Drill bit RAWLPLUG SDS‑MAX 22 mm RT‑MAXT‑22/540 for hammer drills, SDS‑MAX shank

RAWLPLUG SDS‑MAX 22 mm RT‑MAXT‑22/540 is a rotary‑hammer drill bit with an SDS‑MAX shank designed for creating 22 mm diameter holes in concrete, masonry and natural stone. The bit is manufactured for use with SDS‑MAX compatible hammer drills and is suitable for heavy‑duty drilling tasks that require repeated impact and high torque. It is intended for drilling through‑holes, anchor and dowel installation, and general construction work where a durable, high‑performance masonry bit is required.

Advantages

The SDS‑MAX shank provides secure tool retention and rapid bit changes on compatible rotary hammers. The 22 mm cutting diameter delivers accurately sized holes for common anchors and through‑fastenings, while the robust design withstands high impact loads and prolonged drilling cycles. The bit’s geometry is optimised for effective dust evacuation and efficient material removal, reducing clogging and maintaining drilling speed during continuous use.

Suitable for

• Drilling 22 mm holes in concrete for anchor and dowel installation
• Through‑holes in masonry and natural stone
• Heavy‑duty construction and renovation tasks with SDS‑MAX rotary hammers
• Applications requiring high impact resistance and reliable bit retention

Key specifications

• Diameter: 22 mm
• Shank type: SDS‑MAX
• Intended materials: concrete, masonry, natural stone
• Use case: rotary‑hammer drilling with impact action
• Typical hole type: through‑holes and anchor/drill holes

How to use

Insert the SDS‑MAX shank into the rotary hammer’s chuck until it locks. Select the hammer drilling mode on the tool and position the bit perpendicular to the work surface. Start drilling at low speed to establish the pilot point, then apply steady pressure while allowing the hammer action to perform the cutting. Periodically withdraw the bit to clear dust and debris, especially when drilling deep holes. For through‑holes, ensure both sides of the material are supported to prevent breakout.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection and dust mask. Match drill speed and feed pressure to the material and tool specifications; excessive force may reduce bit life. For faster debris removal in deep holes, use intermittent retraction or an extraction system where available. Store the bit in a dry place to prevent corrosion and inspect regularly for wear; replace the bit when cutting efficiency or hole accuracy declines.
