Makita 158285-3 Tool Holder Assembly HR2811F

Product Description

The MAKITA 158285-3 is a complete tool holder assembly designed as a direct OEM replacement component for the Makita HR2811F rotary hammer. The tool holder is the front-end chuck mechanism responsible for securing drill bits and chisels during operation. It locks tooling in place under the repeated impact and rotation forces generated by rotary hammer use. Licensed technicians and power tool repair specialists install this part during routine maintenance or when the existing holder shows wear, slippage, or damage that compromises bit retention and operator safety.

This assembly is intended for service and repair of the Makita HR2811F rotary hammer, a compact SDS-plus class tool used in light demolition, concrete drilling, and masonry work across residential and commercial job sites. The complete assembly format means all sub-components of the holder come together as a single serviceable unit, simplifying the repair process and reducing diagnostic time for technicians.

Key Features

• Complete assembly replacement — all holder sub-components included as one unit
• OEM Makita part number 158285-3 ensures direct fitment for the HR2811F model
• Designed to withstand repeated impact and rotational stress of rotary hammer operation

Compatibility

The MAKITA 158285-3 tool holder assembly is compatible with the Makita HR2811F rotary hammer as specified by the manufacturer part designation.
