Ultimate Handyman | JCB diamond Tech hole saw review @ultimatehandyman | Uploaded August 2018 | Updated October 2024, 6 days ago.
In this video I review a JCB diamond Tech hole saw by using it to drill holes in a tough granite tile. The JCB diamond Tech hole saws can be used to drill tough materials such as grade 5 porcelain, ceramic, granite, marble, glass, etc. I have to say that I was not expecting to drill quite so many holes and wasted a couple of hours doing this test!

I bought the drill bit from here (I’m not on commission)- toolstation.com/shop/Power+Tool+Accessories/d80/Holesaws/sd1530/JCB+Diamond+Tech+Holesaw/p84690
