Drill bit RAWLPLUG SDS‑MAX 28 mm RT‑MAXT‑28/540 for hammer drills, 28mm diameter

RAWLPLUG SDS‑MAX 28 mm RT‑MAXT‑28/540 is a heavy‑duty drill bit designed for SDS‑MAX hammer drills and rotary hammers. With a 28 mm diameter and a length suited for common construction tasks, this bit is intended for drilling into concrete, masonry and similar mineral materials. The SDS‑MAX shank provides secure engagement in compatible chucks and optimizes power transfer during hammering, enabling effective large‑diameter hole production for anchors, sleeves and through‑holes.

Advantages

The drill bit combines a large 28 mm cutting diameter with the SDS‑MAX connection to ensure stable mounting and efficient energy transmission in hammer drills. Its design focuses on reliable drilling in reinforced concrete and masonry, reducing wobble and improving hole accuracy. The robust construction increases service life under frequent use in professional and construction environments.

Suitable for

• Drilling anchor and sleeve holes in concrete and masonry
• Creating through‑holes for installations and piping
• Professional construction and renovation projects requiring large‑diameter holes
• Use with SDS‑MAX hammer drills and rotary hammers

Key specifications

• Drill diameter: 28 mm
• Shank type: SDS‑MAX
• Intended materials: concrete, masonry and similar mineral substrates
• Application: hammer drilling with rotary impact action

How to use

Fit the drill bit into an SDS‑MAX compatible hammer drill following the tool manufacturer's insertion procedure until it locks securely. Select the hammer drilling mode on the tool and start at low speed to position the bit, then apply steady pressure while maintaining the drill perpendicular to the surface. For deep or long holes, withdraw periodically to clear debris and allow cooling. Use appropriate personal protective equipment including eye, ear and respiratory protection when drilling.

Usage recommendations

Use the bit with a hammer drill rated for SDS‑MAX bits and match drilling speed and pressure to the material. For reinforced concrete, use controlled feed and clear dust frequently; for precise anchor holes, verify depth with a depth stop. Store the bit dry and inspect cutting edges before use to maintain performance.
