Drill bit AWTools AW43547, twist drill for metal and wood, universal size (AW43547)

AWTools AW43547 is a twist drill bit engineered for versatile drilling tasks in materials ranging from metal and wood to hard masonry. Constructed from 40CR alloy steel with a YG8C carbide-tipped cutting blade, the bit combines toughness and wear resistance for repeated use. Its centering point with a 130° point angle and four cutting edges enable stable entry and smooth hole walls, while the double spiral flute design promotes efficient chip evacuation and helps prevent overheating and excessive vibration. The grooved SDS+ style shank secures the bit in compatible hammer drills and rotary hammers for stable operation in demanding conditions.

Advantages

The combination of a 40CR alloy steel body and a YG8C carbide tip provides a balance of flexibility and hardness that extends tool life during drilling in abrasive or reinforced materials. The 130° centering point improves accuracy at the start of drilling and reduces walking on the workpiece. Double spiral flutes accelerate removal of debris and reduce heat build-up, while four cutting edges produce smooth holes and lower the chance of jamming when encountering rebar. The SDS+ style grooved shank ensures secure retention in hammer drills and rotary hammers for consistent performance.

Suitable for

• Drilling in concrete and reinforced concrete
• Drilling in rebar and other embedded metal elements
• Masonry work in brick and stone
• General-purpose drilling in metal and wood with rotary or non-hammer drills
• Workshop and on-site repair, renovation and installation tasks

How to use

Fit the AWTools AW43547 into a compatible chuck or SDS+ holder according to the drill/rotary hammer manufacturer's instructions and ensure the shank is locked securely. For masonry and reinforced materials use hammer drilling mode; for metal and wood use rotary mode without hammer action. Start drilling at low speed to establish the centering point, then increase speed and apply steady, moderate pressure. Allow the drill to clear debris periodically; for deep holes withdraw the bit occasionally to evacuate chips and prevent overheating. Use appropriate personal protective equipment, clamp or secure the workpiece, and follow safety guidelines for the power tool in use.

Usage recommendations

Choose drill speeds and feed pressure according to the work material: lower speeds and steady pressure for reinforced concrete and rebar, higher speeds for metal and wood. Regularly inspect the carbide tip for wear and replace the bit if chipping or significant bluntness appears. For best results in hard masonry, combine with appropriate dust extraction and avoid excessive side load to preserve cutting geometry.
