Diamond core drill bits,3-1/2 in,dry

Made of premium carbon steel with diamond-grit teeth, this core drill bit maintains sharpness while cutting and grinding hard materials, delivering excellent wear resistance and long-lasting durability.

Our diamond dry coring bit includes three adapters for easy compatibility with SDS Plus, SDS Max, and 1/2 in hex drill bits. No need for additional purchases—this set handles all your drilling needs.

Crafted with high-precision welding for excellent wear resistance and high-temperature stability, this concrete core drill bit keeps diamond teeth strong and secure under tough drilling conditions, minimizing tooth loss or detachment for long-lasting durability.

This diamond core drill bit is easy to use. First, insert the pilot drill into the adapter, ensuring the drill’s angle matches the adapter bolt hole. Tighten the screws securely. The pilot drill must be centered, with a deviation no greater than 1 mm for accurate drilling.

The core bit ensures clean, precise holes in tough materials like red bricks, concrete, and foam blocks. Suitable for all your drilling needs in construction and renovation projects.
