Drill bit AWTools AW42843 — standard twist drill bit for metal and wood

AWTools AW42843 — standard twist drill bit for metal and wood is a single-piece rotary cutting tool engineered for general-purpose drilling. The bit combines a two-cutting-edge geometry with a carbide tip to improve penetration and wear resistance. Double spiral flutes evacuate chips efficiently and help control heat buildup during continuous use. The grooved SDS+ shank secures the bit in compatible chucks to reduce slippage and accidental release.

Advantages

The 40CR alloy steel body with a carbide-tipped cutting point delivers a balance of toughness and hardness appropriate for mixed-material tasks. Two cutting edges provide stable centring and consistent hole quality, while the double spiral flute design improves chip evacuation and cooling. The SDS+ grooved shank ensures reliable retention in hammer drill and rotary hammer chucks, reducing runout and improving user safety.

Suitable for

• Drilling through masonry, concrete and reinforced concrete for anchor and through-hole work
• Creating holes in brick, natural stone and granite for installations and fixtures
• Drilling ceramic tiles where controlled entry and chip removal are required
• Light metal and wood drilling tasks when using appropriate speed and clamping

Key specifications

• Material: 40CR alloy steel body with carbide tip
• Cutting geometry: two cutting edges
• Flute type: double spiral flute for chip evacuation
• Shank type: grooved SDS+ for secure retention in compatible chucks
• Suitable tools: hammer drills and rotary hammers; also usable in hand drills with appropriate adapter

How to use

Select an appropriate drill size and clamp the workpiece securely. Fit the AWTools AW42843 into a compatible SDS+ chuck or use an adapter for other chucks. Use a hammer function when drilling into masonry, concrete, stone or brick; use rotary mode for metal, wood or tiles without impact. Start at low speed to establish the pilot position, then increase speed and apply steady, moderate pressure. Periodically withdraw the bit to clear chips and allow cooling for longer holes.

Usage recommendations

For best results, match drilling mode to the material: use impact mode for concrete and masonry, and rotary-only mode for metal, wood and ceramic tiles. Keep the bit aligned with the hole axis, avoid excessive side force, and replace the bit when the carbide tip shows visible wear or chipping. When drilling hard stone or dense concrete, use intermittent drilling and allow the bit to cool to extend service life.
