Drill bit AWTools AW42824 — for general drilling applications, compatible with standard drill chucks

AWTools AW42824 is a drill bit engineered for general drilling applications, compatible with standard drill chucks and intended for use in masonry and common construction materials. Constructed from 40CR alloy steel with a carbide tip and two cutting edges, the AW42824 combines hardness and edge retention for consistent hole quality. The double spiral flute design helps evacuate debris and reduce heat buildup, while the grooved SDS+ shank secures the bit in hammer drills and rotary hammers for reliable operation in impact modes.

Advantages

The combination of 40CR alloy steel and a carbide tip provides improved wear resistance and extended service life compared with plain steel bits. Two cutting edges produce efficient material removal and accurate hole geometry. Double spiral flutes promote fast debris extraction and cooling during drilling, decreasing the risk of clogging or overheating. The grooved SDS+ shank prevents accidental ejection from the chuck and ensures stable engagement with compatible hammer drill and rotary hammer chucks.

Suitable for

• Drilling in masonry and concrete
• Working with granite and natural stone
• Creating holes in brick
• Cutting through ceramic tiles (with appropriate technique)
• Use in hammer drills and rotary hammers with compatible chucks

Key specifications

• Material: 40CR alloy steel body with carbide tip
• Cutting geometry: two cutting edges
• Flute type: double spiral flute for debris removal
• Shank style: grooved SDS+ shank for secure engagement
• Intended materials: masonry, concrete, granite, natural stone, brick, ceramic tiles
• Compatibility: standard drill chucks and hammer drill/rotary hammer impact modes (with SDS+ compatible holders)

How to use

Select a drill and chuck or holder compatible with the grooved SDS+ shank and mount the AWTools AW42824 bit securely. When drilling, start at low speed to establish a guide point, then apply steady pressure and use the hammer function for hard materials such as concrete or stone. Withdraw the bit periodically to clear debris and allow cooling; the double spiral flute aids evacuation but manual clearing helps maintain cutting efficiency. For ceramic tiles, begin with light contact and avoid excessive impact near edges to reduce chipping.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves, dust mask) and secure the workpiece before drilling. Match drill speed and hammer settings to the material: lower speeds and light impact for tiles, higher impact for concrete and masonry. Inspect the carbide tip before use and replace the bit when wear or chipping affects hole quality.
