BOSCH HC8526 2-5/8 in. x 22 in. SDS-Max Rotary Hammer Core Bit Ideal for Applications in Concrete

I bought a Bosch drill bit because I had previously dealt with this company. I had used their tools, which unfortunately were not as good as other brands and that is why I gave up on them, but the drill bit met my expectations, it is durable, works well in concrete and normally also copes with stone. I drilled holes for mounting fence posts, it worked quite well, small wear after drilling 16 holes in stone. I recommend, it is worth considering

Last for long time good quality. Several bore holes performed and bit keeps going.

Worked like a charm. Cut through a 12" retaining wall. 4" then chisel, 4" then chisel...ect. It's definitely the most expensive bit I have but man, having the right tool is worth it. Plus it from Bosch. Quailty. ps.. was lucky enough not to hit rebar but I had a bit for that just in case. I was living right that day.

This bit and others I have purchased like it work as they should. These bits will not drill dozens of holes in old concrete. Your lucky if you get 5 or 6 holes out of one bit. The pilot bit may break or the retainer pin may break or fall out, this is not necessarily a failure caused by a defect in the bit. This bit is not magic, it drills holes in concrete of many different designs. It will drill through steel rebar but needs to be done carefully and dulls the bit significantly, so use a rebar cutting bit at these areas if you can. It frustrates me to see people give three stars or less for this bit as it is worth every penny and I consider myself lucky to have access to these. These drill bits are money makers if you bid your job correctly. Just my opinion.

How to drill a 4-in hole in brick and then 3 in in concrete, this thing made a perfect hole very clean no issues but the teeth are already ground down after only one hole would probably work for a few more but at that price I would like it to last longer or to be cheaper.

Chews through concrete with ease and keeps a sharp cutting edge as expected from Bosch products.

I looked at one of these years ago in Canada and it was out of my price range. so when I bid a job to do a heat pump through an adobe wall I was expecting this to cost me much more. the core bit made quick work of the wall, concrete would be a little more time consuming and harder on the gear, but I still feel that it would be able to break through easily. I don't need to talk about the durability because it's Bosch and should last until my children use it anyway. but the price was great.

Como cuchillo en mantequilla

Wow, drilled through 4 inches of concrete in under 2 minutes.

El producto cumple con lo que describe, el precio es un poco alto pero considero lo vale, puesto que se nota la calidad con que se fabricó.
