CMT V-Point Solid Carbide Twist Drill - 120 deg. Sharpening, 4mm is a precision-ground, 2-flute carbide boring bit engineered for clean through-hole drilling on CNC boring machines and multi-spindle boring centers. Built from premium HWM solid carbide and featuring a classic V-point 120 deg. tip geometry, this right-hand twist drill delivers consistent, accurate results in panel processing, furniture manufacturing, and dowel connection applications across a wide range of wood-based materials.

Key Features

• Solid HWM carbide construction - premium-grade carbide provides exceptional wear resistance and long tool life in high-speed production boring environments, reducing the need for frequent bit replacement.
• V-point 120 deg. sharpening - this tip geometry centers the bit precisely at entry for accurate, clean through-holes with minimal tear-out, critical in furniture panel and dowel-joint production.
• 2 precision-ground cutting edges (Z2) - dual precision-ground flutes ensure balanced, vibration-free cutting action that protects both the workpiece surface and the spindle of the boring machine.
• 2 spiral flutes - the twin-flute design efficiently evacuates chips during drilling, reducing heat buildup and maintaining cut quality over extended production runs.
• Common shank design (S=D, 4mm shank = 4mm diameter) - the shank and drilling diameter are identical, so the bit fits directly into CMT 364/365 adapters and bushings without the need for a reducer or special toolholder.
• Right-hand (RH) rotation - standard right-hand rotation is compatible with conventional CNC boring machine spindles, making changeover straightforward in production settings.
• Designed for use with CMT 364/365 adapter systems - engineered to work specifically with these adapter series, ensuring a secure, properly aligned fit in multi-spindle boring center configurations.

Why This Product

• For woodworking shops and furniture manufacturers running CNC boring centers, a consistent V-point 120 deg. carbide twist drill like this one reduces scrap from off-center entry holes - the precision-ground tip self-centers on panel surfaces for reliable dowel-hole placement every cycle.
• The HWM solid carbide material handles the abrasive nature of chipboard, MDF, HDF, and laminate panels that would quickly dull lesser tooling - keeping production lines running without constant bit changes.
• With a 4mm diameter and matching 4mm shank, this bit fits directly into CMT 364/365 adapters, so shops already invested in the CMT boring system can expand their drill capacity without sourcing new toolholders or adapters.
• At 55mm total length with 27mm of cutting depth, this drill is sized appropriately for standard panel through-hole and blind-hole boring tasks in cabinet and furniture panel work, giving operators a reliable reach without excess tool deflection.
