Questions & Answers


Can these be used with a normal hammer drill??

Asked by Pep3504 July 30, 2018

This is an SDS+ But designed for use in SDS applications such as rotary hammers, this is not designed to be used in typical hammer drills. Bosch makes a bit line for regular drills that does wonderfully on concrete.

how long does this bit last?

Asked by ae954426 September 9, 2018

I don't know. I have drilled about 20+ holes through 12" hard concrete and can still drill a lot more. The wear doesn't seen noticeable.

Do you have to have a SDS hammer drill to use this bit

Asked by Handyman March 12, 2019

Yes because you need the hammer action to make this drill bit work best...and it works great in granite!!!

Paired with my DeWalt DCH133 Rotary Hammer, this bit had zero issue boring through 16 year old reinforced concrete. It was like cutting through warm butter with a hot knife.
