Drill bit AWTools AW43541 — twist drill bit, model AW43541

AWTools AW43541 is a twist drill bit designed for drilling in hard building materials. Constructed with a 40Cr alloy steel body and a YG8C carbide-tipped blade, this model features a centering point with a 130° point angle and a double-spiral flute geometry. The drill bit is intended for use with standard hammer drills and rotary hammers and is suitable for making holes in concrete, reinforced concrete, rebar, brick and similar hard substrates. The grooved SDS+ shank secures the bit in the tool and helps prevent accidental release during operation.

Advantages

The carbide-tipped cutting head provides wear resistance and maintains sharpness when working with abrasive materials. The double-spiral flutes improve dust and debris evacuation, reducing heat buildup and vibration during drilling. Four cutting edges produce smooth, accurately sized holes and reduce the tendency to jam when encountering reinforcing bars. The SDS+ grooved shank ensures a secure mechanical connection to compatible hammer drills and rotary hammers.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Drilling through rebar and dense masonry
• Installation of anchors, dowels and fixing points
• Use with hammer drills and rotary hammers for construction and renovation tasks

Key specifications

• Tool compatibility: hammer drills and rotary hammers

How to use

Mount the AWTools AW43541 into a compatible hammer drill or rotary hammer with an SDS+ chuck, ensuring the grooved shank locks into position. Select an appropriate drill speed and mode for the material and tool: use hammer mode for masonry and reinforced concrete, and rotary-only mode for lighter masonry if required. Apply steady, moderate pressure and allow the drill bit to do the work; avoid excessive force that could overheat the bit. Periodically withdraw the bit to clear accumulated dust and debris from the hole and flutes.

Usage recommendations

For longer service life, use cooling intervals during prolonged drilling and clear debris frequently. When drilling through rebar, slow the feed slightly and avoid abrupt twists to reduce stress on the carbide tip. Always use proper personal protective equipment, including eye and hearing protection, and follow the tool manufacturer's instructions.
