1/4" Masonry Drill Bits 8" SDS Plus Hammer Drill Bit 1/4 inch Concrete Drill Bit for Block, Brick, Stone, 12 Pack

work like they should.

I go through a lot of masonry drill bits when I am working in concrete with my rotohammer. This set of bits really fits my needs, it includes plenty of good quality bits. Working with a drill bit with a dull tip is really a waste of time and even the best quality bits go dull pretty quick. So, it is best to have lots on hand. I would rather use a bit that is in good condition to save time, so I swap them out pretty quickly to get the job done in a timely manner. This set gives me what I need and they are definitely a good value.

I love having smaller diameter bits like this in SDS-plus format, while still having them long enough to easily make holes for tapcons and other fasteners deep enough. God, I hate when your bit is barely long enough and/or it sinks into the jaws of a traditional chuck.These also come in one of those common plastic sleeve cases, but it just happens to fit nicely in my drill's case.
