Engineered for Extreme Performance: The Science Behind Carbide Blades

Tungsten carbide saw blades represent the cutting edge of industrial tooling technology, combining tungsten carbide particles (85-94%) with a cobalt binder (6-15%) through advanced sintering processes. This creates a material with exceptional properties:

  • Hardness: 1,500-2,200 HV (Vickers)
  • Heat Resistance: Maintains cutting edge up to 900°C
  • Wear Resistance: 50-100X longer life than HSS blades

Shanghai Easydrill utilizes sub-micron carbide grades (0.5-0.8μm) with multi-layered cobalt matrices in their premium blades. This proprietary formulation achieves the critical balance between fracture toughness and wear resistance – enabling blades to withstand the extreme forces encountered in modern CNC cutting applications.


Technical Advantages Redefining Industrial Cutting

1. Unparalleled Longevity & Cost Efficiency
Laboratory testing shows:

  • Carbide blades last 8-12X longer than HSS alternatives in steel cutting
  • Reduced tool change frequency increases machine utilization by 30-45%
  • Cost-per-cut decreases by up to 60% despite higher initial investment

2. Extreme Material Capability
Easydrill’s carbide blades process materials impossible for conventional blades:

  • Hardened steels (HRC 50-65)
  • Abrasive composites (CFRP, G10, carbon ceramics)
  • Non-ferrous alloys with silicon content >18%
  • Stainless steels (304, 316L, duplex grades)

3. Precision Cutting Performance

  • Maintain dimensional tolerances within ±0.05mm
  • Surface finishes down to Ra 0.4μm achievable
  • Minimal burr formation on thin materials (<0.5mm)

Selecting Your Optimal Carbide Blade: Technical Guide

Critical Selection Parameters

Material Tooth Geometry Coating SFM Range
Mild Steel ATB 15° TiN 250-350
Stainless TCG TiCN 180-280
Aluminum Hi-ATB 20° Uncoated 3,000-5,000
Composites Triple Raker DLC 120-200

Operating Best Practices

  1. Speed Control: Never exceed manufacturer’s max SFM rating
  2. Feed Optimization: Maintain 0.06-0.12 mm/tooth chip load
  3. Coolant Strategy: High-pressure flood cooling (>15 bar) for hard metals
  4. Harmonic Management: Use variable pitch blades above 3,000 RPM
