ABuff 4 inch 100 mm Hole Saw with Arbor, Heavy Duty 38mm Depth Bi-Metal HSS 4 Inch Hole Saw Blade with Positive Rake Teeth for Cutting Soft Metal, Drywall, Plastic, Wood, Fiberboard

I used this hole saw to cut two holes in a 3/4 shiplap ceiling for fans. Worked quite well and the teeth on the saw look to be just as sharp as when I started. As others have mentioned it does required a 1/2 inch drill.

Teeth wore done after drilling thru two 1/2 boards. Junk

This hole saw cuts great and overall does a good job. Only reason I gave it a 4 instead of a 5 is because it had a little manufacturing defect and due to time constraints I chose not to send it back. The set screw hole was not properly threaded and the set screw would not hold. I was able to redrill and rethread the hole myself and use a slightly larger set screw. Other than that this hole saw is a good buy.

Hole saw is well made and cuts nicely, but is too shallow to be of any real use when trying to bore through 5/8 or more plywood. If it was just another 1/2 inch deep it would be a fantastic tool, but as it is it will end up in my box of unused but cant bring myself to throw away tools.

I have used other hole saws, and as far as cheap ones go, this is actually quite nice, worked very well, though the shank is quite large, just barely fits the chuck in my drill. Would have been a bit more convenient if it had used a 1/4 shank, then I could have used my standard extensions, which would have been nice, but its not a huge deal.

The product is good quality and comes with multiple bits, however if you want to use it to cut sheet metal holes for HVAC holes this is not a good hole saw to use. Basically the bit just keeps enlarging the pilot hole and the saw itself just mars the surface. Ended up using a jigsaw following the mar the hole saw made. I suspect the teeth are too large.

Was on time Well packaged Did a good job

Nothing

I cut the drywall with my 18V cordless drill which was a little clunky. Love the complete kit and ease of assembly. It would work better if I used the drill with a cord.

As most will tell you, with tools the old adage that you get what you pay for holds very true. I only needed to cut a few holes with it, and it did so more than adequately. For my needs it beats paying over twice as much for a better quality unit.
