Drill bit AWTools AW43511 — replacement drill bit, model AW43511

AWTools AW43511 replacement drill bit is a carbide-tipped accessory designed for use with compatible hammer drills and rotary hammers. Constructed from 40CR alloy steel with a YG8C carbide cutting tip, the AW43511 is intended for general drilling in hard materials such as concrete, reinforced concrete, rebar and brick. The bit features a centering point with a 130° point angle and a grooved SDS+ shank to ensure secure seating and reliable transfer of impact power.

Advantages

The combination of 40CR alloy steel body and YG8C carbide tip increases wear resistance and extends tool life under heavy-duty use. A double spiral flute improves removal of drilled material, reduces overheating and lowers vibration during operation. Four cutting edges produce clean, smooth holes and help minimise the risk of jamming when encountering rebar. The grooved SDS+ shank design prevents the bit from falling out and ensures stable performance with compatible chucks.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Drilling through masonry such as brick and block
• Punching through rebar and other mixed hard materials
• Replacement or spare bit for workshops and on-site maintenance

Key specifications

• Material: 40CR alloy steel body with YG8C carbide tipped cutting edge
• Point geometry: centering point with 130° point angle
• Flute design: double spiral for efficient chip evacuation
• Cutting edges: four cutting edges for smoother holes
• Shank type: grooved SDS+ shank for secure retention
• Application: designed for drilling concrete, reinforced concrete, rebar and masonry
• Compatible tool types: hammer drills and rotary hammers

How to use

Install the AWTools AW43511 into the SDS+ chuck of a compatible hammer drill or rotary hammer following the tool manufacturer’s mounting instructions. Select an appropriate drilling speed and engage hammer action when penetrating concrete or reinforced materials. Apply steady pressure without forcing the bit; allow the combination of impacts and rotation to advance the cut. Periodically withdraw the bit to clear debris and allow cooling. Replace the bit if the carbide tip becomes chipped or shows excessive wear.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection and dust extraction or a vacuum when drilling masonry and concrete. For prolonged drilling or large-diameter holes, allow the bit to cool between passes and consider using water cooling only if recommended by the drill manufacturer. Store the AW43511 bit in a dry place to prevent corrosion of the steel body.
