Drill bit AWTools AW42855 — model AW42855, weight 341 g

AWTools AW42855 drill bit, model AW42855, weighing 341 g, is a single-purpose cutting accessory designed for drilling in masonry and stone materials. Constructed with a 40CR alloy steel body and a YG8C tungsten carbide head, the bit is intended as a replacement or spare for compatible hammer drills and rotary impact hammer drills. Its grooved SDS+ shank ensures secure retention in the tool chuck while the 2-cutter spiral design facilitates efficient spoil removal.

Advantages

The combination of a 40CR alloy steel shaft and a YG8C tungsten carbide head provides wear resistance and cutting durability for demanding materials such as concrete and natural stone. The 2-cutter spiral geometry improves chip evacuation, reduces heat build-up and lowers vibration during operation. The grooved SDS+ shank prevents the bit from falling out, offering reliable connection with compatible hammer drills and rotary impact hammer drills.

Suitable for

• Drilling holes in masonry and concrete structures
• Working with granite and natural stone
• Installing anchors or fasteners in brickwork
• Cutting holes through ceramic tiles when using appropriate technique

Key specifications

• Material body: 40CR alloy steel
• Cutting head: YG8C tungsten carbide
• Shank type: grooved SDS+
• Spiral: 2-cutter spiral design for chip evacuation
• Intended tool types: hammer drills and rotary impact hammer drills
• Weight: 341 g

How to use

Insert the grooved SDS+ shank into a compatible hammer drill or rotary impact hammer drill and ensure it locks into place before operation. Select an appropriate drill speed and hammering mode based on the material being drilled. Apply steady axial pressure without forcing the bit; allow the tool and tungsten carbide head to cut at their designed rate. Withdraw the bit periodically to clear accumulated dust and debris if drilling deep holes, and avoid continuous high-speed operation that could increase heat and accelerate wear.

Usage recommendations

Use the AWTools AW42855 drill bit with steady pressure, in a correctly set hammer or rotary impact mode for masonry materials. For best results, wear appropriate personal protective equipment, use dust extraction or wet methods where applicable, and replace the bit once cutting performance noticeably declines to maintain hole quality and safety.
