Drill bit AWTools AW42872, model AW42872, weight 707 g

AWTools AW42872 drill bit model AW42872 is a masonry and concrete drilling bit with a weight of 707 g. Constructed from 40CR alloy steel with a YG8C tungsten carbide head, this bit is intended as a replacement or spare for compatible hammer drills and rotary impact hammer drills. Its 2-cutter spiral design and SDS+ grooved shank provide stable engagement with the tool and efficient evacuation of material during drilling.

Advantages

The 40CR alloy steel body offers strength and toughness while the YG8C tungsten carbide head delivers wear resistance and long life when working with hard materials. The 2-cutter spiral geometry removes spoil effectively, lowering friction and the risk of overheating. The grooved SDS+ shank ensures the bit locks securely in compatible chucks and prevents accidental ejection during hammering action.

Suitable for

• Drilling in masonry and concrete
• Drilling granite and natural stone
• Drilling brick and ceramic tiles
• Use with hammer drills and rotary impact hammer drills

How to use

Select a drill or rotary hammer with an SDS+ chuck that matches the shank of the AWTools AW42872. Secure the bit in the chuck so the groove locks into place. For masonry and concrete, use the hammer or impact mode as required by the material. Start drilling at low speed to establish the hole, then increase speed and apply steady, controlled pressure. Withdraw the bit periodically to clear debris and allow cooling, especially when drilling deep holes or hard stone.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and dust mask when drilling. Verify tool compatibility (SDS+ chuck and hammer function) before use. For longer bit life, avoid excessive lateral force and allow the bit to cool by pausing on prolonged drilling tasks.
