SMT TCT Hinge Bit

Technical Specifications Overview

Detailed Product Analysis

1. Dual-Material Construction

The tool utilizes a hybrid construction to balance durability and cost-effectiveness.

• High Carbon Steel Body: The main body is forged from high carbon steel, providing the necessary elasticity to absorb vibration and prevent snapping under high torque.

• Tungsten Carbide Teeth: The cutting edges are tipped with industrial-grade Tungsten Carbide. This allows the bit to stay sharp up to 10 times longer than standard steel bits, especially when cutting through abrasive materials like MDF, plywood, and hardwoods.

2. Precision Engineering & Design

With a standard length of 85 mm, this bit is designed for deep-hole boring and through-hole applications.

• The Center Spur: Points the bit exactly where you need it, preventing “walking” or drifting on the workpiece.

• Clean Cutting: The peripheral cutters shear the wood fibers at the edge of the circle, resulting in a flat-bottomed hole that is smooth and splinter-free.

3. Versatile Applications

This bit is specifically optimized for Woodworking, including:

• Cabinetry: Drilling precise holes for European-style “cup” hinges.

• Joinery: Creating clean, flat-bottomed holes for dowels or decorative inlays.

• Hardwood Processing: Capable of boring through Oak, Maple, and Walnut without burning the wood.

4. Machine Compatibility

The wide range of shank diameters (10 mm to 100 mm) ensures fitment for various power tools:

• Standard Drill Machines: Portable electric or cordless drills.

• Drill Presses: Ideal for ensuring 90-degree vertical precision.

Packaging & Logistics

Designed for industrial suppliers and retail hardware stores:

• Inner Box: 10 pieces, individually protected to prevent carbide chipping.

• Outer Carton: 200 pieces (20 boxes), reinforced for international shipping and bulk inventory management.

Note: Because the cutting edges are Carbide, it is recommended to use a consistent feed rate to avoid overheating, which ensures the longest possible tool life.
