Poor quality

Bought 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.

I needed this hole saw for an at home DIY project and it met my needs with no problems. Having sold/used commercial brand hole saws in my prior life I can tell you this saw and arbor are not the same quality as the red box or blue/white box products, but you are also talking a fraction of the price. Overall I am happy with this product. It fit my needs for a one time DIY project at a very affordable price & I would recommend it to a friend with similar needs.

Had everything I needed and worked perfectly. REALLY liked the spring that ejected the cut out plywood. Highly recommend this.

Used 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!

I really cant complain, it made a 6 in hole as advertised. Its a cheap hole saw, if you only need to make a couple of holes this is the cockford ollie, if you need to have a 6 in hole saw for actual day in and out work, I would look elsewhere.

The threaded hole for the center bit was tapped crooked. Completely unusable.

Just an fyi need a 1/2 chuck to get this to work. 12v tools dont fit.

Not the highest quality, looked like it may be a second. But it worked good to cut the holes in 1/2 in plywood.
