### ⭐⭐⭐⭐⭐ Worked very well on my one time use. But be careful.
*by J***E on September 10, 2020*

Task: Move my dryer vent lower, through a wall made of a row of concrete block faced with full brick, so about 11.5" - 12" thick.Skill level: fairly accomplished home handyman, comfortable with power tools. I had never done this before though.Solution: this bit with a [ https://www.amazon.com/gp/product/B00DHJK9JS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 ] adapter and a 9 amp Chicago Electric 1/2" D handle drill. This is a rotary drill, NOT a hammer drill.I started by drilling a 1/4" hole all the way through from the inside so I knew exactly where to drill from the outside. This also allowed me to place the hole in the center of the void of the concrete block, which makes drilling faster and easier.I DID have to make a template out of a piece of 2 x 6 lumber with a 4.125" hole to hold the 4" bit in place to start it. I already had a 4.125" hole saw. You may need to buy one, or perhaps an adapter with a pilot bit. I temporarily attached the wood template to the brick with a couple tapcons.I started drilling very carefully, using a torpedo level on the bit occasionally to stay fairly level. I also poured a little water on it occasionally - I don't know if that mattered or not.MY learning curve - I knew if the bit bound up I could be injured - these bigger drills are no toy. So I was attempting to be super careful. Regardless experience is the best teacher. I had only used this particular drill once before (all day though, to mix many bags of mortar in a bucket. I drove it so hard it smoked bad and it still works great).The drill is varible speed so, paying close attention, when I felt it start to bind I'd slow or stop, feeling my way. But! at one point I had accidentally engaged the trigger lock. So it stars to bind, I back off the trigger, it still runs full speed. 'Bapping' my hands a few times until it fell out of the hole and on the ground, still writhing around like a wounded snake, until I could pull the plug.It could have been way worse. I have a smallish bruise on one forearm and a large bruise on the outside of one hand, with a little soreness in the wrist holding the d handle. I consider myself lucky. Be careful!No damage to the house, the drill, or the bit. It broke the wood template in two. It twisted and bent the adapter pretty badly (!) but I managed to straighten it out enough to finish with no further issues.With an eye on that dam trigger lock, I proceeded through the brick (that was the slowest going) and into the first side of the concrete block. Then I pulled the drill out and knocked the brick off, which gave me more depth / room for the bit, which is how I drilled deeper than the 9" length of the bit. I hope I explained that clearly.Then completed the hole.Result: this bit worked perfectly. It appears to have more life left in it too. It took about 30 minutes including binding. It takes some muscle but not too bad.Verdict - many thumbs up!

### ⭐⭐⭐⭐⭐ Drilled great through brick and cinder block wall!
*by S***N on January 9, 2025*

I bought this drill to route a 1" exhaust out of my garage. This drill was the 1 1/4" model that doesnt have a pilot bit in the center. I already had a short 1 1/4" core drill that I used for a tile job years ago, so I used that to start the hole in the brick. As soon as I got about an inch into the brick, I switched to this core drill. It doesn't drill super fast, but it makes steady progress and leaves a really smooth hole. I've drilled two holes with this core drill so far and it has held up really good. Another plus is that it doesn't blow out the exit hole. The exit was clean as the entrance.

### ⭐⭐⭐⭐ Get the job done
*by B***S on February 16, 2025*

I use to core holes in curbs for drainage systems. The work great but only last about 10 holes before they wear out
