Chuck adapter Bosch GHA FC2 Professional, length 146 mm, model 1600A003NF

Bosch GHA FC2 Professional chuck adapter (length 146 mm) converts compatible Bosch cordless drills/drivers into an SDS-plus rotary-hammer system or allows mounting of a standard chuck. It is a metal adapter designed for workshop and on-site drilling and fastening tasks where greater impact capability or quick bit changes are needed.

Advantages

The adapter provides high compatibility with the Bosch FlexiClick 5-in-1 concept, enabling fast changes between drilling, hammer drilling and screwdriving modes. A secure click-lock connection holds the adapter firmly on compatible cordless screwdrivers, while the SDS-plus holder allows quick bit swaps. Its robust metal construction and the updated impact mechanism make drilling in hard concrete easier and more efficient.

Suitable for

• Converting compatible Bosch cordless drivers to SDS-plus rotary-hammer use
• Quick interchange between chucks and SDS-plus bits on site or in the workshop
• Drilling and light hammer drilling in masonry, concrete and similar materials
• Tasks requiring a secure click-lock connection to the cordless driver

When it may not be suitable

This adapter is intended for use with compatible Bosch FlexiClick/FC2 cordless drivers; it is not suitable for non-compatible tool systems. It does not replace a dedicated large SDS-max rotary hammer for heavy demolition or continuous high-impact professional work.

Key specifications

• Adapter type: chuck to SDS-plus adapter
• Material: metal construction
• Overall length: 146 mm
• Holder type: SDS-plus quick-change holder
• Connection: click-lock interface for compatible Bosch cordless drivers

How to use

Attach the adapter to a compatible Bosch cordless screwdriver by aligning the click-lock interface and pressing until it audibly locks. Insert the required SDS-plus bit or mount a compatible chuck as needed. Use the tool according to its instructions for drilling or hammer-drilling; the adapter allows for quick bit changes and stable operation when the click-lock is engaged. Remove by releasing the lock and pulling the adapter away from the driver.

What to consider before purchase

• Verify compatibility with your Bosch cordless driver model (FlexiClick/FC2 compatible)
• Check that SDS-plus bits or the required chuck size fit your intended tasks
• Consider whether a dedicated SDS-max rotary hammer is needed for heavy demolition work

Usage recommendations

Use appropriate SDS-plus bits and observe manufacturer torque and impact limits. For prolonged hammering in very hard concrete, consider a dedicated rotary hammer. Regularly inspect the click-lock connection and the adapter surface for wear to ensure safe operation.
