Engineered as an OEM-grade replacement for Milwaukee M12 2456-20/2457-20 cordless lithium-ion ratchets, this impact-resistant rubber protective boot combines industrial durability with ergonomic precision. Its thickened, non-slip rubber shell absorbs 70%+ shock energy during high-torque operations, shielding both 3/8" and 1/4" drive tools from drops, scratches, and surface damage. The form-fitting design contours seamlessly to your wrench body without hindering trigger access or adding bulk, while precision-molded grooves ensure tool ventilation and heat dissipation. Tested under rigorous workshop conditions, the tear-resistant material withstands oil exposure and repeated impacts, extending your Milwaukee ratchet's lifespan through daily wear protection.
