> 3 dayUsed for installing a kitchen hood unit air exhaust in side of house. Only used once. Did the job well. Nice clean cut. Perfect 6” hole. Can’t attest to longevity as this was a one and done use for me. But based on my experience, I would recommend!

SHARP SAWThe sharp teeth is HSS M42 Bi-metal saw,it can open hole in shorter time with neat opening. |
BETTER CENTER DRILL BITThe center drill bit is higher quality, sharp with split tip, it can drill the holes very fast. and stronger. |
OPERATIONThe shank is 3/8 inch, it is good for most of the hammer drill.Please be sure to tighten the thread between arbor and hole saw when assembling. |
