## Long description

AWTools AW SDS MAX 28 x 400 x 540 mm Square is a rotary-hammer drill bit with an SDS‑MAX shank, a 28 mm cutting diameter, a 400 mm working length and a 540 mm overall length. The bit features a square profile tip specifically shaped for effective drilling in concrete and masonry. It is designed for use with SDS‑MAX compatible breakers and rotary hammers for professional and home improvement tasks such as drilling anchor holes, through‑holes and installing heavy-duty fasteners.
Advantages
The SDS‑MAX shank provides secure retention and quick bit changes in compatible rotary hammers. The square profile tip improves material removal and reduces jamming when drilling into reinforced concrete and dense masonry. With a long working length of 400 mm, the bit enables deep-hole drilling for anchors and through-connections while the overall length offers comfortable tool handling. The carbide tip and robust steel body combine to provide durability under repeated impact loads.
Suitable for
Drilling anchor holes in concrete and reinforced concrete
Creating through‑holes for pipes, conduits and fixings
Installation of heavy-duty fasteners and mechanical anchors
Professional construction and renovation work with rotary hammers
DIY projects that require deep drilling in masonry
Key specifications
Shank type: SDS‑MAX compatible
Cutting diameter: 28 mm
Working length: 400 mm
Overall length: 540 mm
Tip profile: square
Intended materials: concrete, masonry, reinforced concrete
How to use
Install the bit into an SDS‑MAX compatible rotary hammer according to the tool manufacturer's instructions, ensuring the shank locks securely. Mark the drilling position, start the drill at low speed to establish the position, then apply steady forward pressure and use hammer action for effective penetration. Clear the hole periodically of debris to maintain drilling efficiency and prevent overheating. After completing the hole, withdraw the bit while the tool is running briefly to expel dust.
Usage recommendations
Use appropriate personal protective equipment such as safety goggles, hearing protection and dust mask. Select correct drill mode (hammer + rotation) and avoid excessive side loads. For reinforced concrete, consider pre‑drilling pilot holes or using a bit specifically rated for high rebar content. Replace the bit if cutting performance decreases or visible damage appears.
