Drill bit AWTools AW43522 — metal/wood drilling bit, model AW43522

AWTools AW43522 is a multi-purpose drilling bit engineered for use with hand drills, hammer drills and rotary hammers. Constructed from 40Cr alloy steel with a YG8C carbide-tipped blade and a centering point with a 130° point angle, this drill bit is designed to deliver accurate starts and extended tip life. The double spiral flute and four cutting edges support efficient debris removal and smoother hole walls when working in hard materials.

Advantages

The YG8C carbide tip provides high wear resistance and improved edge retention compared to standard high-speed steel bits. The 130° centering point helps prevent walking at the start of drilling, allowing more precise hole placement. Double spiral flutes promote rapid dust and chip evacuation, reducing heat build-up and vibration during operation. A four-cutting-edge geometry creates cleaner holes and lowers the chance of jamming when encountering reinforcement. The grooved SDS+ shank secures the bit in compatible chucks to reduce slippage during heavy-duty work.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Drilling through rebar and dense masonry
• Creating openings in brick and other hard materials
• 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
• Flute design: double spiral for improved chip evacuation
• Cutting geometry: four cutting edges for smoother holes
• Shank type: grooved SDS+ shank to prevent falling out
• Intended materials: concrete, reinforced concrete, rebar, brick and other hard materials
• Compatible tools: hand drills, hammer drills and rotary hammers

How to use

Select a drill or rotary hammer compatible with SDS+ shanks and mount the AWTools AW43522 bit securely. Mark the drilling point and start at low speed to engage the centering point, then increase speed or engage hammer action as required for the material. Apply steady axial pressure without forcing the bit; allow the carbide tip and the tool’s impact action to work. Periodically withdraw the bit to clear accumulated dust and chips, and avoid prolonged continuous operation to limit heat build-up.

Usage recommendations

Use appropriate personal protective equipment including safety glasses and hearing protection. For reinforced concrete or rebar, use moderate hammer action and retract the bit regularly to clear debris. Match drill speed and hammer setting to the material hardness; use cooling pauses during extended drilling to prolong bit life.
