The bit went through a brick layer and then the center (braced) section of a CMU (cinder block) pretty easily in about 15 minutes. Looks like it should be good for at least one more hole but for the price of it,I'm happy with the purchase.

Use this to bore holes in all sorts of walls. We wear them down to the nub before replacing it. We can usually bore 3 to 4 holes, sometimes more, before replacing it.

A waste of my time and money. Pilot bit shorter than the core bit, no way to keep the core bit from walking to get the hole started. Vevor hasn't let me down before but this was ridiculous.

Took too long to receive 🙌. The center bit is too short. I ordered a new one when I got home the one I ordered was there. Now I have to figure out how to cancel new order.

Description
4-1/2 Inch Dry Diamond Core Drill Bit
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.
