Drill bit AWTools AW43529 – metal/wood drilling accessory, standard twist bit

AWTools AW43529 is a standard twist drill bit designed for a range of drilling tasks in both metal and wood, and additionally engineered for demanding work in masonry and reinforced materials. Constructed from 40CR alloy steel with a YG8C carbide-tipped blade, the bit combines toughness with a hard cutting edge. A centering point with a 130° point angle and a double spiral flute geometry improve chip evacuation and reduce heat build-up, while four cutting edges produce smooth holes and lower the risk of jamming when encountering rebar. The grooved SDS+ shank secures the bit in hammer drills and rotary hammers for stable operation.

Advantages

The combination of 40CR alloy steel body and a YG8C carbide tip offers a balance of durability and cutting performance suitable for repeated use. The 130° centering point facilitates accurate starts and reduces walking on the surface. Double spiral flutes provide efficient chip removal to protect the cutting edge from overheating and to reduce vibration during drilling. Four cutting edges deliver clean hole finishes and improve performance when penetrating hard or reinforced materials. The grooved SDS+ shank ensures reliable retention in compatible hammer drills and rotary hammers, enabling safe and consistent drilling.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Working with brick and masonry
• Penetrating rebar and other reinforced materials
• General-purpose drilling in metal and wood for repair and fabrication
• Use with hammer drills and rotary hammers

Key specifications

• Material: 40CR alloy steel body with YG8C carbide-tipped cutting edge
• Point angle: 130° centering point
• Flute design: double spiral for improved chip evacuation
• Cutting edges: four cutting edges for smooth holes and reduced jamming risk
• Shank type: grooved SDS+ shank for secure retention in hammer tools
• Suitable materials: concrete, reinforced concrete, rebar, brick, wood, metal

How to use

Select a drill and tool holder compatible with the grooved SDS+ shank and secure the bit according to the tool manufacturer’s instructions. Mark the drilling point and start drilling at low speed to establish the center using the 130° point, then increase speed and apply steady pressure appropriate to the material. For masonry and reinforced concrete, use the hammer or rotary hammer function where applicable; for metal and wood, use rotary mode without hammer action. Maintain consistent feed and avoid excessive side loads to prolong bit life. Clear accumulated dust and chips periodically to preserve chip evacuation performance.

Usage recommendations

Use appropriate personal protective equipment, including eye and hearing protection, and follow safety guidance for hammer drills and rotary hammers. For best results in hard or reinforced materials, operate in short intervals to prevent overheating and allow the carbide tip to cool. Replace the bit if the cutting edge becomes rounded, chipped, or otherwise damaged to avoid inferior hole quality or increased risk of tool slippage.
