Drill bit AWTools AW42803 — AW42803, weight 40 g

The AWTools AW42803 drill bit is a compact, single-bit solution for demanding drilling tasks. Constructed from 40CR alloy steel with a carbide tip and two cutting edges, this bit is engineered for controlled penetration and long-lasting performance. Its double spiral flute design improves debris evacuation and reduces heat buildup, while the grooved SDS+ shank secures the bit in hammer drills and rotary hammers to prevent accidental release. Weighing 40 g, the AW42803 is suitable for a range of jobs where a durable, standard-size masonry drill bit is required.

Advantages

The combination of 40CR alloy steel body and a carbide tip provides enhanced wear resistance and maintains cutting sharpness when drilling hard materials. The double spiral flute ensures efficient removal of dust and chips, lowering friction and the risk of overheating. The grooved SDS+ shank offers reliable retention in compatible hammer drills and rotary hammers, improving safety and work continuity. Its compact weight and standard geometry make it easy to handle and replace in most drill chucks and holders designed for SDS+ bits.

Suitable for

• Drilling in masonry and concrete
• Working with granite, natural stone and brick
• Installing anchors, fasteners and through-holes in ceramic tiles (with care)
• Use with hammer drills and rotary hammers for renovation and construction tasks

How to use

Fit the AWTools AW42803 drill bit into a compatible SDS+ holder or chuck, ensuring it locks into place. Select hammer or rotary mode on the drill if working with masonry, concrete or stone; use rotary-only mode for more delicate ceramic tile operations and apply light pressure to avoid cracking. Start drilling at low speed to establish the hole, then increase speed and maintain steady, moderate pressure. Periodically withdraw the bit to clear debris and allow cooling, especially when drilling hard materials.

Usage recommendations

Use appropriate personal protective equipment, including eye and ear protection and a dust mask. For prolonged drilling or thicker materials, pause occasionally to prevent overheating and extend tool life. When drilling tiles, protect the surface with tape and use gentle pressure to reduce the chance of chipping.
