      • Bosch tough!

      This is one tough bit that drills thru concrete with little to no real effort & gets it done in short order. I've used other smaller diameter Bosch carbide rotary bits for years & their holding up well to whatever I need to drill into. I had a project where I needed to drill to many 1 1/2" holes to count into solid concrete. Before commencing, I scanned concrete surface to ensure there wasn't any re-bar where the holes needed to be (this isn't meant to drill thru steel). While drilling the 1st hole, I was pleasantly surprised with just how fast I was able to drill 4" by just letting my SDS-Max hammer drill combined with this bit to do their thing. Needless to say all the holes were drilled in less than 1/2 the time I had allotted which allowing me to complete project in 1 day VS 2. The bit showed very little wear & tear, so I know it should last my lifetime, just like my other Bosch bits.
