HSS Annular Cutters: Precision, Efficiency, and Versatility in Metal Drilling

Technical Specifications of HSS Annular Cutters

Shanghai Easydrill’s annular cutters are engineered for durability and precision. Here’s a breakdown of their key features:

• Material: High-Speed Steel (HSS) grades M35/M42, enhanced with 5-8% cobalt for superior heat resistance.
• Coatings: Titanium Nitride (TiN) or Titanium Aluminum Nitride (TiAlN) for reduced friction and extended tool life.
• Diameter Range: 12mm to 150mm, accommodating diverse hole-sizing needs.
• Depth Capacity: Up to 75mm per cut, ideal for thick materials.
• Shank Types: Weldon, threaded, or quick-change shanks for compatibility with magnetic drills and CNC machines.
• Speed Recommendations:
  • Steel: 100–200 RPM
  • Stainless Steel: 80–150 RPM
  • Aluminum: 250–300 RPM
• Compatible Materials: Carbon steel, stainless steel, cast iron, aluminum, and non-ferrous alloys.
  

  Applications of HSS Annular Cutters

  These versatile tools are indispensable across industries:

  1. Metal Fabrication: Create precise holes for structural beams, plates, and pipelines.
  2. Construction: Drill anchor holes in steel frameworks and concrete-reinforced structures.
  3. Automotive Repair: Modify chassis, engine components, or exhaust systems efficiently.
  4. Machinery Manufacturing: Produce accurate bolt holes in heavy machinery parts.
  5. Shipbuilding: Handle thick steel plates with ease, ensuring watertight fittings.

  Advantages Over Traditional Drill Bits

  HSS annular cutters offer unmatched benefits:

  • Speed: Drill 3–5x faster than twist drills due to reduced contact area.
  • Precision: Achieve clean, burr-free holes with tight tolerances (±0.1mm).
  • Durability: Cobalt-enriched HSS and coatings withstand high temperatures, doubling tool lifespan.
  • Power Efficiency: Lower torque requirements save energy and reduce machine wear.
  • Cost-Effectiveness: Longer lifespan and minimal material waste lower long-term costs.
