Drill bit AWTools AW43730, weight 840 g

The AWTools AW43730 drill bit is a heavy-duty exchangeable bit designed for use with compatible hammer drills and rotary hammers. Made of high-quality alloy steel and fitted with a tungsten carbide tip, this 840 g bit combines durability with precision. Its wide flute, double spiral design and 130° self-centering point enable efficient material removal and accurate positioning without a separate pilot hole. The grooved SDS‑MAX shank secures the bit in the tool and reduces the risk of accidental release during demanding drilling tasks in masonry and stone materials.

Advantages

The combination of a tungsten carbide cutting tip and two-cutting-edge geometry provides reliable cutting performance and extended service life when working in abrasive materials. The double spiral flute improves chip evacuation and cooling, lowering the risk of overheating and reducing vibration transfer to the tool. The 130° self-centering point speeds up setup by allowing accurate starts without a pilot hole, while the SDS‑MAX grooved shank ensures secure retention and quick bit changes in compatible drills.

Suitable for

• Drilling holes in masonry and concrete
• Working in granite and natural stone
• Drilling through brick and ceramic tiles
• Use with hammer drills and rotary hammers for construction and workshop tasks

How to use

Install the AWTools AW43730 into a compatible SDS‑MAX holder until it locks securely. Select the hammer or rotary mode on the drill for hard materials such as concrete or stone; for ceramic tiles, start with low impact or rotary-only mode to minimize chipping. Position the self-centering point at the desired spot and apply steady axial pressure while keeping the drill aligned. Use intermittent drilling for deep or large-diameter holes to allow cooling and to clear debris from the flute. After completing the hole, withdraw the bit while the tool is running briefly to clear remaining dust.

Usage recommendations

Wear appropriate personal protective equipment including safety glasses, hearing protection and a dust mask. Secure the workpiece where possible, and monitor the bit for wear—replace the bit if the carbide tip becomes chipped or dull to maintain efficient and safe drilling performance.
