## Long description

Dedra WXQ1857 SDS‑MAX 18 mm concrete drill bit is designed for use with SDS‑MAX rotary hammers and hammer drills. The bit features a dedicated carbide tip and a reinforced flute geometry that together facilitate efficient drilling in concrete and masonry. Sized at 18 mm diameter, it is suitable for creating holes for anchors, dowels and through‑holes in construction and renovation tasks where SDS‑MAX shank compatibility is required.
Advantages
The carbide tip provides improved wear resistance and maintains cutting performance when working with reinforced concrete and hard masonry. Reinforced flute design removes debris effectively, reducing clogging and heat build‑up during continuous drilling. SDS‑MAX shank ensures secure tool coupling and reliable power transfer from rotary hammers, enabling consistent drilling depth and reduced bit wobble.

How to use
Fit the Dedra 18 mm SDS‑MAX drill bit into a compatible SDS‑MAX rotary hammer according to the tool manufacturer’s instructions, ensuring the bit locks securely. Start drilling at low speed to position the hole, then apply controlled hammer action with consistent pressure. Use intermittent breaks when drilling deep holes to allow debris removal and cooling. After use, withdraw the bit while the tool is running briefly to clear dust from the flute, then stop the tool and remove the bit.
Usage recommendations
Use appropriate personal protective equipment including eye and ear protection and dust mask. For reinforced concrete, consider pre‑drilling pilot holes or use progressive drilling steps to extend bit life. Keep the bit clean and store in a dry place to prevent corrosion.
