A workshop-grade abrasive for shaping and finishing hardened steels, promising accurate removal with consistent surface quality. Confidence for toolmakers and metalworkers who need predictable results from each pass. Is the sourcing map Grinding Wheel the right choice for precision jobs and regular shop use?
⚡ At a Glance
- • Cutting Quality: High material removal with a controlled finish thanks to uniform white corundum grains
- • Best for: Grinding hardened and heat-sensitive steels, shaping cutting tools, gears and threads
- • Not ideal for: Delicate finishing on soft metals where minimal stock removal is required
A 75mm cup wheel in 100 grit, made from white corundum for impact resistance and uniform wear. Designed for grinding hardened, high carbon and alloy steels used in tool and gear work.
Fast material removal - with 100 grit white corundum grains
White corundum (aluminium oxide) uses small, uniform abrasive particles that bite into steel consistently, accelerating stock removal while maintaining surface control. The 100 grit rating balances cut rate and finish quality for many workshop tasks.
Quicker shaping of hardened parts without wildly rough surfaces, so fewer passes are needed to reach the desired profile.
Durable performance - thanks to uniform particle size and impact resistance
Corundum particles resist fracturing under impact and wear evenly due to their uniform size, which reduces abrasive consumption. The wheel construction emphasises high accuracy and efficiency to prolong service life.
Longer-lived wheels mean fewer changes during a shift and lower material replacement frequency for busy shops.
Safer, more predictable use - with recommended inspection and break-in procedure
Pre-use appearance and sound checks help detect damage, while idling the wheel for more than a minute after installation allows mounting stresses to settle. The manufacturer also advises dry, flat storage and avoidance of drops or impacts.
Following simple checks and a short run-in reduces the risk of failure and helps maintain consistent cutting behaviour in everyday use.

❓ Frequently Asked Questions
Q: What materials is the wheel suitable for?
A: Suitable for hardened and heat-sensitive steels, including high carbon and alloy steels, and recommended for cutting tools, gears and threads.
Q: What size arbor does it fit?
A: The wheel has a 20mm inner diameter, intended for grinders with a compatible 20mm arbor bore.
Q: Are there any special checks before using the wheel?
A: Carry out an appearance and sound inspection before installation and run the wheel idling for over one minute when newly fitted or after intermittent use.
🏆 Our Verdict
Ideal for metalworkers and toolmakers who need reliable, repeatable grinding on hardened steels. The combination of 100 grit white corundum and uniform particle structure gives predictable cutting performance and extended wheel life. While initial choice should match the specific grinder arbor and task, long-term value comes from reduced abrasive consumption and consistent results.
