All good - wanted the 1.25 dia thread instead of the 22mm which seams to be the standard now in metric-was very pleased to find this incn size — will need to look or make adapter to use 22mm core drill bits in my 1.25 machine
The guide bit is useless. Built a rig to line it up. Overall, good value for the money. Have drilled 4 holes through 3 layers of brick each and it's held up well.
Never used this type of core drill. It was very easy to use,went through 8 inches concrete block dry and with not much effort. Very pleased, I needed this hole drilled for mini split ac and it was perfect for the job.
Worked better then some high end bits I have used. Drilled a 5 in core with no issue or hiccups including 2 -1/2 rebars definitely shocked how good it worked for the price I didn't have the best expectations. But I was wrong
It is well made, ate up the concrete slab using a wet core drill. We went with a handheld model, which works great if you have a lot of experience with large drills.
