Drill bit AWTools AW42866 – AWTools AW42866

Drill bit AWTools AW42866 is a replacement cutting tool intended for drilling applications in construction and workshop settings. Manufactured with a 40CR alloy steel body and a YG8C tungsten carbide head, the bit combines toughness in the shank with a wear-resistant cutting tip. The 2-cutter spiral design and grooved SDS+ shank provide reliable spoil evacuation and secure retention in compatible hammer and rotary impact drills.

Advantages

The combination of a 40CR alloy steel shank and a YG8C tungsten carbide head delivers balance between durability and cutting performance. The 2-cutter spiral geometry removes material efficiently, reduces vibration and helps prevent overheating during prolonged use. The grooved SDS+ shank ensures the drill bit remains locked in place under hammering action, improving safety and accuracy when working with hard materials.

Suitable for

• Drilling holes in masonry and concrete
• Working with granite and natural stone
• Perforating brick and ceramic tiles
• Use with hammer drills and rotary impact hammer drills

Key specifications

• Body material: 40CR alloy steel
• Tip material: YG8C tungsten carbide
• Cutting geometry: 2-cutter spiral design for efficient chip removal
• Shank type: Grooved SDS+ for secure retention
• Application materials: masonry, concrete, granite, natural stone, brick, ceramic tiles
• Compatible tools: hammer drills and rotary impact hammer drills

How to use

Select a drill with an SDS+ chuck or an adapter that accepts SDS+ shanks and secure the AWTools AW42866 bit. Mark the drilling point, start at low speed to establish the hole, then increase hammering action and speed according to the material. Apply steady, moderate pressure; avoid forcing the bit to reduce risk of breakage and overheating. Withdraw the bit periodically to clear accumulated debris for deeper holes.

Usage recommendations

Use appropriate personal protective equipment, including eye and ear protection and dust mask when drilling masonry or concrete. Match drilling speed and hammer action to the material: lower speeds for tile and natural stone, higher hammer settings for concrete and brick. Replace the bit once cutting performance deteriorates to maintain clean holes and safe operation.
