CMT XTreme Solid Carbide Twist Drill - 5mm Left-Hand Rotation by CMT is a precision-engineered solid carbide twist drill designed for through-hole drilling on CNC boring machines and multi-spindle boring centers. Built from premium HWM solid carbide, this 5mm left-hand spiral drill delivers consistent, clean results in panel processing, furniture manufacturing, and dowel connection applications. The left-hand (LH) rotation and negatively ground spur sharpening make it an ideal choice for use with CMT 364 and 365 adapter systems, giving production shops a reliable solution for high-volume boring operations.

Key Features

• Premium HWM Solid Carbide Construction - the full solid carbide body delivers exceptional wear resistance and edge retention, extending tool life during demanding production runs in hardwood, softwood, and engineered sheet goods.
• XTreme Negatively Ground Spur Sharpening - the extreme precision sharpening on the cutting spurs produces clean entry and exit holes, reducing tearout and improving hole quality in laminates, MDF, chipboard, and plywood.
• 2 Precision Ground Cutting Edges (Z2) - dual precision-ground cutting edges ensure balanced cutting forces and smooth chip evacuation, contributing to accurate, repeatable hole sizing across large production runs.
• 2 Spiral Flutes - twin spiral flutes efficiently clear chips from the cutting zone during through-hole drilling, reducing heat buildup and maintaining consistent drilling performance.
• 120 deg. V-Point Tip Geometry - the 120 deg. point angle provides precise hole positioning and a controlled entry cut, minimizing wandering and supporting accurate dowel-hole alignment.
• Common Shank Design (S=D) - the shank diameter matches the drill diameter at 5mm, allowing direct compatibility with CMT 364 and 365 adapters and bushings without the need for reduction sleeves.
• Left-Hand (LH) Rotation - designed specifically for left-hand spindle positions on multi-spindle CNC boring machines, enabling balanced paired drilling operations alongside right-hand drill sets.
• 5mm Drilling Diameter with 28mm Cutting Length - the 28mm usable cutting depth and 60mm total length suit standard through-hole panel thicknesses common in cabinet and furniture production.

Why This Product

• Purpose-Built for CNC Multi-Spindle Boring - the common shank-to-diameter ratio and compatibility with CMT 364 and 365 adapter systems make this drill a direct-fit solution for multi-spindle boring centers, eliminating adaptation complexity on the production floor.
• Left-Hand Rotation Fills a Critical Need - left-hand spiral drills are required for specific spindle positions on CNC boring machines; this 5mm LH model pairs with right-hand drills to complete symmetric hole patterns for dowel connections and panel joinery.
• HWM Solid Carbide Supports High-Speed Production - solid carbide construction handles the continuous, high-cycle demands of furniture and panel manufacturing without the rapid edge degradation common in lower-grade tooling, reducing downtime for tool changes.
• Precision Sharpening Protects Finished Surfaces - the XTreme negatively ground spurs are engineered to produce chip-free edges in sensitive materials like laminates and MDF, protecting finished surfaces where surface quality directly affects product value.
