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

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.
