## Long description

The AWTools AW47288 diamond core drill bit is a specialized cutting tool featuring a 25mm diameter and a standard M14 thread connection. Built with a high-durability diamond grit coating, this core drill bit is engineered for precise, clean, and efficient drilling operations in a variety of hard building materials, ensuring smooth entry without cracking or chipping delicate surfaces.
Advantages
The high-durability diamond grit coating ensures an extended operational lifespan and consistent cutting performance even when working with extremely abrasive and dense materials. The M14 thread connection allows for quick and secure mounting directly onto compatible angle grinders without the need for additional adapters. Its specialized design minimizes material stress, delivering clean holes that reduce the need for subsequent finishing work or edge corrections.
Suitable for
Drilling clean holes in ceramic and porcelain tiles for plumbing fixtures
Creating precise openings in stone and hard tile surfaces during renovation projects
Professional construction and installation tasks requiring 25mm diameter holes
When it may not be suitable
This diamond core drill bit is not designed for drilling through structural metals, wood, or soft plastics, as the diamond grit requires hard, brittle materials to function correctly. It is also unsuitable for rotary hammers operating in hammer-drill mode, as impact force will damage the diamond coating.
Key specifications
Diameter: 25mmThread type: M14Coating: Diamond gritMaterial application: Tile, porcelain, ceramics, and stone
How to use
Ensure the diamond core drill bit is securely threaded onto the M14 spindle of your angle grinder before starting any work. Begin drilling at a slight angle to establish the initial groove, then gradually straighten the tool while maintaining a steady, moderate feed pressure. Utilize water cooling during operation where appropriate to reduce thermal stress, extend the lifespan of the diamond coating, and prevent dust accumulation.
What to consider before purchase
Verify that your power tool features a compatible M14 threaded spindle connection
Confirm the 25mm diameter matches the exact size requirements for your pipes or fixtures
Ensure appropriate cooling methods are available for extended drilling tasks
Usage recommendations: Always wear appropriate personal protective equipment including safety glasses and respiratory protection, and avoid applying excessive lateral pressure during the drilling process to prevent tool damage.
