Drill bit AWTools AW42838 — model AW42838, weight 363 g

AWTools AW42838 is a compact drill bit designed for handheld use with compatible electric drills, hammer drills and rotary hammers. The single-piece bit weighs 363 g and combines a 40Cr alloy steel body with a carbide tip and two cutting edges, providing reliable performance for drilling into masonry, concrete, granite, natural stone, brick and ceramic tiles. A double spiral flute ensures efficient removal of drilling debris and helps prevent overheating, while the grooved SDS+ shank secures the bit in the chuck to reduce the risk of accidental release during work.

Advantages

The AWTools AW42838 features a carbide-tipped, two-edge cutting geometry for precise entry and sustained cutting performance in hard materials. The 40Cr alloy construction provides strength and wear resistance while the double spiral flute accelerates dust and chip evacuation to maintain drilling efficiency and reduce heat build-up. The grooved SDS+ shank offers quick, secure fitting and improved retention in compatible hammer drills and rotary hammers.

Suitable for

• Drilling anchor and fixing holes in concrete and masonry
• Creating holes for pipe and cable entries in brick and natural stone
• Drilling through ceramic tiles with careful technique
• Work with hammer drills and rotary hammers on construction sites and renovation projects

How to use

Fit the AWTools AW42838 into a compatible SDS+ chuck according to the drill manufacturer's instructions until it locks securely. Select appropriate drill speed and hammer function depending on the material: use hammer mode for concrete and masonry, and rotary-only or low-hammer settings for ceramic tiles to avoid cracking. Start drilling with a steady, even pressure and allow the bit's carbide tip to engage the material. Periodically withdraw the bit to clear accumulated dust and chips and to allow cooling.

Usage recommendations

Use personal protective equipment such as safety glasses, gloves and a dust mask when drilling. For prolonged drilling in hard materials, pause periodically to prevent overheating and consider using water cooling only where compatible with the tool and work environment. Ensure the drill and bit are compatible with SDS+ shanks and match the bit diameter to the intended fixings or anchors.
