Supplied in packs of five, it is suitable for professionals and skilled tradespeople who need improved productivity when working on fabricated stainless steel components.

Advantages

The Prisma ceramic fibre construction delivers accelerated grinding speed compared with conventional discs while preserving surface quality. The flat centre shape helps achieve uniform contact on workpieces, and the disc is designed for use with X-LOCK compatible angle grinders for quick mounting. The pack format (5 discs) offers practical replacement intervals and better value for continuous workshop use.

How to use

Avoid excessive force; let the abrasive remove material to prevent overheating or premature wear. Replace the disc when abrasive performance declines.

Recommendations

The disc is intended for professional use on stainless steel and thin steel; use appropriate personal protective equipment (eye, ear, respiratory and hand protection), secure the workpiece, and follow all safety instructions from both the grinder and disc manufacturers.
