TCT Hinge Bit

Achieve flawless hinge pocketing and blind-hole drilling with the SMT Professional TCT Hinge Boring Bit. Specially designed for cabinet makers and joiners, this bit provides fast, smooth, and chip-free boring of cup holes for standard European concealed hinges (such as 35mm cup hinges) and general flat-bottom wood boring.

Constructed with high-density Tungsten Carbide Tipped (TCT) cutting edges, this bit easily slices through dense hardwoods, ply, and highly abrasive engineered boards like MDF and melamine-faced chipboard. The sharp central spur guarantees exact alignment and stability, while outer rim spurs shear through surface fibers before the main cutters engage, ensuring zero breakout or veneer tear-out around the hole perimeter.

Key Features & Benefits

• Superior Carbide Longevity: Micro-grain TCT blades retain their razor edge up to 5x longer than standard HSS bits, making them ideal for high-volume manufacturing.

• Zero-Breakout Clean Edges: Dual outer scribing spurs slice cleanly through top surface laminates, plastic veneers, and wood fibers before the main pocket cut.

• Accurate Center Positioning: Center spur keeps the bit anchored on target, preventing walking or wobbling during handheld drill or drill press operation.

• Heat-Resistant Red Finish: Protective body coating reduces friction, resists resin buildup, and disperses heat rapidly to extend tool service life.

• Universal Tool Fit: Cylindrical steel shank installs securely into standard drill presses, power drills, and CNC boring machinery.
