Adapter SDS-plus for core drill bits with M22 thread MEGA 82985

Adapter SDS-plus for core drill bits with M22 thread MEGA 82985 is a conversion accessory that enables attachment of M22-threaded core drill bits to SDS-plus rotary hammers. It transfers rotary torque and the hammering action of SDS-plus tools to core bits with external M22 thread, allowing use of core drill bits designed for threaded chucks on SDS-plus machines for drilling into concrete and masonry.

Advantages

This SDS-plus to M22 adapter provides a secure mechanical connection and reliable torque transmission between the tool and the core bit without modifying either component. Its design maintains the hammering impact from the SDS-plus rotary hammer while supporting smooth rotation of the core bit, reducing slippage and improving drilling efficiency. The adapter is compact and intended for easy installation and removal, supporting quick changeovers on the job site.

Suitable for

• Drilling concrete and reinforced concrete with M22 core drill bits using SDS-plus rotary hammers
• Installing M22 core bits on SDS-plus machines for plumbing, electrical, and HVAC penetrations
• Construction and renovation tasks where thread compatibility between core bits and SDS-plus tools is required

Key specifications

• Compatibility: connects SDS-plus tool shanks to external M22-threaded core drill bits
• Function: transmits rotational torque and hammering action from SDS-plus rotary hammers
• Material: durable metal construction suitable for construction use
• Form factor: compact adapter designed for easy mounting and removal

How to use

Align the adapter with the SDS-plus chuck and insert it according to the rotary hammer manufacturer’s chuck engagement procedure until it locks securely. Thread the M22 core bit onto the adapter by hand until fully seated, then tighten according to the core bit manufacturer’s instructions while ensuring correct axial alignment. Operate the rotary hammer in the recommended mode (rotation with hammering) and apply steady feed pressure appropriate for the core bit and material. After use, reverse the installation steps to remove the core bit and adapter.

Usage recommendations

Use appropriate personal protective equipment, select the correct drill mode on the SDS-plus tool, and follow the maximum recommended speeds and feed pressures for the specific core bit and material. Inspect the adapter and threaded connection for wear or damage before each use and replace if any deformation or excessive wear is present.
