Description
Overview:
This Cushion Rubber is a genuine Makita part designed for selected cordless hammer drills, including the BHR242 and BHR243. Manufactured from durable black rubber, it sits within the hammer mechanism to absorb impact, reduce vibration, and help protect internal components. By cushioning the blow action, it supports smoother drilling and chiselling, maintains tool control, and helps extend service life. Supplied under Makita MPN 424473-7, it offers the correct fit and hardness for the specified machines, ensuring reliable performance after routine maintenance or repair. Suitable for users who need to keep their Makita rotary hammers working efficiently on concrete, brick, and masonry tasks, as well as for those maintaining compatible variants in the DHR24x and DHR243 ranges.
