Drill bit AWTools AW42865, model AW42865, weight 792 g

AWTools AW42865 drill bit model AW42865 is a durable single masonry drill bit weighing 792 g, designed for use with hammer drills and rotary impact hammer drills. Constructed from 40CR alloy steel with a YG8C tungsten carbide head, this drill bit is intended for drilling in masonry, concrete, granite, natural stone, brick and ceramic tiles. The tool features a grooved SDS+ shank for secure retention in compatible chucks and a 2-cutter spiral design to improve spoil removal and reduce overheating and vibration during use.

Advantages

The combination of a 40CR alloy steel body and a YG8C tungsten carbide head provides increased wear resistance and edge retention for demanding drilling tasks. The 2-cutter spiral geometry promotes efficient evacuation of dust and debris, which helps maintain drilling speed and reduces heat buildup. The grooved SDS+ shank prevents the drill bit from falling out under impact and ensures stable engagement with SDS+ compatible tools. The overall construction balances durability and compatibility for both professional and DIY applications.

Suitable for

• Drilling in masonry and concrete
• Working with granite and natural stone
• Holemaking in brick and ceramic tiles
• Use with hammer drills and rotary impact hammer drills featuring an SDS+ chuck
• Replacement or spare cutting accessory for compatible tool sets

How to use

Install the drill bit by inserting the grooved SDS+ shank into the chuck of an SDS+ compatible hammer drill or rotary impact hammer drill until it locks. Select an appropriate drilling mode and speed for the target material—use hammer mode for masonry and concrete and rotary mode with reduced impact for fragile tiles or natural stone when necessary. Start drilling with light pressure to establish the hole, then apply steady force without excessive downward pressure. Periodically withdraw the bit to clear debris and allow cooling; this helps maintain cutting efficiency and prolong the service life of the tungsten carbide head.

Usage recommendations

Use personal protective equipment such as safety glasses, gloves and hearing protection. For prolonged drilling in dense materials, pause occasionally to prevent overheating. Match the drill bit diameter to the anchor or fixture being installed and ensure the tool is compatible with SDS+ shanks before use.
