Drill Bit AWTools SDS‑MAX 18 x 400 x 540 mm for masonry and concrete, AWTools

SDS‑MAX drill bit AWTools 18 x 400 x 540 mm is designed for hammer drills with an SDS‑MAX shank and intended for drilling deep holes in concrete, reinforced concrete and masonry. The bit has a 400 mm working length and 540 mm overall length, allowing installation of anchors, through‑holes and other construction openings where a long reach is required. The carbide tip and flute geometry are optimized for effective dust removal and sustained drilling performance in dense materials.

Advantages

The AWTools SDS‑MAX bit provides reliable penetration in hard substrates thanks to a reinforced shank connection and a wear‑resistant carbide tip. Its extended working length reduces the need for extensions when drilling deep anchor holes. The flute profile is engineered to evacuate debris efficiently, supporting consistent drilling speed and reducing binding. The bit is compatible with standard SDS‑MAX hammer drills, offering straightforward installation and stable operation.

Suitable for

• Drilling anchor holes in concrete and reinforced concrete
• Creating through‑holes for pipes and conduits
• Masonry drilling for fixing systems and structural fastenings
• Construction and renovation tasks requiring deep, straight holes

Key specifications

• Type: SDS‑MAX masonry/concrete drill bit
• Diameter: 18 mm
• Working length: 400 mm
• Overall length: 540 mm
• Tip material: carbide tip for improved wear resistance
• Shank interface: SDS‑MAX compatible
• Application materials: concrete, reinforced concrete, masonry

How to use

Fit the SDS‑MAX shank securely into the hammer drill’s chuck until it locks. Select an appropriate rotational speed and hammer setting according to the drill manufacturer’s recommendations for 18 mm bits in concrete. Begin drilling with light pressure to establish a centering point, then apply steady force while allowing the hammer action and bit geometry to do the work. Periodically withdraw the bit to clear accumulated dust and check progress; for deep holes, retract fully at intervals to improve debris removal and reduce heat buildup.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection and a dust mask. For reinforced concrete, monitor bit condition and replace when carbide wear reduces drilling efficiency. Use water extraction or a vacuum dust collection system where required by site regulations to control silica dust.
