Using a Cheap Amazon Masonry Hole Saw

• I made a second video with this bit drilling through half of a cinder block: https://youtu.be/vs2jcv9F36A

• I had the same idea to try this same kit because I need to drill 1 hole in the side of the house for a electrical lb. I've drilled for about 2 hours, dry at first,then with a mist of water on the bit,and I am barely through the first brick (2 total). The pilot bit goes through like butter on hammer drill but you are only suppose to use the core bit on regular mode and it is taking forever. It seems to cut slightly better with water and I have tried very slow drilling (rpm's) and mid range. I would not personally recommend this kit, but you had better luck than I did.

• We have used this bit to drill roughly 30 holes

• Made in China. ☹

• I have the same thing , however, I lost the pilot bit and nut in the wall. Mine did not come with a lock washer. Perhaps that’s what I need for mine.

• Lock washer just comes right out on these.

• Ok, not bad, especially when you are not doing this everyday, I think it's worth to use a cheaper tool.... and definitely, having a Hilt hammer drill is a big plus !

• Can I use regular impact hammer drill or I need something better?

• Not a good representation as you drilled pilot holes first just my opinion but TCT may well have worn more if you hadn't
