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

A well fabricated tool but it did not fit my hammer drill as the Amazon AI stated it would.

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.

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.

Great bit

It will take about 30 seconds to bore a small hole with this bit. It might take a bit longer through solid concrete but that's stating the obvious. This bit was not worthy of 5 stars though. There is a small pin which holds the centering bit in place. To remove this tiny piny requires the removal of a rubber ring and this pin is hard to notice when it falls out. I also worry about the rubber ring wearing out after time. Seems like a design flaw for something so expensive. But the bit itself work great so far.

Esta broca es perfecta para la instalación de aire acondicionado

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

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

Excelente Producto. pude hacer perfecto el orificio que necesitaba. excelente calidad.

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.

Excelente producto de muy alta calidad lo usare para meter tuveria eléctrica gruesa y para minisplit para sacar ductos y alambrado

This 80mm core bit sdsmax, is an essential drill bit for concreting 4/2 timber into stone. Only problem is, you cannot remove head/ doesn't have holes in the top of the heaf to remove stone out of it. Love to test an improved version, if they ever sell one.
