Drill bit AWTools AW43526 – AWTools AW43526 replacement drill accessory

AWTools AW43526 replacement drill accessory is a carbide-tipped drill bit designed for drilling in concrete, reinforced concrete, rebar, brick and other hard materials. Constructed from 40CR alloy steel with a YG8C carbide cutting tip and a grooved SDS+ shank, this bit is intended for use with compatible hammer drills and rotary hammers for general-purpose and workshop drilling tasks.

Advantages

The YG8C carbide tip and four cutting edges provide clean, smooth holes while reducing the risk of jamming when encountering rebar. A 130° centering point ensures accurate starts and improved control. Double spiral flutes enable efficient dust and debris evacuation, lower operating temperatures and reduce vibration during use. The grooved SDS+ shank secures the bit in the chuck to prevent accidental release during hammering operations.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Making penetrations through brick and masonry
• Puncturing or enlarging holes that may encounter rebar
• Use with hammer drills and rotary hammers for construction and renovation tasks

Key specifications

• Material: 40CR alloy steel body with YG8C carbide tipped blade
• Point angle: 130° centering point for precise starts
• Cutting geometry: four cutting edges for smooth hole walls
• Flute design: double spiral for efficient debris removal and reduced heat
• Shank type: grooved SDS+ shank to prevent accidental release
• Applications: suitable for concrete, reinforced concrete, rebar, brick and other hard materials
• Compatible tools: hammer drills and rotary hammers

How to use

Select a compatible hammer drill or rotary hammer that accepts SDS+ shanks and install the AWTools AW43526 bit according to the tool manufacturer's instructions. Start drilling at low speed to establish the centering point, then apply steady pressure and use the hammer function for dense materials as needed. Maintain a perpendicular drilling angle for straight holes and periodically withdraw the bit to clear accumulated dust, allowing the flutes to evacuate debris and reduce heat buildup.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling. Avoid prolonged continuous drilling; allow the bit to cool intermittently to preserve the carbide tip. For optimum performance, match drill diameter and speed settings to the material being drilled and consult the drill's manual for recommended hammer and rotation settings.
