Discover the AC280 Lapping Compound

By combining the toughness of fused aluminum oxide with a more controlled breakdown pattern, AC280 provides consistent performance across a wide range of materials—making it an ideal choice for intermediate lapping and general-purpose finishing.

What Makes AC280 Different

  • Brown Aluminum Oxide: Abrasive Tough, durable, and slightly less friable than white aluminum oxide
  • Balanced Cutting Action: Removes material efficiently while maintaining a smoother surface profile
  • Controlled Breakdown: Fractures into less aggressive edges, reducing deep scratching and surface damage
  • Consistent Performance: Ideal for applications requiring repeatable results without over-cutting

Applications

  • General-purpose lapping and surface refinement
  • Tooling, dies, and machined components
  • Valve seats and mechanical assemblies
  • Pre-finishing before fine lapping or polishing
  • Applications requiring a balance of cut and finish

Finish Characteristics

AC280 produces a uniform, semi-smooth finish—more refined than silicon carbide compounds, but more aggressive than fine aluminum oxide or polishing compounds.

When to Choose AC280

  • You need a balance between speed and control
  • Aggressive abrasives are too harsh, but fine compounds are too slow
  • You’re preparing a surface for final finishing
  • Consistency and durability are critical

Performance Advantage

  • Provides a medium-cut, controlled finish
  • Reduces risk of aggressive gouging or uneven removal
  • Maintains cutting efficiency over extended use
  • Suitable for both roughing and intermediate finishing stages
