## Long description

Diamond Crown AW 1 1/4" 132/430mm drill bit from AWTools is a diamond-tipped coring bit engineered for precision drilling in hard materials. Designed with a 1 1/4" connection, a cutting diameter of 132 mm and an overall length of 430 mm, this coring bit is suitable for creating clean circular holes in concrete, stone and masonry when used with compatible rotary or core drilling rigs. The diamond crown tip provides cutting durability and steady performance during wet or dry coring depending on the application and equipment used.
Advantages
The AWTools Diamond Crown coring bit combines a reinforced steel body with a diamond-segment cutting crown to deliver consistent hole quality and extended abrasive life. Its standardized 1 1/4" thread connection ensures compatibility with a wide range of core drilling machines and handheld rigs. The 132 mm cutting diameter and 430 mm overall length allow for deep, accurate coring while maintaining stability during operation. The diamond cutting surface reduces chipping on brittle materials and supports efficient material removal.
Suitable for
 Creating circular openings in reinforced and plain concrete
 Drilling through natural stone and engineered stone
 Forming holes in brick, blockwork and masonry
 Installing pipework, conduits and anchor points

How to use
Mount the drill bit onto a compatible core drill or rotary rig with a matching 1 1/4" connection. Secure the workpiece or position the drill rig on a stable surface before starting. Begin drilling at low speed to establish the pilot contact, then increase speed and apply steady, even pressure. Use adequate cooling or flushing (water) where recommended to extend diamond life and reduce dust; follow the core drill manufacturer's instructions for speed, feed and cooling. Withdraw the bit periodically to remove debris and prevent clogging of diamond segments.
Usage recommendations
For best results and longer tool life, use wet drilling when working in reinforced concrete or highly abrasive aggregates. Inspect the diamond crown regularly for wear and replace the bit when cutting efficiency noticeably decreases. Match drill speed and feed to material hardness and follow safety procedures including eye, hearing and respiratory protection.
