BEAMNOVA Set of 16 Diamond Drill Bits with Jig Ceramic Tile Hole Drilling Set Kit 6mm-50mm 1/4~2 Inch Hole Saw Set for Glass Stone Granite Marble

the hole saws all put in one plastic bag. did no do the diamond cutting medium any favors the inside of the bag was covered in diamond dust so mounted the holesaws in a board to keep them from wearing the diamond medium off. put it all back in the original box for storage.this indicates that the mfg has little to no quality control. the sizes of the holes made is barely within tolerance. no sizes on the holesaws themselves.aside from this the hole made in the glass bottle was adequate.

I buy crap from Amazon almost daily it feels like and I NEVER right reviews, but I just had to for this. I am a solid DIYer. I've struggled with hole bits many times over the years and never have I had the easy, quickness and success this pack has given me! The pictures above were taken off the very first attempt at using this kit. As you can see, PERFECTION!! Can't say enough about it. Need to make some holes in something, get these!!

JIG WILL NOT STICK TO TILE, BITS WEAR DOWN INSTANTLY, TOTAL JUNK

I was so excited to receive the package, it was not well packed but the bits were exactly what I needed. I chose this item as it had a clamp to secure the bit is in one place. the unfortunate thing is that it did not stick to a 2x4 I was cutting into so I had to create a work around with c clamps. I got the job done but the ball bearings kept unscrewing from the base. this could of caused an injury and it happen on 3 of the 4 wheels. Great idea just not well constructed.

I’ve been using this item on Stained glass (art glass). Results were very good.I used a drill press with a water bath covering the cutting area.This has been a great addition to my glass studio.

I had to cut two different size hole in porcelain tile and this kit worked flawlessly. Big box store wanted $35 each without a guide for the hole saws.
