Milwaukee 43-96-0091 Spring Key Kit

Product Description

The MILWAUKEE 43-96-0091 is a spring and key kit designed as a genuine replacement parts assembly for Milwaukee power tools. This kit supplies the small but critical internal components that maintain proper chuck or mechanism engagement within compatible tools. When a spring loses tension or a key wears beyond spec, tool performance and operator control degrade. Having the correct OEM-sourced kit on hand allows a technician or tool repair specialist to restore full function without sourcing components piecemeal. This kit is installed during bench-level tool service and is not intended for field repair under load.

This kit is suited for service centers, tool repair shops, and tradespeople who perform their own Milwaukee tool maintenance. It is typically used when a power tool shows signs of mechanism slippage, failure to lock, or intermittent engagement caused by spring fatigue or key wear. The exact compatible tool models are not specified in the available product data, so cross-referencing the Milwaukee parts catalog or the original tool model number is recommended before ordering.
