without intermediate tooling.
• Compact 55mm Total Length with 27mm Cutting Depth - the optimized overall length and cutting height suit standard CNC boring machine spindle configurations, keeping the tool stable and reducing deflection during operation.

Why This Product

• The solid carbide HWM construction paired with extreme sharpening makes this drill well-suited for demanding production drilling in furniture panels, chipboard, MDF, and hardwood - where edge life and clean bore quality are critical to throughput.
• The left-hand rotation designation addresses a specific and essential need on CNC boring machines and multi-spindle boring centers that have dedicated LH spindle positions - using a right-hand drill in an LH spindle position produces incorrect cutting action and poor hole quality.
• The common shank design (shank diameter equals drill diameter at 3mm) simplifies tooling setup by fitting directly into CMT 364 and 365 series adapters, reducing changeover time and adapter inventory requirements.
• With negatively ground spurs and dual precision cutting edges, this drill is designed to produce dowel connection holes with tight tolerances and smooth walls - directly supporting the structural requirements of cabinet and furniture assembly.
