Drill bit AWTools AW42863, model AW42863, weight 451 g

The AWTools AW42863 drill bit is a precision accessory weighing 451 g, designed for use with compatible hammer drills and rotary impact hammer drills. Constructed from 40CR alloy steel with a YG8C tungsten carbide head, this model is intended for drilling in masonry, concrete, granite, natural stone, brick and ceramic tiles. The bit features a grooved SDS+ shank to secure it in the chuck and a two-cutter spiral design for efficient material removal and reduced vibration during operation.

Advantages

The combination of 40CR alloy steel and a YG8C carbide head provides durability and wear resistance for heavy-duty drilling tasks. The 2-cutter spiral geometry promotes effective spoil evacuation, reducing overheating and maintaining cutting efficiency. The grooved SDS+ shank ensures reliable retention in compatible drill chucks, minimizing the chance of the bit slipping out under impact loads. Overall construction balances toughness and precision for consistent drilling results.

Suitable for

• Drilling holes in concrete and reinforced masonry
• Anchoring and fixing work in brick and natural stone
• Tile drilling for installations and repairs
• Workshop repairs and general construction tasks

How to use

Fit the AWTools AW42863 drill bit into a compatible SDS+ chuck, ensuring the shank engages the grooves and locks securely. Select the hammer or rotary mode appropriate for the material being drilled. Start drilling at low speed to establish a guide point, then apply steady pressure while allowing the drill's hammer action and the bit's spiral flutes to evacuate debris. Periodically withdraw the bit to clear dust and cool the tip when drilling deep holes. Use appropriate PPE including eye protection, gloves and hearing protection.

Usage recommendations

For prolonged tool life, avoid excessive lateral pressure and let the bit do the cutting. Use water or intermittent breaks only when drilling ceramic tiles to prevent thermal shock to the carbide tip. Match drill speed and hammer setting to the material: higher hammer action for concrete and masonry, reduced speed and moderate impact for tiles and natural stone.
