Specification

Description

Type 11 resin bonded premium zirconium cup wheels deliver a balanced combination of power, durability, and efficiency for demanding foundry and primary metal environments. Designed for use on portable, hand-held machines such as angle grinders, these wheels excel in grinding weldments, removing casting flash, and tackling trees and risers. Zirconium alumina grain is known for its toughness and self-sharpening properties, which allow the wheel to maintain a fast cut rate while resisting premature wear. The Type 11 cup geometry provides stability and control, while the resin bond ensures strength under heavy grinding loads. The result is a versatile wheel that reduces downtime, improves productivity, and supports cleaner, more consistent finishes on ferrous metals.

Features

  • Premium Zirconium Alumina Grain—Tough and self-renewing, providing sustained cutting action even under demanding loads.
  • Type 11 Cup Design—Optimizes contact area for versatility and control when grinding welds, flash, or flat surfaces.
  • Resin Bond Construction—Strong bond matrix secures abrasive grain under heavy use, extending wheel service life.
  • High-Pressure Performance—Optimized for aggressive grinding without excessive breakdown, even on dense ferrous metals.
  • Portable Machine Compatibility—Engineered for hand-held angle grinders, offering mobility in tight or varied workspaces.

Application

Application

  • 1

    Heavy stock removal of casting flash and risers on steel or iron components.

  • 2

    Grinding down weldments in structural and fabricated assemblies.

  • 3

    Smoothing and finishing foundry trees prior to final machining or inspection.

Recommendations

  • Always operate with a well-guarded angle grinder rated for the wheel’s diameter and speed.
  • Use consistent, firm pressure—let the zirconium grain’s self-sharpening action maintain efficiency.
  • Check wheels prior to use for damage, cracks, or uneven wear.
  • Match wheel specification to the metal hardness and grinding intensity for best performance.
  • Wear full PPE (eye, face, hearing, gloves, and protective clothing) during operation to ensure safety.
