## Long description

AWTools SDS Max 40×400×540 mm drill bit (model AW43879) is a heavy-duty masonry bit engineered for rotary hammers with an SDS Max chuck. With a 40 mm diameter, 400 mm working length and 540 mm overall length, this drill bit provides extended reach for deep holes in concrete, brick and similar materials. The square shank design improves torque transfer and secures the bit in the tool during demanding drilling tasks.
Advantages
The square shank ensures a positive mechanical coupling with the SDS Max holder, reducing slippage under high load and improving drilling efficiency. Its long working length allows access to recessed areas and deeper anchoring or installation points without the need for extensions. The bit is designed for durable performance in masonry and concrete, providing consistent cutting action and reliable hole quality in professional and heavy-duty applications.
Suitable for
Drilling deep holes for anchors and dowels in concrete and masonry
Installing through-feed sleeves and conduit in walls
Professional construction and renovation work requiring extended reach
Heavy-duty drilling tasks with SDS Max rotary hammers
Key specifications
Tip diameter: 40 mm
Working length: 400 mm
Overall length: 540 mm
Shank type: square shank compatible with SDS Max chucking systems
Intended material: concrete, masonry and similar mineral substrates
How to use
Select an SDS Max-compatible rotary hammer and secure the bit in the chuck according to the tool manufacturer's instructions, ensuring the square shank engages fully. Mark the drilling position, start at low speed to establish the pilot contact, then apply steady pressure while running the hammer in rotary or rotary-plus-percussion mode as appropriate for the substrate. Withdraw occasionally to clear dust from deep holes and allow the bit to cool. Use correct personal protective equipment such as eye protection, hearing protection and dust control measures.
Usage recommendations
For long-term bit life and consistent hole quality, use the bit with SDS Max rotary hammers rated for heavy-duty masonry work, avoid excessive lateral force, and clean flutes periodically when drilling deep holes. For drilling reinforcement or extremely hard areas, consider using a properly rated carbide-tipped or specialized bit and follow recommended feed pressures and rpm ranges from the rotary hammer manufacturer.
