Customer Reviews for Bosch 2-1/4 in. x 7 in. x 12 in. SDS-max Carbide Rotary Hammer Core Bit for Masonry and Concrete Drilling

If you need to core holes without hiring or renting large expensive equipment this is your bit. It cored an accurate hole through cured concrete with ease. Seems well built and able to with stand the rigors of daily use. The pilot bit is inexpensive to replace if you do hit some rebar or steel with it. I really like these core bits. I use them to core holes for these solar light pods.

Works really well.

Needed a 2" bit to go through brick and concrete to run a new 1-1/4" natural gas line. This bit worked perfectly! Nice, clean 2" hole in a matter of seconds using my Dewalt cordless SDS max rotary hammer tool.

I drilled through 2 ft of concrete putting a new drain in with this, you will need a chisel bit but I could move about 1/2-1 inch a minute with it working fast with the Bosch 11241evs hammer drill and flipping back and forth between the bits

Great Core Bit. I would buy another when and if this one fails.

Smooth cut.
