Drill bit AWTools AW43503, diameter not specified, weight 43 g

AWTools AW43503 drill bit designed for rotary drilling applications in hard materials. Constructed with a 40CR alloy steel body and a YG8C carbide tipped blade, this single drill bit weighs 43 g and features a centering point with a 130° point angle. The double spiral flute and four cutting edges support smooth drilling and reliable debris evacuation. The grooved SDS+ shank secures the bit in compatible hammer drills and rotary hammers, reducing the risk of accidental ejection.

Advantages

The combination of a 40CR alloy steel body and a YG8C carbide tip provides improved wear resistance and edge retention compared with standard high-speed steel bits. The 130° centering point improves initial accuracy and reduces walking on the surface. Double spiral flutes accelerate dust and chip removal to limit heat build-up and vibration during operation. Four cutting edges produce cleaner, more precise holes and lower the chance of jamming when encountering reinforced material. The SDS+ grooved shank delivers secure retention in compatible chucks for stable, continuous drilling.

Suitable for

• Drilling in concrete and reinforced concrete
• Piercing brick and masonry
• Working with rebar and other reinforced structures
• Use with hammer drills and rotary hammers

How to use

Select a drill or rotary hammer compatible with SDS+ shanks and confirm the drill bit diameter matches the intended hole size. Fit the AWTools AW43503 into the chuck or SDS+ holder according to the tool manufacturer's instructions, ensuring it locks securely. Use hammer mode for concrete, reinforced concrete and masonry; use rotary-only mode for materials where hammering is not required. Start drilling at low speed to establish the centering point, then increase speed and apply steady pressure. Retract occasionally to clear debris and prevent overheating. Do not force the bit—allow the carbide tip to cut at its designed rate.

Usage recommendations

Wear appropriate personal protective equipment (safety glasses, hearing protection and dust mask) when drilling. For best results, match the bit diameter and length to the application, use correct hammer/rotary settings, and replace the bit if the carbide tip shows visible wear or chipping. Store in a dry place to avoid corrosion of the steel body.
