Poorly Made in China

Poorly made in China. The mandrel included in the kit is not suitable for the hole saw. The two pins on the mandrel did not match the two holes in the hole saw mandrel and did not match the other two at all. I bought a Milwaukee gazebo hoping it would be better, but it didn't fit the holes at all. The hole saw appears to be accurate or very close to the actual 6" diameter, but that's about the only good thing I can say about this hole saw. i will return it

Pros
  • Material: M42 High Speed Steel Product Weight: 2.56lbs Mandrel Diameter: 10.95mm/0.43 inch Clockwise rotation
Cons
  • New Competitors Emerged

What a Difference!: Saw Blades, Parts and Accessories

I bought this hole saw about an hour after comparing reviews, features and price. . This seemed like the best all round choice and I can say it worked.

Get what you pay for I guess! I was used to custom holes and just used my sander to smooth out the imperfections. This hole saw cut my holes the way they…

Pros
  • High abrasion resistance, extremely durable and provides fast and clean cuts in the toughest materials
Cons
  • Great Price

Not suitable for Hardi Board or other cementitious boards.

circular saw to install vent through exterior wall, to pull out the oven. When this 6 inch beast arrived I was impressed with its depth and strength as well as the shaft design. In action, it quickly cuts through drywall and OSB. However, when I encountered cementitious hardiplank, the cutting slowed to a minimum and deteriorated when attempting to cut two partially overlapping boards. It was obvious that the teeth were rotten. When the saw wears out after about half an hour or more, the outer…

Pros
  • Cutting holes for plywood, thin sheet iron (within 3mm), acrylic sheets, drywall, air ducts (plumbing except stainless steel), ceiling lights, lamps (not for hard cement board), etc.
Cons
  • Crumpled
