TCT annular cutter with weldon shank

Description

• Steel body: Usually made of high-quality alloy steel (e.g., M2) for strength and rigidity

• Tungsten carbide inserts: Brazed onto the cutting edges, providing exceptional hardness (up to 92 HRA) and wear resistance

• Weldon shank: Standard 3/4" (19.05mm) with two flats at 90° for secure clamping in magnetic drills

• Pilot pin: Guides the cutter for accurate centering and minimizes wandering

• Spiral flutes: Optimized for efficient chip evacuation

Key Specifications

✨ Features

1. Tungsten Carbide Cutting Edges: Exceptional hardness and heat resistance (up to 1,400°C) for cutting hard materials

2. Advanced Tooth Geometry: Often featuring triple-chip grind (TCG) with trapezoidal roughing teeth and flat finishing teeth for burr-free results

3. Spiral Flute Design: Ensures efficient chip removal, reduces friction, and prevents seizure

4. Thin-Wall Construction: Cuts only the necessary material, reducing power consumption and heat generation

5. Precision Manufacturing: Tight tolerances (typically ±0.03mm) for consistent hole quality

6. Pilot Pin System: Enables easy core ejection and maintains alignment

7. Wide Size Range: Available in various diameters and depths to suit diverse applications

⚡ Advantages

Performance Benefits

• Longer Tool Life: 5-10 times more holes per cutter compared to HSS annular cutters

• Faster Drilling: 3 times faster than conventional twist drills due to reduced material removal

• Hard Material Capability: Efficiently cuts through hardened steel (up to 50 HRC), stainless steel, cast iron, and abrasive materials

• Reduced Heat Generation: Better heat dissipation through carbide tips and spiral flutes

Cost & Efficiency Benefits

• Lower Power Consumption: Requires less torque, enabling use with lighter equipment

• Minimal Secondary Operations: Produces clean, accurate holes with burr-free edges, reducing the need for reaming or deburring

• Cost-Effective for Large Holes: Most economical for holes over 1-1/2" (38mm) in diameter and thicker materials (2"+)

• Versatile Surface Compatibility: Can drill on curved surfaces like pipes and tubing

Quality Benefits

• Consistent Precision: Maintains sharpness longer, ensuring uniform hole quality throughout its lifespan

• Reduced Vibration: Rigid construction and balanced design minimize chatter for smoother operation

• Overlapping Hole Capability: Can create overlapping holes without damage

TCT vs HSS Annular Cutters: Key Differences

Usage Tips

1. Use Cutting Fluid: Essential for extending tool life and improving hole quality, especially in stainless steel and high-tensile materials

2. Maintain Correct Speed: Follow manufacturer's recommendations (typically 50-150 RPM for steel)

3. Avoid Overheating: Allow cooling time between holes in continuous operation

4. Secure Workpiece: Use clamps or magnetic drills for stability

5. Inspect Regularly: Check for worn or damaged carbide tips to prevent poor performance or breakage
