Disco de fibra abrasiva 3M Cubitron II 115 x 22 mm, grão 36+, pack de 25

3M Cubitron II abrasive fiber discs, 115 x 22 mm, grit 36+, pack of 25 are engineered for fast material removal and consistent performance on metal surfaces. These discs use 3M's Cubitron II ceramic grain technology to provide an efficient cutting action with extended life compared to conventional abrasives. Sized for angle grinders with a 22 mm arbor, the discs are balanced for power tools and designed to resist glazing during heavy-duty grinding tasks.

Advantages

The ceramic-cutting grain geometry delivers high cut rates and longer service life, reducing the number of disc changes. The fiber backing offers robust support for controlled stock removal and improved durability under pressure. The uniform grit distribution helps maintain consistent surface finish while reducing heat build-up. Packaged in a set of 25, the discs provide cost-effective replenishment for busy workshops and industrial environments.

Suitable for

• Weld removal and seam blending on steel and stainless steel
• Deburring and edge preparation
• Surface preparation before painting or coating
• Rapid stock removal on castings and fabricated metal parts
• Use with 115 mm angle grinders having a 22 mm arbor

How to use

Select an appropriate 115 mm angle grinder with a 22 mm arbor and ensure the tool is switched off and unplugged before mounting the disc. Fit the disc securely according to the grinder manufacturer's instructions, check for any visible damage, and wear recommended personal protective equipment including eye and face protection, gloves, and hearing protection. Start grinding with light-to-moderate pressure, allowing the Cubitron II grain to cut efficiently; avoid excessive pressure that can overload the tool or cause premature wear. Replace discs when the cutting performance decreases or the disc shows signs of damage.

Recommendations

For best results, use these 36+ grit discs for aggressive material removal and follow safety guidelines for grinding operations. Store discs in a dry, cool place and rotate stock to prevent prolonged exposure to humidity. Match disc speed rating to the grinder's RPM and avoid side-loading beyond the disc's intended application to maintain performance and safety.
