Drill bit AWTools AW42829 — general-purpose metal/wood drilling, straight shank

AWTools AW42829 — general-purpose drill bit with a straight shank designed for drilling in a range of building and workshop materials. Constructed from 40CR alloy steel with a carbide tip and two cutting edges, this single bit is intended for use with compatible handheld drills, hammer drills and rotary hammers. A double spiral flute provides efficient chip removal and helps reduce overheating during continuous work.

Advantages

The combination of 40CR alloy steel body and a carbide tip offers wear resistance and consistent cutting performance on harder materials. Two cutting edges deliver accurate hole formation while the double spiral flute accelerates evacuation of debris. A grooved SDS+ shank secures the bit in the chuck or tool holder to reduce the risk of slipping or falling out during drilling in demanding conditions.

Suitable for

• Drilling in masonry and concrete
• Drilling in granite and natural stone
• Drilling in brick and ceramic tiles
• General metal and wood drilling tasks
• Use with hammer drills and rotary hammers

Key specifications

• Material: 40CR alloy steel body with carbide tip
• Cutting edges: two cutting edges
• Flute design: double spiral flute for chip evacuation
• Shank type: grooved SDS+ shank
• Intended use: masonry, concrete, natural stone, granite, brick, ceramic tiles, metal and wood
• Delivery: single straight-shank bit

How to use

Select a compatible drill or rotary hammer with an SDS+ chuck or appropriate adapter. Secure the AWTools AW42829 bit in the tool holder so the grooved SDS+ shank engages correctly. For masonry, concrete or stone, use the hammer function as required; for metal and wood, use rotary drilling without percussion. Start at low speed to position the bit, then increase speed to the recommended range for the material being drilled. Apply steady pressure, allow the bit to cut, and avoid excessive force that may cause overheating or premature wear.

Usage recommendations

For longer bit life and consistent performance, clear accumulated debris regularly, avoid continuous high-speed operation without pauses, and inspect the carbide tip for wear. Use appropriate personal protective equipment and follow the drill manufacturer's guidance for speed and hammer settings for each material.
