This is a very good hole saw kit. I used this kit to cut a hole in an outside Metal electric box and it did it fast and the saw blade is still sharp.
Cut smooth, clean, accurate holes contains 8 cutting blades Cut holes for doors, in counter tops and any hobby that needs a perfectly round hole! This kit is brand new and comes in a molded storage case.
