AWTools AW43505 is a replacement drill bit designed for general and heavy-duty drilling tasks. It combines a 40CR alloy steel body with a YG8C carbide-tipped blade and a centering point with a 130° point angle to provide stable, accurate starts. The bit features a double spiral flute and four cutting edges to ensure efficient material removal, reduced vibration and smooth hole walls. A grooved SDS+ shank secures the bit in compatible hammer drills and rotary hammers and prevents accidental release during use. The product is intended for drilling in concrete, reinforced concrete, rebar, brick and other hard workshop materials, and is suitable for both manual and machine operations in maintenance and repair work.
Advantages
The combination of a 40CR alloy steel body with a YG8C carbide tip increases wear resistance and extends service life in demanding conditions. The 130° centering point improves accurate positioning and reduces walking at the start of drilling. Double spiral flutes provide consistent removal of debris and contribute to lower operating temperatures, while four cutting edges produce cleaner holes and lower the risk of jamming when encountering rebar. The grooved SDS+ shank ensures a secure fit in compatible chucks, enabling reliable hammering and rotary action.
Suitable for
- Drilling in concrete and reinforced concrete
- Punching through rebar and structural reinforcement
- Drilling in brick and masonry
- Maintenance and repair tasks with hammer drills or rotary hammers
- Workshop and construction site applications requiring durable carbide-tipped bits

How to use
Fit the AWTools AW43505 drill bit into the compatible SDS+ chuck of a hammer drill or rotary hammer, ensuring the bit locks into place. Position the centering point on the marked drilling location and start at low speed to establish the hole, then increase to the appropriate drilling speed and hammer action for the material. Apply steady pressure without forcing the bit; allow the carbide tip and the hammer action to break the material. Periodically withdraw the bit to clear accumulated dust and debris from the flutes and to prevent overheating.
Usage recommendations
Use appropriate personal protective equipment such as safety glasses, gloves and hearing protection. Match drilling speed and hammer settings to material hardness, keep the bit straight during operation to avoid chipping the carbide tip, and replace the bit when wear impairs cutting performance. For reinforced concrete with dense rebar, use controlled short drilling intervals to avoid overheating and inspect the bit regularly for damage.
