Drill bit AWTools AW42817, weight 158 g

AWTools AW42817 drill bit is a rotary drilling accessory engineered for masonry and stone applications. Constructed from 40Cr alloy steel with a carbide tip and two cutting edges, this bit is intended for use with compatible hammer drills and rotary hammers. The double spiral flute design aids efficient removal of drilled material and reduces heat buildup during continuous use. The SDS+ grooved shank secures the bit in the tool chuck to help prevent accidental release while working.

Advantages

The combination of 40Cr alloy steel body and a carbide tip provides a balance of toughness and wear resistance for drilling in hard substrates. Two cutting edges and a double spiral flute improve drilling speed and chip evacuation, which helps maintain cutting efficiency and reduces the risk of clogging. The SDS+ grooved shank ensures reliable retention in compatible hammer drills and rotary hammers, supporting safer and more consistent operation. The documented weight (158 g) contributes to predictable handling and balance when fitted to handheld tools.

Suitable for

• Drilling in masonry and concrete

How to use

Install the AWTools AW42817 drill bit into an SDS+ compatible chuck until it locks into place. Select a suitable drilling speed and hammer function according to the substrate: use hammer action for concrete and masonry, and reduced impact or rotary-only mode for delicate tiles or ceramics if applicable. Apply steady, even pressure and allow the bit to progress without forcing; periodically withdraw the bit to clear accumulated dust and debris for improved chip evacuation and cooling. For long or deep holes, pause occasionally to let the bit cool and to remove material buildup from the flutes.

Usage recommendations

Wear appropriate personal protective equipment including safety glasses, hearing protection and dust mask. Use water sparingly or only when recommended for the specific material and bit type. Match drill speed and hammer setting to the material being drilled to extend bit life. Inspect the bit for wear or damage before use and replace if the carbide tip or cutting edges are chipped or excessively worn.
