CMT 363.040.42 V-Point Solid Carbide Twist Drill by CMT is engineered for precise through-hole drilling on CNC boring machines, delivering clean, accurate bores in a wide range of wood-based materials. With a 5/32 in. (4mm) diameter, left-hand rotation, and a 60 deg. V-point sharpening geometry, this twist drill is built from solid carbide (HWM grade) for exceptional durability and consistent performance in high-volume production environments. Whether you are running softwoods, hardwoods, MDF, or laminates on a multi-spindle boring center, this left-hand carbide drill provides the cutting precision and wear resistance that production woodworking demands.

Key Features

• Solid Carbide (HWM) Construction - the premium carbide material resists wear at high spindle speeds, extending tool life and reducing replacement frequency in continuous production drilling cycles.
• V-Point 60 deg. Sharpening Geometry - the shallow V-point angle centers accurately on the workpiece surface, reducing tear-out and producing cleaner entry holes in chipboard, MDF, plywood, and solid wood.
• Left-Hand (LH) Rotation - designed specifically for left-hand spindle positions on CNC boring machines, ensuring the cutting edges engage the material correctly and chips evacuate efficiently without recutting.
• Common Shank Design (Shank Diameter Equals Drill Diameter, 4mm) - the shank matches the cutting diameter exactly, allowing direct, secure mounting into CMT 364 adapters and 365 bushings without requiring an oversized collet or special chuck.
• 2-Flute, 2-Edge Configuration - dual cutting edges balance cutting forces and promote smooth chip evacuation, reducing heat buildup and helping maintain dimensional accuracy across long production runs.
• 27mm Cutting Height with 55mm Total Length - the cutting height provides adequate depth for standard cabinet-making and furniture through-hole applications, while the compact overall length suits confined multi-spindle head configurations.

Why This Product

• Left-hand spindle positions on CNC boring machines require a purpose-built LH twist drill - this drill is specifically ground for left-hand rotation so cutting forces and chip flow work with the spindle direction rather than against it, protecting bore quality and tool life.
• The solid carbide construction handles the abrasive nature of MDF, HDF, chipboard, and laminates far better than high-speed steel alternatives, meaning fewer tool changes and more consistent hole quality across a production shift.
• At 4mm diameter with a matching 4mm shank, this drill fits directly into CMT 364 series adapters and 365 bushings, making it a straightforward drop-in replacement or addition to an existing CMT boring machine tooling setup.
• The 60 deg. V-point geometry is optimized for through-hole work in panel materials and solid wood, providing accurate self-centering entry that reduces the need for pre-drilling or secondary finishing of hole openings.
