Drill bit AWTools AW42848 — solid metal bit, weight 457 g

The AWTools AW42848 solid metal drill bit is designed for standard drilling tasks in masonry and stone. Constructed from 40CR alloy steel with a YG8C tungsten carbide head, this bit weighs 457 g and features a 2-cutter spiral geometry for efficient spoil removal. The grooved SDS+ shank secures the bit in compatible hammer drills and rotary impact hammer drills, providing a reliable solution for routine hole-making in workshop and construction environments.

Advantages

The combination of a durable 40CR alloy steel body and a YG8C carbide tip gives a balance of toughness and cutting performance. The 2-cutter spiral design clears debris effectively, reduces vibration and helps prevent overheating during sustained use. The grooved SDS+ shank improves retention in the drill chuck, minimising bit slippage under hammering action. The bit is suitable for a range of hard materials including masonry, concrete, granite, natural stone, brick and ceramic tiles, offering versatility across common building tasks.

Suitable for

• Drilling holes in concrete and reinforced masonry
• Fixing anchors and dowels in brick and stone
• Installing plumbing and electrical conduits through walls
• Tile and ceramic drilling for fixtures and fittings

How to use

Install the AWTools AW42848 bit into a compatible hammer drill or rotary impact hammer with an SDS+ chuck, ensuring the groove on the shank engages properly. Select an appropriate drilling speed and apply steady pressure; allow the hammer action to do the cutting in hard materials. Periodically withdraw the bit to clear accumulated debris from the hole and to check the bit and work surface. For deeper holes, withdraw the bit more frequently to avoid clogging and overheating.

Usage recommendations

Use personal protective equipment including safety glasses, hearing protection and appropriate dust control when drilling masonry or ceramic materials. Match drill speed and feed pressure to the material: lower speeds and steady pressure for very hard stone or tile, higher impact rate for concrete and brick. Inspect the carbide tip before use and replace the bit if the tip shows excessive wear or chipping to maintain efficient and safe drilling.
