Drill bit AWTools AW42807 — metal/wood drilling accessory, straight shank

AWTools AW42807 — metal/wood drilling accessory, straight shank is a multi-purpose drill bit intended for workshop and DIY use. Made from 40CR alloy steel with two cutting edges and a carbide tip, this bit combines toughness with a hard-wearing cutting point. A double spiral flute evacuates chips efficiently to reduce heat buildup, while the grooved SDS+ shank secures the bit in compatible chucks for stable operation. The bit is designed for use in a range of materials when matched to appropriate drilling equipment and settings.

Advantages

The combination of 40CR alloy steel body and a carbide tip offers a balance of resilience and cutting durability suitable for repeated drilling tasks. Two cutting edges ensure consistent hole quality and reduced wandering at start-up. Double spiral flutes promote rapid chip removal and help control temperature during continuous use. The grooved SDS+ shank provides a reliable mounting interface that minimizes slippage in hammer drills and rotary hammers. Overall construction supports use across a variety of common building and workshop materials.

Suitable for

• Drilling into wood for carpentry and furniture work
• Drilling into metal for light fabrication and repair
• Drilling masonry, concrete, natural stone, brick and ceramic tiles with hammer drilling
• Use with hand drills, drill presses, hammer drills and rotary hammers that accept SDS+ shanks

Key specifications

• Material: 40CR alloy steel body with carbide tip
• Cutting geometry: two cutting edges
• Flute type: double spiral for chip evacuation
• Shank type: grooved SDS+ straight shank for secure mounting
• Suitable drilling materials: wood, metal, masonry, concrete, granite, natural stone, brick, ceramic tiles
• Compatible tools: hand drills, drill presses, hammer drills, rotary hammers

How to use

Select the appropriate drilling speed and feed rate according to the material: lower speeds for metal, higher speeds with light pressure for wood, and hammer mode for masonry and concrete when using a hammer drill or rotary hammer. Insert the grooved SDS+ shank fully into the compatible chuck or holder and ensure it locks in place before starting. Begin drilling with steady, even pressure; withdraw periodically when drilling deep holes to clear chips and allow cooling. Use water or cutting fluid where appropriate for metal or stone to extend tool life and improve cutting performance.

Usage recommendations

Wear appropriate personal protective equipment including safety glasses and hearing protection. Match drill mode and speed to the target material, and avoid excessive side loads to prevent breakage of the carbide tip. Inspect the bit before use for damage and replace if the tip is chipped or the flute is worn.
