Drill Bit AWTools SDS‑MAX 24 x 400 x 540 mm by AWTools

The AWTools SDS‑MAX 24 x 400 x 540 mm drill bit is designed for use with SDS‑MAX rotary hammers for heavy-duty drilling in concrete, masonry and natural stone. With a 24 mm diameter and a 400 mm working length, the bit provides extended reach for deep holes while the 540 mm overall length ensures secure insertion and compatibility with standard SDS‑MAX chucks. The carbide tip and reinforced flute geometry deliver efficient dust evacuation and stable drilling performance on construction and renovation sites.

Advantages

The AWTools SDS‑MAX drill bit combines a robust shank with a precision-cut carbide head to maintain cutting efficiency and prolong tool life under repetitive loads. Its 400 mm working length allows for deeper anchoring and through-holes without compromising bit stability. Designed for SDS‑MAX systems, the bit fits securely in compatible chucks to reduce play and improve drilling control.

Suitable for

• Drilling anchor holes in concrete and reinforced concrete
• Creating through-holes in masonry and brickwork
• Drilling for plumbing, electrical and HVAC installations
• Heavy renovation and construction site drilling tasks

Key specifications

• Diameter: 24 mm
• Working length: 400 mm
• Overall length: 540 mm
• Shank type: SDS‑MAX compatible
• Recommended material: concrete, masonry, natural stone

How to use

Secure the drill bit into the SDS‑MAX chuck of a compatible rotary hammer following the tool manufacturer's instructions, ensuring a firm, fully seated connection before operation. Position the drill perpendicular to the work surface, apply steady axial pressure and allow the hammer action to advance the bit; avoid excessive force that can overload the bit and tool. Operate at the appropriate speed and impact setting for concrete or masonry and withdraw the bit periodically to clear dust and improve cooling.

Usage recommendations

Use appropriate personal protective equipment including eye and ear protection and dust extraction or a dust mask when drilling. For reinforced concrete, begin with a pilot position and consider using water sparingly only if the rotary hammer and site conditions allow; otherwise rely on periodic withdrawal to clear debris. Inspect the bit regularly for wear and replace when the carbide tip becomes rounded or when drilling performance decreases.
