Review: super drill bit I recommend - 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 Review: BOSCH HC8526 2-5/8 in. x 22 in.

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 ### ⭐⭐⭐⭐⭐ BOSCH HC8526 2-5/8 in. x 22 in. SDS-Max Rotary Hammer Core Bit *by T***E on July 4, 2026* A well fabricated tool but it did not fit my hammer drill as the Amazon AI stated it would. ### ⭐⭐⭐⭐⭐ Great bit, not designed to drill rebar, needs to be used properly, be smart it will last *by J***S on November 6, 2018* 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. ## Frequently Bought Together - BOSCH HC8526 2-5/8 In. x 22 In.
