Drill bit AWTools AW43543 — replacement drill bit for general-purpose drilling

AWTools AW43543 — replacement drill bit for general-purpose drilling is a carbide-tipped accessory designed for routine and maintenance drilling tasks. Constructed from 40CR alloy steel with a YG8C carbide tip, this drill bit features a centering point with a 130° point angle and a double spiral flute for efficient removal of cut material. The SDS+ grooved shank secures the bit in hammer drills and rotary hammers, while four cutting edges provide smooth hole finishes and reduce the risk of jamming when encountering reinforcement.

Advantages

The combination of a 40CR steel body and a YG8C carbide tip delivers a balance of toughness and wear resistance suitable for hard materials. The 130° centering point improves accuracy at drill start and reduces walking. Double spiral flutes promote consistent dust and debris evacuation, lowering operating temperatures and vibrations. Four cutting edges ensure clean, smooth holes and improved performance when drilling into concrete, reinforced concrete, rebar and brick. The SDS+ grooved shank offers quick, secure mounting in compatible hammer drills and rotary hammers.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Drilling through rebar and other metal reinforcements
• Perforating brick and masonry
• General-purpose maintenance and repair drilling with hammer drills or rotary hammers

How to use

Install the AWTools AW43543 drill bit into an SDS+ compatible holder, ensuring the groove locks into place. For best results in concrete and masonry, use a hammer drilling mode with moderate, steady pressure and allow the tool to do the work. Start drilling at low speed to establish the centering point, then increase speed as the bit progresses. Periodically withdraw the bit to clear accumulated dust and debris and to reduce heat buildup. When encountering rebar, maintain steady feed and avoid excessive force to prevent bit damage.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask. For extended drilling sessions, allow the bit to cool periodically and use lubricant or water only if recommended by the tool manufacturer. Store the bit in a dry place to avoid corrosion and inspect before use for signs of wear or damage; replace when the carbide tip is worn or chipped.
