Sabre Tools SDS Plus 1/4" x 6" 10 Pack

arrived on time as described

I've only driven half a dozen holes so far but the bits seem to be of decent quality, the 6th hole was made as easily as the first but time will tell how they hold up. Regardless, for the price I don't think you can go wrong.

Normally buy these in individuals from another brand. These come bundle with multiple and work as well as any SDS bits we have used, plus they are a much better value. We will keep purchasing them. They are being used to drill holes in granite memorials.

Not sure how long a carbide bit is supposed to last but I got about 3, 3 1/2" holes in brick before the bit stopped cutting and I had to switch to a new bit.

Use with my Ryobi rotary drill, cut like butter.

so far i have not had any issues with the bits and they seem to be well made and work good. i have only used to drill about 10 holes but so far so good. product came fast and just as described

drills holes in concrete good

Typical Red China fabrication quality. Do not "push" them beyond simple limits.
