Drill bit AWTools AW42847, ø/size not specified, weight 369 g

AWTools AW42847 drill bit is a construction-grade masonry drill designed for use with handheld and stationary drills. The bit combines a 40CR alloy steel body with a YG8C tungsten carbide head, and features a 2-cutter spiral geometry and an SDS+ grooved shank. The manufacturer supplies the model AW42847 as a ready-to-use solution for drilling in masonry, concrete, granite, natural stone, brick and ceramic tiles; weight is 369 g. Diameter and exact size are not specified, so users should verify chuck compatibility and application requirements before selecting this bit.

Advantages

The combination of a 40CR alloy steel shaft and a YG8C tungsten carbide head provides a balance of toughness and cutting durability, while the 2-cutter spiral design improves chip evacuation and reduces heat build-up and vibration during drilling. The grooved SDS+ shank secures the bit in compatible hammer and rotary impact hammer drills, preventing slippage and making bit changes faster. The overall construction is aimed at repeated use in hard materials typical of masonry work.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Penetrating natural stone and granite for fixture installation
• Creating anchor or through-holes in brick and block walls
• Drilling ceramic tiles with care to avoid surface chipping
• Use in hammer drills and rotary impact hammer drills with SDS+ chuck

How to use

Install the AWTools AW42847 drill bit into an SDS+ compatible chuck and ensure it locks into place. When drilling masonry or concrete, use hammer mode on the drill and apply steady axial pressure without forcing the bit. For ceramic tiles, start at low speed and use a light touch or a guide to minimize surface chipping; switch to hammer mode only after penetrating the tile if required. Periodically withdraw the bit to clear debris and allow cooling, and do not exceed the recommended operating conditions of your drill.

Usage recommendations

Verify that your drill accepts SDS+ shanks and confirm the required hole diameter before use, as the AW42847 model does not specify size. Wear appropriate personal protective equipment (eye protection, gloves, dust mask) and use water cooling or intermittent drilling in hard stone to extend carbide tip life. Replace the bit if excessive wear, chipping of the carbide head, or unusual vibration occurs.
