Description
Overview:
The Spring Guide for Makita hammer drills is a genuine Makita component designed to keep the spring mechanism aligned and moving smoothly during operation. Made from robust, precision‐machined metal, it sits within the hammer mechanism to guide the spring and help maintain consistent impact performance under heavy use. This reduces the chance of binding or uneven wear on surrounding parts. It is intended for Makita rotary hammer drills such as the HR4511C and HR5211C, and is supplied under Manufacturer Part Number (MPN) 345804-6. As an OEM replacement, it restores correct function when the original guide has worn or been damaged, helping extend the service life of the tool and supporting reliable performance on site or in the workshop.
