CMT XTreme Solid Carbide Twist Drill - 2.5mm (7/64 in.) Left-Hand Rotation by CMT is a precision-engineered, solid carbide boring tool built for through-hole drilling on CNC boring machines and multi-spindle boring centers. Designed with a 120 deg. V-point and extreme negative-sharpening ground spurs, this left-hand twist drill delivers clean, accurate holes in a wide range of wood-based materials - making it a go-to choice for furniture manufacturing, panel processing, and dowel-joinery production work.

Key Features

• Solid carbide (HWM) construction - premium super-strength carbide provides exceptional wear resistance and long service life in high-speed production drilling applications.
• Extreme negative-sharpening ground spurs - the XTreme sharpening geometry produces clean entry and exit holes, reducing tearout and improving finish quality on laminates, MDF, and hardwood panels.
• 120 deg. V-point geometry - optimized point angle centers the drill accurately and promotes consistent hole placement, critical for precise dowel alignment and panel-to-panel joinery.
• 2 precision-ground cutting edges (Z2) with 2 spiral flutes - dual cutting edges deliver balanced cutting action while the spiral flutes evacuate chips efficiently, reducing heat buildup and extending tool life.
• Left-hand (LH) rotation - engineered specifically for left-hand spindles on CNC boring machines and multi-spindle boring centers, ensuring correct cutting direction and optimal chip clearance.
• Common shank design (S=D, 2.5mm shank equals 2.5mm drill diameter) - fits directly into CMT 364 and 365 adapters and bushings without adapting hardware, simplifying setup on boring machine spindles.
• 27mm cutting height with 55mm total length - compact overall length suits standard boring machine spindle configurations while providing sufficient flute length for through-hole drilling in typical panel thicknesses.

Why This Product

• Engineered for CNC boring machine compatibility - the common shank (S=D) and left-hand rotation make this drill a direct-fit solution for left-hand spindles on CNC boring machines and multi-spindle boring centers using CMT 364/365 adapters, eliminating guesswork in tooling selection.
• XTreme sharpening for demanding production environments - the extreme negative-ground spur geometry is specifically designed to handle the abrasive cutting demands of chipboard, MDF, HDF, laminates, and hardwood at production speeds, where edge retention is critical.
• Precision dowel and hardware hole drilling - the 120 deg. V-point and dual precision-ground edges work together to deliver consistently accurate hole placement for dowel connections, a cornerstone requirement in furniture and cabinet manufacturing.
• 2.5mm diameter suits fine-pitch boring layouts - the 2.5mm (7/64 in.) diameter addresses close-tolerance hole patterns common in panel processing, giving production operators a reliable small-diameter carbide drill without sacrificing rigidity or accuracy.
