Drill bit AWTools AW43552 — metal/concrete drilling accessory, MPN AW43552

AWTools AW43552 drill bit is a heavy-duty replacement accessory designed for use with hammer drills and rotary hammers. Constructed from 40CR alloy steel with a YG8C carbide-tipped blade, the bit features a 130° centering point and four cutting edges to enable accurate, clean holes in concrete, reinforced concrete, rebar, brick and other hard materials. The double-spiral flute promotes efficient debris removal while reducing vibration and heat buildup, and the grooved SDS+ shank secures the bit during high-impact drilling.

Advantages

The combination of a 40CR alloy steel body and a YG8C carbide tip provides wear resistance and long service life under demanding conditions. The 130° centering point improves hole accuracy and faster bite on the material, while four cutting edges produce smooth hole walls and reduce the chance of jamming when encountering reinforcement. Double-spiral flutes evacuate dust and chips efficiently, helping to keep the bit cool and stable. The grooved SDS+ shank ensures reliable retention in compatible chucks for safe, continuous operation.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Drilling through rebar and masonry
• Installing anchors, plugs and fasteners during construction
• General repair, installation and assembly tasks requiring durable masonry bits

Key specifications

• Material: 40CR alloy steel body with YG8C carbide-tipped cutting head
• Tip geometry: centering point with 130° point angle
• Cutting edges: four cutting edges for smooth holes
• Flute design: double-spiral for efficient debris evacuation
• Shank type: grooved SDS+ for secure retention in compatible tools
• Application: suitable for concrete, reinforced concrete, rebar, brick and other hard materials
• Compatible tools: hammer drills and rotary hammers

How to use

Select a hammer drill or rotary hammer with an SDS+ chuck and insert the AWTools AW43552 drill bit until it locks into place. Mark the drilling position and start at low speed to establish the centering point, then apply steady pressure and increase drilling speed as appropriate for the material. Use the hammer function for concrete and reinforced concrete; withdraw periodically to clear dust from the hole and allow the bit to cool. When drilling through rebar or dense inclusions, reduce feed pressure slightly to avoid excessive stress on the tip and resume normal drilling once past the obstruction.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) and secure workpieces before drilling. For prolonged drilling sessions, intermittently retract the bit to remove debris and allow cooling. Match drill size to anchor or fastener requirements and avoid using the bit in rotary-only mode for heavy-duty concrete applications where hammer action is needed.
