Tungsten Carbide Tip Annular Cutters: Power, Precision, and Longevity in Metal Drilling

Technical Specifications of Tungsten Carbide Tip Annular Cutters

Shanghai Easydrill’s annular cutters are engineered for extreme durability and efficiency. Key features include:

• Material:

• Body: High-strength alloy steel for structural integrity.

• Tip: Tungsten carbide (WC) inserts with 90–94 HRA hardness for wear resistance.

• Coatings:

• TiN (Titanium Nitride): Reduces friction and extends tool life.

• TiAlN (Titanium Aluminum Nitride): Enhances heat resistance (up to 800°C).

• Diameter Range: 14mm to 160mm, suitable for diverse industrial needs.

• Depth Capacity: Up to 85mm per cut, ideal for thick steel plates and cast iron.

• Shank Types: Weldon, threaded, or quick-change shanks for compatibility with magnetic drills, CNC machines, and portable rigs.

• Speed Recommendations:

• Carbon Steel: 150–250 RPM

• Stainless Steel: 100–180 RPM

• Hardened Steel/Alloys: 80–120 RPM

• Compatible Materials: High-strength steel, stainless steel, cast iron, titanium, and abrasive alloys.

Applications of Tungsten Carbide Tip Annular Cutters

These robust tools excel in industries requiring precision in harsh conditions:

1. Heavy Machinery Manufacturing: Drill bolt holes in excavator arms, bulldozer frames, and crane components.

2. Mining Equipment: Penetrate hardened steel in rock drills, conveyor systems, and crushers.

3. Aerospace: Create precise holes in turbine blades and engine parts made of heat-resistant alloys.

4. Oil & Gas: Drill through thick pipelines, flanges, and offshore platform structures.

5. Construction: Cut anchor holes in reinforced steel beams and pre-stressed concrete.

6. Railway Industry: Maintain rails and rolling stock with high-speed, low-wear drilling.

Advantages Over HSS Annular Cutters

Tungsten carbide tip annular cutters offer transformative benefits:

• Extended Tool Life: Carbide tips last 5–8x longer than HSS, reducing downtime and replacement costs.

• Higher Cutting Speeds: Maintain efficiency in hardened materials without compromising precision.

• Superior Wear Resistance: Ideal for abrasive or high-temperature applications.

• Cost-Effectiveness: Lower long-term costs despite a higher initial investment.

• Versatility: Tackle materials up to 60 HRC hardness, including tool steel and Inconel.

• Cleaner Cuts: Reduced burring and smoother finishes minimize post-processing.
