Customer Reviews for VEVOR Core Drill Bit, 2.5" Wet/Dry Diamond Core Drill Bits for Brick and Block, Concrete Core Drill Bit with Pilot Bit Adapter and Saw Blade, 9.5" Drilling Depth, 5/8"-11 Inner Thread, Laser Welding
Well, not really sure how good the bit is, because when I got it out of the box to use it, it only had a 5/8" arbor and won't fit the vevor core drill i bought.
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
