3-Flute TCT Euro Hinge Boring Bit — Industrial CNC Hinge Cup Drilling Tool

The 3-Flute TCT Euro Hinge Boring Bit is a high-performance industrial woodworking drilling tool designed for European concealed hinge cup hole drilling in cabinet doors and panel furniture. Engineered with three precision-ground cutting wings, a high-density carbide-tipped (TCT) structure, and optimized flat-bottom boring geometry, it delivers exceptionally clean hinge cup holes, minimal tear-out, and long-lasting performance across MDF, particle board, plywood, melamine panels, and solid wood.

The center-point design ensures accurate drilling alignment, making it ideal for CNC hinge boring machines, automatic drilling centers, and multi-spindle line boring systems used in large-scale cabinet production.

This bit is built specifically for 35mm Euro hinge drilling, 40mm hinge cup drilling, and professional cabinet door hinge installation workflow, providing unmatched consistency for high-volume manufacturing lines.
