> 3 dayIf you plan on using this once, you are fine. But it becomes immediately dull. Overseas JUNK.

> 3 dayBoth drill bits supplied snapped immediately only drilling through drywall. Hole saw itself does work decent, but kit is cheap.

> 3 dayBought this for the sole purpose of cutting a specified 4” hole in the bed of my pickup for a B&W turnover gooseneck. It cut the hole in the bed and then I used it to cut a hole in the bed mat (as you can see in the picture). I’m happy with it because it met/exceeded my expectations. If it cuts anything else in the future that’s a bonus.

Greater than one weekBought this to drill holes for corn hole boards I make. Works decent for this task, but I would use it on metal. The spring on the drill is a bit odd and I am not really crazy about it... I honestly dont think it will last so not too worried about it. I am also not too crazy about how the drill holder mounts to the saw portion. The quality of the saw seems good and will last for my needs. Overall, for the price and how I use this, it works fine and I happy with my purchase.

> 3 dayBought this a I had 12 holes to drill in 1/2” drywall to install surface mount LED’s. On 1st hole the bit snapped and damaged my ceiling as it skipped across the ceiling. I sent it back and used a hand drywall saw instead. Wonder what would have happened if I attempted to cut plywood. They did refund me my money.

> 3 day102mm saw worked fine through wood but 4 inch ducts are slightly larger than 102mm. I would recommend buying a slightly larger hole saw for 4 ducts.

> 3 dayThe hole saw is not exactly the 4 inches I needed to put in a exhaust duct on my roof I was able to use the same holesaw and Waller out the hole. For the value it’s not bad you’re just not gonna have a perfectly outside diameter 4 inch hole you’re going to have to work for it. It’s a Chinese tool... I mean lol

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. |
