3M 7100263661 Quick-change Disc 5 in Fine Ceramic Tn

Product Description

The 3M 7100263661 is a 5-inch diameter quick-change abrasive disc from the PN-DN series, designed for right-angle grinders using a Type TN attaching system. Constructed with a precision shaped ceramic abrasive bonded to a non-woven backing, this fine-grade disc delivers consistent material removal and surface conditioning in a single tool. It weighs approximately 0.056 pounds and reaches a maximum operating speed of 12,000 RPM. Installers, fabricators, and surface preparation technicians use this disc where repeatable, controlled results are required across a wide range of surface finishing tasks.

This disc is suited for metalworking and general fabrication environments where multiple surface operations are performed in sequence. Its non-woven green construction and fine grade make it appropriate for light-to-medium duty work including deburring, radiusing, finishing, cleaning, blending, and refining metal surfaces. It mounts on right-angle grinders equipped with a Type TN quick-change interface, allowing fast disc swaps without additional tooling. The PN-DN series is intended for professional-grade use in shops and field fabrication settings.

Key Features

• Precision shaped ceramic abrasive for consistent cut rate and extended disc life
• Non-woven backing provides conformability to contoured and flat surfaces
• Type TN quick-change attaching system for tool-free disc changes
• Fine grade suitable for deburring, finishing, blending, radiusing, cleaning, and refining

Compatibility

Designed for use with right-angle grinders equipped with a Type TN quick-change interface. Verify that the grinder spindle speed does not exceed the 12,000 RPM disc rating before installation.

Installation Notes

Installation should be performed by trained metalworking or fabrication personnel familiar with abrasive disc safety practices. Ensure the grinder is disconnected from power before mounting or removing the disc. Confirm the Type TN backing pad is clean and undamaged, and that the grinder's no-load RPM does not exceed the disc's 12,000 RPM maximum rating. Always wear appropriate personal protective equipment including eye protection and gloves when operating abrasive discs.
