Bit is a light weight heavy duty enough for cutting. Threads match the hand held drill great.

It works great drilled in some posts holes into bedrock. Can put it in your normal drill, I use that hammer drill which is not recommended for coring holes.

Aangeschaft om gaten voor spots te boren in mijn oprit tegels. Is goed gegaan. Mooi dat er drie aansluitingen bij zitten

Bit worked very well with Bosch hammer drill!

It worked great

Make sure the adapters compatible with your drill.

This core bit works well and is a great value. As others have said, the center drill is too short but that only affects starting the hole. Once started, the center drill is not necessary. I drilled through a 10" concrete wall, 2" at a time, using a chisel periodically to break off and remove the plug to keep the bit from binding. Definitely use a corded drill.

I bought the 6" drill bit because the HVAC and cement guys told me they didn't have a way to drill through my storm shelter to get air flow. I bought this without any idea what I was doing, and I was pleasantly surprised. It took some time, but I drilled a perfect hole through 10" of concrete with nothing but a Milwaukee hammer drill (which was just as impressive). I don't think they're made to go through rebar, but they eventually went though a couple rods that were in the way as well. I wouldn't be scared to use these core bits on any project.

It’s an amazing package for the price. This comes with drill stems for industrial drills and home drills alike. The center bit can be replaced with a hardened concrete drill and this cuts well into the older hardened concrete to make bolt down holes for anchoring heavy vibration equipment. If you’re doing a job with some serious concrete to get thru this is a great bit. I used it to drill multiple 4.5” deep holes to anchor the weight train for an elevator and it worked perfectly.

Buen producto, ayuda a resolver situaciones y proyectos.
