FYARES 20PCS Plus Rotary Hammer Drill Bits, Concrete Masonry Hole Tool,SDS+ YG8C Carbide Tip,for Steel/Copper/Aluminum Alloy

Sizes are metric. The packaging that says it includes a drill that is 1/2", but it is actually 12mm - and marked 15/32" on the bit. The hole I drilled with the 15/32" was too small for a 1/2" bolt. Do not buy if you need fractional bits.

Do yourself a favor and write down all the bit sizes included--it's not as good as you might think. They do look like they are made pretty good. Haven't used any just yet-but was really confused at the sizes when I opened the box. An example--5/16--1 at 4"--2 at 6" an1 at 8". Another couple examples--9/16-1 at 8" and one at 10". No short bits below 9/16". Then there is the 23/32--at 18" guess that's instead of 3/4" and 25/32" at 18" guess that instead of 7/8. So all in all-not that happy with the variety at all.

Bits are not true to size, used to install tapcons in concrete the holes are to big. Going to keep them for drilling miscellaneous holes. Bits work well through concrete so far.

Great value, but can’t speak to durability just yet. Arrived quickly and provides numerous sizes to choose from.

This product is great. It worked as described. If future needs, i will buy it again

perfect

Excelente producto.

I have broken four bits so far on one job.
