Description
Overview:
This Brush Holder Unit is a genuine Makita OEM part (OEM No. 632E31-7) designed for the Makita HR4013C rotary hammer drill. It houses and supports the carbon brushes, providing stable electrical contact between the brushes and commutator so the motor runs reliably under load. Built from a heat‐resistant polymer with metal terminals and spring contacts, it is made to withstand vibration, heat and dust commonly found in drilling and chiselling work. Correct brush alignment and contact help reduce sparking and wear, protecting the armature and extending the life of the tool. Purpose‐made for the HR4013C, it offers precise fit and dependable performance without modification, making it suitable for both trade and DIY maintenance where consistent, safe power delivery is essential.
Key Features:
- Genuine Makita part for assured compatibility and performance on HR4013C
- Robust, heat‐resistant construction suited to heavy‐duty use
- Maintains consistent electrical contact to support smooth motor operation
- Helps minimise brush wear and reduces risk of arcing at the commutator
- Accurate seating of carbon brushes for reliable power transfer
- Easy to fit with basic tools, supporting quick routine maintenance
- Designed for demanding conditions: vibration, dust and frequent start/stop cycles
- Supports optimal life of related components (carbon brushes, armature, commutator)
Typical Applications:
Used when the original brush holder is worn, heat‐damaged, or causing intermittent power. Ideal during a motor service alongside new carbon brushes on the HR4013C used for drilling and chiselling in concrete, masonry and stone. Suitable for site maintenance teams, workshops and DIY users who need to restore stable motor performance and reduce downtime on a frequently used hammer drill.
Also known as:
Often referred to as a carbon brush carrier, brush cage, motor brush block, commutator brush carrier, or drill brush block. These terms describe the same assembly that positions the carbon brushes and keeps spring pressure on the commutator for consistent electrical contact.
