3M 7100290243 Quick-change Disc 3 in Ceramic Extra Coarse

Product Description

The 3M 7100290243 is a 3-inch diameter quick-change abrasive disc built for metal fabrication and finishing work. It uses a precision shaped ceramic abrasive grain in a non-woven, unitized wheel construction rated for a maximum of 18,100 RPM. The extra coarse grade makes it well suited for aggressive deburring and grinding applications. The quick-change attachment system allows fast disc swaps without tools, reducing downtime during production runs. Metalworkers, fabricators, and maintenance technicians are the primary users of this disc type.

This disc is designed for deburring and grinding on metal surfaces. The non-woven construction provides a consistent cut throughout the life of the disc, as the abrasive grain is distributed through the entire wheel thickness rather than applied only to the surface. It is commonly used on angle grinders and die grinders equipped with a compatible quick-change mandrel. Applications include weld cleanup, edge deburring, and surface conditioning on ferrous and non-ferrous metals in both shop and field environments.

Key Features

• Precision shaped ceramic abrasive grain for consistent, aggressive material removal
• Extra coarse grade suited for deburring and grinding tasks
• Non-woven unitized wheel construction delivers uniform performance throughout disc life
• 3-inch diameter fits standard quick-change mandrel systems
• 18,100 maximum RPM rating for use with high-speed grinders
• Non-woven gray backing provides flexibility during surface contact

Compatibility

Designed for use with quick-change mandrel systems compatible with 3-inch non-woven unitized discs. Verify mandrel type and RPM rating of the tool before installation to ensure a safe, secure fit.

Installation Notes

Installation is performed by metalworkers and fabricators using a compatible quick-change mandrel mounted to an angle grinder or die grinder. Confirm the tool spindle speed does not exceed the 18,100 RPM maximum rating of the disc before use. Inspect the disc for damage prior to each use and replace if any cracking, tearing, or deformation is present. Always wear appropriate eye protection and follow applicable workplace safety standards when operating grinding equipment.
