Drill bit AWTools AW42856 — straight shank, 432 g

The AWTools AW42856 drill bit is a straight-shank masonry bit designed for drilling in concrete, brick, natural stone, granite and ceramic tiles. Constructed with a 40CR alloy steel body and a YG8C tungsten carbide head, this bit is suited for use with compatible hammer drills and rotary impact hammer drills. With a 2-cutter spiral geometry it balances chip evacuation and cutting stability for general-purpose workshop and construction drilling tasks. The product weight is 432 g and it is supplied as a durable replacement or spare bit for routine maintenance and on-site use.

Advantages

The combination of a 40CR alloy steel body and a YG8C tungsten carbide head provides wear resistance at the cutting tip while maintaining overall toughness in the shank. The 2-cutter spiral design promotes efficient removal of debris during drilling, which reduces heat build-up and limits vibration. A grooved SDS+ style shank secures the bit in compatible chucks to help prevent accidental loosening or falling out during operation. The bit is intended for use in both rotary and hammer drilling modes where appropriate.

Suitable for

• Drilling holes in concrete, masonry and brick for anchors and fasteners
• Creating openings in natural stone and granite for light fixtures or fixtures fixing
• Drilling through ceramic tiles when using controlled hammer or rotary drilling technique
• Workshop and construction site tasks requiring durable replacement drill bits

How to use

Select a drill and chuck compatible with a straight shank and SDS+ style grooves, and secure the bit according to the drill manufacturer's instructions. For masonry and concrete, use hammer or rotary impact mode as appropriate; for ceramic tiles, start on a low speed and avoid excessive hammering near the tile surface to reduce the risk of cracking. Apply steady axial pressure, withdraw periodically to clear debris if necessary, and allow the bit to cool during extended drilling to maintain cutting performance and tool life.

Usage recommendations

Use appropriate personal protective equipment including eye protection, dust mask and gloves. Match drill speed and hammer action to the material: higher impact for concrete and masonry, controlled rotary or reduced hammer action for tiles and delicate stone. Replace the bit when the cutting edge becomes worn or when drilling performance declines to avoid damage to workpieces and the drill.
