The media could not be loaded. This Boring bit is AMAZING for the price...I bought many at 3 times the price that did not work as well as this one. I was very impressed with the product, and I was unsure if I was going to get a good quality item from Amazon, BUT IT WORKED SO WELL! SAVED ME SO MUCH MONEY THAN RENTING A BORING DRILL FROM RENTAL COMPANY. So glad I bought this. Will buy again when this wears out. I even got overnight shipping for free with prime! Cut quickly and easily with a 8amp hammer drill

I don’t ever wrote reviews, but this bit was amazing. I’m a landscaper and was a little reluctant to buy a cheaper bit. This bit drilled thru 15 pavers in record time! Very impressive.

I used this for two holes through my cinder block basement wall. I actually thought it was 8inch blocks but turned out to be 10 so glad I got this.I went through the hollow sections of the block and removed the chunk of cement between sections. I used a regular 20v drill and it was somewhat slow going but certainly could tell it was moving gradually without a lot of pressure.Even if I don't use it again, it's a great deal. Very happy with the results.It was a little difficult getting the initial bite of the wall, it wanted to walk a little bit once I was in it stayed straight.

Used to cut through the length of a brick. That was the orientation of my wall. Getting started was tricky since there is no pilot bit. I started on an edge until a semicircle was formed then lined up for the full cut. A tooth was broken off during the cut, but it kept going. I didnt know until the cut was done. Overall worked well. Glad I purchased it.

I had to drill two 1-1/8” holes from one side in older concrete block (8” CMU) for 3/4” conduit. The holes were located to go across the cores (not filled) so it should be a fairly simple task. Even so, I bought two bits in-case one got worn down. After an hour with my plug-in SDS drill in rotary only on low speed and me and a helper taking turns to keep it pressed into the hole, both bits eventually became unusable after coring only one hole and part of the second.For contrast I finished the job with a big name diamond hole saw - the kind marketed for tile. It cut right through the last block with a beautiful hole in just a couple of minutes using only my battery drill and hardly any effort. I felt pretty dumb for spending time using this core bit.

This thing cuts thru brick like it's warm butter. Saved me soooo much time

Went through brick and cinder wall without issues, I had a nice sdr hammer drill which makes life easier also. Hoping it can make it through some concrete curb this summer. Worth the money for what I needed

Worked great and easily went through 8 inches of cinder block and concrete in a matter of minutes with electric power hand drill. Photos show hole (larger hole on top in photo) and the tool after use.
