Genuine 2 Speed Change Ring fits BHP451 8444D Drill

The Makita 419558-2 Speed Change Ring is a genuine OEM replacement selector component for Makita cordless combi drills, designed to restore accurate gearbox speed selection on the BHP451 and 8444D platforms. Worn or damaged speed change rings are a common cause of imprecise gear selection on high-use cordless drills. This genuine Makita part allows contractors and tradespeople to return their drill to factory performance without the cost of a full tool replacement. It is equally suited to routine preventative maintenance as it is to direct repair of a failed component. Manufactured from a durable polymer and engineered to an exact fit, the 419558-2 interfaces correctly with the drill's transmission to deliver crisp, positive speed selection across both gear ranges. No modification is required during installation, and the part can be fitted using standard hand tools. This is a practical solution for trade professionals looking to extend the working life of their Makita BHP451 or 8444D drill and maintain consistent drilling and driving performance on site.
