This Hole Saw Attachment is junk .It broke within the first 2 uses and rendered my whole project useless. The only good thing about it is that it is in the "Industrial and Scientific" category. The cons, however, outweigh any potential pros. Don't bother wasting your time or money on this product..
Pros
Sharp and durable teeth for smooth cuts.
Cons
Requires specific tool compatibility for attachment.
This hole saw attachment is a complete waste of money... It failed to make clean cuts and often got stuck in the material. It's not durable and didn't work well on thicker metal. The only good thing about it is the price, but that`s not worth sacrificing quality for. Definitely not recommended for any industrial or scientific cutting needs..
Pros
Affordable price
Cons
Failed to make clean cuts, not durable on thicker materials.
This review may not be the most honest one, just because although the box says with the mandrel attached and shown in the picture the hole saw was not included with me :(
