Description

The Karbosan Zirconia ZWR51 Topsize Fibre Disc represents the next level in heavy-duty zirconium abrasive discs, engineered for demanding industrial grinding and surface preparation applications.

PRODUCT OVERVIEW
The Karbosan Zirconia ZWR51 Topsize Fibre Disc is a high-performance abrasive designed for professional metalworkers, fabricators, and industrial maintenance teams. Featuring an abrasive zirconia grain on a durable vulcanised fibre backing with a specialised Topsize coating to help absorb heat, the ZWR51 excels in tough grinding tasks on a wide range of ferrous materials. Its advanced construction ensures reliable cut rates and extended disc life even under heavy use.

KEY BENEFITS
• Heat-absorbent Topsize coating to reduce heat build-up during grinding.
• Premium zirconia abrasive grain for aggressive stock removal and long disc life.
• Vulcanised fibre backing for strength and durability under high pressure.
• Ideal for stainless steel (Inox), high alloy steel, heat resistant steels and cast iron.
• Consistent performance across the disc life with reduced loading and clogging.
• Professional quality for workshop and industrial environments.

RECOMMENDED APPLICATIONS
Perfect for surface preparation, weld blending, deburring, edge finishing, and stock removal on tough metal surfaces. The ZWR51 Topsize disc is especially suited to applications requiring high material removal rates combined with controlled heat management prior to finishing or painting. Compatible with angle grinders and fixed sanding machines in fabrication shops, manufacturing, construction, and heavy maintenance operations.

Typical sizes include multiple diameters from 100 × 16 mm up to 230 × 22.23 mm, with grit options from P24 up to P120 as standard, depending on your application needs.

STORAGE & HANDLING
Store in a flat, dry location away from moisture, extreme temperatures, and direct sunlight. Before use, check compatibility with your grinder and ensure the disc is free from defects. Do not operate above the stated maximum RPM. Always wear appropriate personal protective equipment (PPE) including eye, hand, hearing, and respiratory protection. Follow the safety and machine manufacturer’s guidelines throughout use.
