Description
Overview:
The Slide Sleeve for Makita DHR400 is a genuine Makita OEM component (MPN 454347-8) designed to restore the smooth sliding action of the hammer's front assembly. Precision-moulded from a tough engineering polymer for long service life, it works as a low-friction guide and wear surface, helping to keep the tool holder aligned and shielding internal parts from grit. Built for high-impact SDS-MAX rotary demolition hammers, it is specifically matched to the Makita DHR400 and HR4013C. Replacing a worn or cracked sleeve prevents sticking, excess play and premature wear, helping your hammer drill maintain consistent performance under site conditions. Suitable for routine servicing or repair in workshops and on site, this sleeve supports reliability without altering the tool's original design.
