Description
Overview:
This genuine Makita piston (OEM No: 450025-8) is a key internal component for the Makita HR4511C SDS rotary hammer drill. Built from a high‐grade metal alloy for strength and wear resistance, it forms part of the hammer mechanism that compresses air and drives the striker, helping your drill deliver consistent impact energy. When the original piston is worn or damaged, performance can drop, drilling slows, and the tool may feel uneven. Replacing it with this genuine part restores reliable operation and helps protect other internal components. Designed specifically for the HR4511C, it offers a precise fit without modification, making it suitable for professional users, facilities maintenance teams, and DIY users who need dependable performance from a heavy‐duty SDS tool.
