Drill adapter MEGA SDS-plus to threaded core bits M22 model 82986

The MEGA Drill adapter SDS-plus to threaded core bits M22 model 82986 converts an SDS-plus rotary hammer to accept M22-threaded core bits and hole saws. This accessory allows users to attach coring tools with an M22 thread to a tool with an SDS-plus chuck, expanding the range of possible drilling diameters and enabling efficient removal of material when working in masonry, concrete and similar substrates.

Advantages

The adapter provides a secure mechanical interface between an SDS-plus shank and M22-threaded coring accessories, maintaining alignment and torque transmission during rotary hammer operation. Constructed to withstand the impact and rotation forces typical for hammer drilling, it simplifies equipment setup by eliminating the need for additional conversion chucks or specialized tool bodies. The compact design keeps the tool balance close to the original rotary hammer, supporting controlled drilling and easier handling.

Suitable for

• Drilling larger diameter holes in masonry, concrete and brick with M22 core bits
• Attaching M22-threaded hole saws and coring accessories to SDS-plus rotary hammers
• Jobsite tasks where fast changeover between SDS-plus bits and M22 coring tools is required

Key specifications

• Interface: SDS-plus shank to external M22 thread
• Compatibility: Designed for use with M22-threaded core bits and hole saws
• Application area: Masonry, concrete, brick and similar substrates
• Construction: Metal alloy suitable for impact and rotational forces
• Size and weight: Compact form factor to minimize change in tool balance

How to use

Insert the adapter into the rotary hammer’s SDS-plus chuck until it locks in place according to the hammer manufacturer’s instructions. Thread the M22 core bit or hole saw onto the adapter by hand, then tighten securely using appropriate tools or by following any manufacturer guidance for torque and seating. Operate the rotary hammer in the recommended drilling mode for coring in masonry or concrete, applying steady pressure and cooling or flushing the hole if required by the coring accessory.

Usage recommendations

Inspect both the adapter and the coring accessory for wear or damage before each use. Use appropriate personal protective equipment, select correct drill speed and hammer mode for the material, and follow core bit manufacturer guidance for feed rate, lubrication or water cooling to prolong accessory life and ensure safe operation.
