We have started using these core bits with a hope and a prayer and so far they worked out extremely well for some large jobs that they have been used on. No complaints regarding quality or premature failure and we know core drills are highly abused on rentals on job sites. So far so good.
Great core drill. 18 holes through an 8" block pored solid, and still has teeth at 50%. Half the price of name brand!!!
I bought the 2.5 inch core drill to make a hole for a 2 inch pvc pipe through the floor of my basement. Then I installed a Vivosun ducted fan to use as a radon pump. Works great and very cheep. It took probably half an hour of drilling to go through an 8 inch slab of concrete (with wire in it) using a battery powered drill, but it did the job. I used a water bottle to keep water in the hole and wash the mud out. Didn't take much water to keep the bit cool at the slow speed I was drilling.
I drilled 26 hole that ranged from 6” to 9” in concrete with rebar before had to get a new one. I did buy the same one.
Got the job done
Used one time and teeth bent and broke off. Spend a few dollars more on a better product
Worked great and was deliver the next day!
Long lasting and built strong. Great value for the money!
Good quality core bit. I used it for Coring holes for interlock project for landscape lights. Works good and did about 45 holes no problems. Good price and quality.
Awesome coring but for the price. I needed it to drill 8 inch concrete. Did the job good and still looks like you can drill another 10 holes. Took me 4 hours but it was mostly because my rotary drill was a little small and kept overheating.
Wasn’t sure how to attach this to a drill but found a socket that fit over the hexagonal end. Bought an adapter to get to a size my cordless drill could fit. - the bit worked good to provide the hole needed in a concrete driveway.
Used these bits to dry core through one course of brick and 8 inches of reinforced concrete. Was able to complete 36 holes before the core drill shifted during drilling and dented the bit causing it to drill off center. I'm sure it would have done more if we hadn't bent the bit.
I have used the 2.5" version to drill through a 22" thick retaining wall enforced with rebars. The bit had no issues and still has about ⅓ of diamonds left. Go slow and use water cooling. The price is right.
