The Milwaukee Rubber sleeve is a perfect replacement for this impact wrench M18ONEFHIWF1. This accessory combined with the power tool would be mostly used by trade professionals and some home DIY users. The rubber sleeve is a lightweight, form-fitting design that protects the tool and worksurface. When the sleeve is securely on the tool it is designed to not dramatically increase any weight to the tool. It should not be used on or near live electrical circuits. Using it with any other product, other than the advised products, may cause damage to the tool and may void tool warranty. Supplied as a single unit.
