Grinding wheel accessories designed for hardened steel work, promising precise shaping and efficient material removal. Metalworkers and toolmakers gain longer run times and more consistent finishes. Is sourcing map Grinding Wheel the right choice for your workshop needs?

⚡ At a Glance
  • Cutting Quality: Aggressive material removal with controlled surface roughness
  • Best for: Grinding hardened and heat-sensitive steels, cutting tools, gears, threads, thin-walled parts
  • Not ideal for: Fine polishing or finishing tasks that require much finer grit than 80

High accuracy and controlled roughness reduce abrasive consumption and extend service life. White corundum grains are small and impact-resistant, making them suitable for heat-sensitive steels.


Fast stock removal, with 80 grit aluminium oxide corundum

Granularity specified as 80 grit with an outer diameter of 75mm suits aggressive cutting and shaping. White corundum has small, uniform particles and impact resistance that produce predictable abrasion.

Rapid shaping of hardened steel and tool blanks reduces time on roughing passes. Appropriate where substantial material removal is required before finishing.

Longer service life, with high accuracy and controlled roughness

Manufacture emphasises high accuracy and consistent roughness to limit unnecessary abrasive loss during use. Lower abrasive consumption is a stated outcome of this production quality.

Fewer replacements and steadier finishing during extended workshop use. Reliability suits frequent grinding tasks.

Precise tool shaping, with cup wheel profile and specified mounting dimensions

Cup abrasive form with outer diameter 75mm, inner diameter 56mm, hole diameter 20mm and height 32mm provides stable contact for forming operations. Application guidance lists cutting tools, gears, threads and thin-walled parts as intended uses.

Secure mounting on compatible grinders leads to consistent profiles on tools and components. Well suited to precision shaping tasks common in toolmaking.
