Review: Good core drill. Lasts much longer than expected for a cheaper off-brand. - I have used two of Sali's 1in diamond concrete core bits, one for a personal project, and the other for commercial electrical work, both with very good, very acceptable results. Do yourself a favor and purchased the recommended drill arbors (adapters). My boss insisted we likely had adaptors somewhere even after I assured him we didnt have these, let alone the 5/8-11. We ended up having to order them later further delaying the task and causing undue frustration. I wouldn't be surprised if these cheaper off brand bits have less diamond in them than more expensive name brands but for the price and my experience they were still a good value. Experience generally proves if you need to rely on a tool for commercial work, need to complete numerous jobs, and need to get a job done asap then buy a name brand because you will get what you pay for. If you just need to complete a small project and may not use it again or for years, get a cheaper value brand. So far this brand seems like a medium compromise. *The first bit I purchased 3 years ago in 2022 for a home project that required 50 holes for termite mitigation. I used the diamond core bit to easily drill the last 5 holes in 12in thick concrete with rebar. I struggled with some of the holes and especially the last 5 holes using a Milwaukee 1in 4-way tip rebar hammer drill bit and even purchased a newer slightly harder-hitting drill. After much frustration, I postponed the project until I received this Sali 1in diamond core bit. It was so much easier going through the rebar. I made certain I didnt force the bit too hard through the revar to avoid breaking the teeth. *The second bit, I talked my boss into getting where rebar was giving us trouble with rebar hammer drill bits. While I wasn't the only one to use this bit at work, I know it drilled a fair number of holes before me and a coworker used it up on a very difficult project which broke off one tooth and then subsequently worked until it completely wore off the diamond teeth after about 35 minutes of abuse. In the end this bit was still worth every penny. In this case the diamond bit was able to cut through a 3/4in piece of rebar still poking into the messy oversized hole that the hammer drill bit would just bounce off and sometimes jamb on. The second I talked my boss into buying September 2025 for commercial electrical work. (At work, its consistent they have no real clue how long holes take to drill 10-12in deep rebar reinforced concrete holes, and are too anal and cheap. They would rather buy a $90 hammer drill bit and then pay us $140-$280 in labor plus more tool wear using the wrong bits for the job at hand and get done in 1hr.) Use the correct tool for the job and save headaches and time. For plain concrete and masonry, a hammer drill bit is a better value and can drill more holes overall, but where the hole entrance and exit appearance are less important. Use a diamond core in rebar-reinforced concrete and where the hole appearance matters. Hammer drill bits take a long time, create silica dust, and make you more tired, but a diamond bit is much faster, easier, creates little dust, and when used wet doesn't create any dust. The downside with a diamond bit is name brands are somewhat more expensive and you don't get as many holes as a hammer drill bit. Tip: a hammer drill bit can be sharpened with a dremel and a small diamond dremel rotary bit.
Review: Great quality and a cutting beast! - I bought this to install a railing for our swimming pool. It's a small job so I only cut two holes into the concrete surround but it worked just great. This large diameter does make it a challenge to get started without the bit wandering around a bit before it gets the round groove started, particularly since I was doing this hand held without a stand that could be secured to the ground and held in the vertical position. But with a bit of patience I got it started and then could hold it vertical without any trouble. I sluiced the cut with water to keep it cool and clear the debris, it cut through 6" of concrete in about 4-5 minutes for each hole. I was pleased as well to find that it had cut through the steel rebar embedded in the concrete (which I was hoping to find anyway so I could electrically bond the rail to the rebar and the rest of the pool equipment). So I was cutting with a 8.5 amp corded drill and that combo worked great, good control while it was cutting and plenty of power to keep spinning until it got through the full depth. Totally happy with the performance of this bit, would definitely buy it again if I needed to, but the one I bought is still in great shape and I expect it will go for a lot longer. It's a good price for this level of quality--not the cheapest and not the most expensive--saved me a lot of money over hiring the job out since this was such a small project.
