Good for getting a nice neat job

I got this because I'm going to do some tile work in my bathroom. Using this will give a nice clean look instead of using nippers and a coated hacksaw blade. Remember the tool do the work otherwise you will just knock the diamonds off. I actually looked at this under a microscope and it doesn't have as many diamonds as it looks to have. Most of the sparkle is from the brazing

Pros
  • Not for thick materials but great for tile.
Cons
  • The diamond coating may wear off quickly after several uses

Great Bit Just As Described

This bit arrived just as described. Nicely packaged in a tube that has a loop on the lid making it easy to store the bit on a hook in my workshop along with my drills that are hung on the wall. The bit is a nice size for drilling vanity sink drain holes, which I always wanted to create a bathroom sink from a ceramic bowl, now I can with this handy bit.

Pros
  • 5/8-11 thread design ensures compatibility with most standard angle grinders and drilling machines
Cons
  • The bit may become magnetized after repeated use, making it difficult to clean

Worked exactly like you would hope.

I used this bit to drill a hole in ceramic tile, and it did a beautiful job. What more can you say for a drill bit, except that it does the job just the way you want it to?

Pros
  • ✿Sizes: Hole Saw Diameter :2-1/2" (65mm) ; Connection: 5/8"-11 ; Diamond height 5/8" (15mm), Total length: 2.4" (60mm). Remark: Max Cutting depth: 1-5/8" (40mm).
Cons
  • The bit may break if used with excessive force or at the wrong angle

Robust concrete bit

Good construction with heavy diamond coating which cut through concrete easily with water spray to keep it cool. Minimal wear was observed and expect many more holes capable to be drilled. Highest recommendations.

Pros
  • Exceptionally durable construction, ensuring long-lasting and efficient use
Cons
  • The bit may snag or catch on rough or uneven surfaces

GREAT DRILL BIT best in my review

The drill bit performs as expected and has a very sharp cutting action.It is also competitively priced among similar products in the market.

Pros
  • ✿Compatible Machines: Dry Diamond Core Drill Bit built with 5/8"-11 threading female arbor for most popular Angle Grinders, wet polisher; Do not use Core Drill Bits on Hammer Model.
Cons
  • The kit may not be able to create precise shapes or cuts

Threads on to what?

Unfortunately this comes with a threaded shank but no bit. my normal hole saws have a bit and a threaded collar. Will try threading this into the collar and update

Pros
  • Suitable for both professional and DIY applications, making it a valuable and affordable addition to any toolkit
Cons
  • The threading may not be compatible with all types of drill chucks

Convenient size for1/2 drill

The dry cutting core easily cut through my concrete basement floor for a drain location. No noticeable damage to the bit after one use.

Pros
  • Power & Hand Tools
Cons
  • It may create a lot of dust, which can cause respiratory problems if inhaled
