3M 7100091445 Collet Nut for Sanders Grinders

Product Description

The 3M 7100091445 is a replacement collet nut designed for use with 3M disc sanders, die grinders, and cut-off wheel tools. A collet nut secures the collet assembly in place, maintaining proper chuck tension and ensuring the accessory — whether a sanding disc, grinding bit, or cut-off wheel — stays locked during operation. This is an OEM-style replacement part intended to restore tool function when the original nut is worn, damaged, or lost. Installation is performed by qualified tool technicians or experienced tradespeople familiar with rotary tool service procedures.

This collet nut is used in pneumatic and electric rotary tool applications common across HVAC, sheet metal, fabrication, and general mechanical trades. It is a single-unit replacement sourced directly to match the original hardware specification for compatible 3M tool models. Consult the owners manual parts list and tool schematic to confirm this nut applies to the specific tool being serviced before ordering.
