Drill bit AWTools AW42894 — metal/wood/general-purpose, MPN AW42894

The AWTools AW42894 drill bit is a general-purpose accessory designed for use with hammer drills and rotary impact hammer drills. Constructed from 40CR alloy steel with a YG8C tungsten carbide head, the bit combines toughness and a wear-resistant cutting tip to handle repeated drilling in masonry, concrete, granite, natural stone, brick and ceramic tiles. The 2-cutter spiral geometry supports efficient chip removal and reduced vibration, while the grooved SDS+ shank provides secure retention in compatible chucks.

Advantages

The combination of 40CR alloy steel and a YG8C carbide head delivers reliable durability and cutting performance when drilling hard materials. The 2-cutter spiral design improves removal of spoil and helps prevent overheating during extended use, reducing bit wear and minimizing vibration transmitted to the tool. The grooved SDS+ shank ensures a stable connection with SDS+ compatible drill holders, preventing accidental release and allowing quick bit changes.

Suitable for

• Drilling holes in concrete and masonry for anchors and fasteners
• Making openings in brick and natural stone for installation work
• Working on ceramic tiles and granite for renovation and repair
• Routine construction, maintenance and DIY drilling tasks

Key specifications

• Material: 40CR alloy steel body with YG8C tungsten carbide cutting head
• Cutter design: 2-cutter spiral for efficient chip evacuation
• Shank type: grooved SDS+ shank for secure retention
• Intended materials: masonry, concrete, granite, natural stone, brick, ceramic tiles
• Tool compatibility: hammer drills and rotary impact hammer drills

How to use

Select an appropriate diameter and mark the drilling point. Fit the AWTools AW42894 bit into an SDS+ compatible chuck and ensure it is fully seated and locked. When drilling hard materials such as concrete or tile, start at low speed to establish the hole, then increase speed and apply steady pressure while allowing the bit to clear debris. For deep holes, withdraw the bit periodically to remove accumulated spoil and avoid overheating. Use appropriate personal protective equipment including eye protection and a dust mask.

Usage recommendations

Use the bit with a hammer function enabled only when required for masonry or concrete; disable hammer action for delicate tile work to prevent cracking. Match drilling speed and pressure to the material and check the bit for wear before extended use to maintain consistent performance.
