Greenlee 825 7/8 in Hole Saw
The Greenlee 825 is a 7/8 inch variable-pitch bi-metal hole saw designed for cutting steel. It suits tradespeople and DIY users who need clean holes in metal sheet or plate.
Check arbor and shank compatibility
The saw ships without an arbor and accepts shank sizes of 1/4 in, 5/16 in and 7/16 in. Verify your drill chuck capacity and select a matching arbor before starting the job.
Bi-metal teeth manage heat in steel
Variable 4/6 TPI geometry reduces vibration and helps dissipate heat during steel cutting. The 1 5/8 in maximum cutting depth allows thicker workpieces without excessive feed pressure.

Questions about this item
Does the 825 hole saw come with an arbor or pilot drill, or must I buy them separately?
The saw is sold without an arbor; you need to supply a compatible arbor and a 1/4 in. pilot drill yourself.
Which tooth pitch should I choose for cutting steel with this 7/8 in. saw?
The blade has a fixed 4/6 variable pitch, designed for steel, so no alternative pitch is offered.
What does the 1 5/8 in. maximum cutting depth mean when I am drilling through a steel plate?
You can cut up to 1 5/8 in. deep in a single pass before the saw needs to be cleared.
