CMT 363.040.12 V-Point Solid Carbide Twist Drill - 120 deg. Sharpening, 4mm, Left-Hand Rotation is a precision-ground, solid carbide boring tool engineered for through-hole drilling on CNC boring machines and multi-spindle boring centers. Built from premium HWM solid carbide, this left-hand (LH) twist drill features a V-point 120 deg. tip geometry with 2 precision-ground cutting edges and 2 spiral flutes, delivering clean, accurate holes in a wide range of panel materials. Designed for use with CMT 364 and 365 adapter systems, it is an essential component for furniture manufacturing, dowel joinery, and high-volume panel processing operations.

Key Features

• Premium HWM Solid Carbide Construction - provides exceptional wear resistance and long service life during high-speed production drilling, reducing downtime and bit replacement frequency.
• V-Point 120 deg. Sharpening - the aggressive V-point geometry centers precisely on entry and shears material cleanly, producing accurate through-holes with minimal tearout in wood-based panel products.
• 2 Precision-Ground Cutting Edges (Z2) - dual cutting edges balanced by precision grinding ensure consistent hole quality, reduced vibration, and smooth chip evacuation during continuous operation.
• 2 Spiral Flutes - twin spiral flutes channel chips up and out of the hole efficiently, preventing clogging and maintaining consistent cut quality in chipboard, MDF, plywood, and similar materials.
• Common Shank Design (S=D, 4mm) - shank diameter equals drill diameter, allowing direct, straightforward fitment into CMT 364 and 365 adapters without the need for reduction bushings or special collets.
• Left-Hand (LH) Rotation - specifically engineered for left-hand spindle positions on CNC boring machines and multi-spindle centers, ensuring proper cutting direction and clean hole formation on LH spindles.
• 4mm Drilling Diameter - a widely used standard diameter for dowel connections and panel joinery, compatible with common 4mm dowel pin systems used across furniture production.

Why This Product

• Designed specifically for use with CMT 364 and 365 adapter systems, this drill integrates directly into existing CMT boring machine setups without requiring additional tooling or adapters beyond those already in the CMT system.
• The V-point 120 deg. tip geometry and dual precision-ground cutting edges produce accurate, repeatable through-holes critical for dowel joinery alignment in furniture and cabinet panel production.
• Solid carbide (HWM) construction handles the abrasive demands of chipboard, MDF, HDF, and laminated panels that quickly wear down lesser tool materials, keeping production lines running longer between tool changes.
• The left-hand rotation specification makes this the correct choice for LH spindle positions on CNC boring centers, eliminating the risk of installing a wrong-rotation bit that would damage workpieces or machine spindles.
