Description
Overview:
The Conical Comp Spring 234049-0 is a genuine Makita OEM component used in rotary hammer drills, including the HR3210C and HR3210FCT. This tapered compression spring is engineered to maintain the correct preload within the hammer drill mechanism so the tool runs smoothly under repeated impact. Manufactured from tough, high-grade spring steel, it resists fatigue and deformation in demanding site conditions. Replacing a tired or distorted spring restores consistent operation, helping to reduce vibration, misfeeds, and intermittent hammering. Suitable for professional and DIY maintenance, it is a direct-fit part designed to meet Makita's specifications for reliable performance and long service life in concrete drilling and light chiselling tasks.
Key Features:
- Genuine Makita OEM spring for assured fit and function
- Conical design seats correctly and maintains even compression through the stroke
- High-strength spring steel resists wear and fatigue under repeated impacts
- Helps restore smooth hammering and drilling operation when an original spring is worn
- Stable, consistent tension supports reliable mode engagement and feed pressure
- Direct replacement for the specified Makita models to minimise downtime
- Suitable for routine servicing and preventative maintenance schedules
- Compact form factor for easy placement within the assembly during re-fit
Typical Applications:
Used during service or repair of Makita rotary hammer drills to restore correct mechanism preload. Ideal when the tool exhibits weak hammer action, inconsistent drilling, or poor mode engagement. Suitable for construction, renovation, M&E installation, and general maintenance where anchors, fixings, and channelling in masonry and concrete are common.
