Will this bit work in my older SDS Bulldog Supreme (not a plus model)

Asked by: Trish
Thank you for your question. The SDS-Plus bits will work with any of our SDS Plus rotary hammer or the old style SDS hammers. They will not work with the large SDS-Max hammers. All of the Bulldog models will accept SDS-Plus.

Bulldog Xtreme 1/2 in. x 4 in. x 6 in. SDS-plus Carbide Rotary Hammer Drill Bit is rated 4.4 out of 5 by 64.

I used this to drill some holes in an old concrete slab that I was installing a door threshold on. I almost burned up the bit using a standard drill because I didn’t have a hammer drill. Once, I borrowed a hammer drill, it went through the concrete with less effort than I thought it would take. After drilling four holes, the bit doesn’t have a scratch on it.

Rated 3 out of 5 by from It worked, just not very long Drilled 8 holes into concrete before the bit wore out. I'm not an expert, but it seemed a mediocre performance at best.
