High-performance 3-Flute TCT Line Boring Bit designed for woodworking, cabinet production, and CNC drilling systems. Features carbide-tipped cutting edges, fast chip removal, clean entry holes, and long service life. Available in 2.5–10 mm sizes for multi-spindle and line boring applications.
The 3-Flute TCT Line Boring Bit is a high-performance woodworking drill bit engineered for cabinet manufacturing, panel furniture production, and CNC drilling systems. Featuring industrial-grade TCT (Tungsten Carbide Tipped) edges and a three-flute cutting geometry, this bit delivers cleaner holes, faster chip evacuation, and superior durability compared to standard boring bits.
Optimized for multi-spindle boring machines, line boring systems, and automated CNC drilling equipment, it provides stable cutting performance on MDF, particle board, plywood, laminated panels, and solid wood.
The 3-flute design ensures smooth cutting, cleaner hole walls, and enhanced chip removal for high-speed drilling.
Industrial carbide-tipped edges maintain long-lasting sharpness and deliver extended tool life in heavy-duty production.
Compatible with line boring machines, CNC drilling centers, and multi-row drilling units.
Reduces vibration, heat buildup, and maintains tight diameter tolerance for consistent quality.
Perfect for MDF, particle board, plywood, solid wood, and laminated boards.
