Drill bit AWTools AW43516

AWTools AW43516 is a drill bit engineered for drilling in hard materials such as concrete, reinforced concrete, rebar, brick and other masonry. Constructed from 40CR alloy steel with a YG8C carbide-tipped blade, the AW43516 combines toughness in the body with a wear-resistant cutting tip. The centering point uses a 130° point angle to improve penetration and accuracy, while the SDS+ grooved shank ensures secure retention in compatible hammer drills and rotary hammers.

Advantages

The double-spiral flute design provides efficient removal of drilled material, helping to protect the bit and tool from overheating and reducing vibration during operation. Four cutting edges provide smooth, consistent holes and lower the risk of jamming when encountering rebar. The carbide tip increases cutting life and performance in abrasive and dense substrates, while the hardened 40CR body maintains structural strength under impact loads typical for hammer drilling.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Working with brick and masonry
• Piercing rebar and other embedded metal during demolition or installation
• Use with SDS+ compatible hammer drills and rotary hammers
• General workshop, construction and DIY drilling tasks in hard materials

Key specifications

• Material: 40CR alloy steel body with YG8C carbide-tipped cutting blade
• Point angle: 130° centering point
• Flute design: Double spiral for efficient chip removal and reduced heat
• Cutting geometry: Four cutting edges for smooth holes and improved cutting stability
• Shank type: Grooved SDS+ shank for secure retention in compatible drills
• Application: Designed for concrete, reinforced concrete, rebar, brick and similar hard materials

How to use

Install the AWTools AW43516 into an SDS+ compatible hammer drill or rotary hammer according to the tool manufacturer’s instructions. For best results in masonry and reinforced concrete, start drilling at low speed to establish the centering point, then apply steady pressure and allow the hammer action to do most of the work. Periodically withdraw the bit to clear accumulated dust and debris from the hole. When hitting rebar, reduce feed force and maintain tool alignment to avoid excessive bending or chipping of the carbide tip.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust control. Select drill speeds and hammer settings that match the material and bit diameter. Replace the bit when the carbide tip shows significant wear, chipping, or loss of cutting efficiency to maintain drilling quality and safety.
