Greenlee 825 1-1/8 in. Hole Saw

This Greenlee 825 hole saw cuts steel with a 1-1/8 inch diameter bi-metal blade. Variable 4/6 teeth per inch provide efficient material removal for trade professionals. The arbor is sold separately, requiring a compatible shank for your drill. Maximum cutting depth reaches 1-5/8 inch for through-hole work.

Users Needing Complete Kit

Electricians and mechanics who need an arbor included should look elsewhere because this package contains only the saw cylinder. Builders requiring impact-rated accessories for hammer drills cannot use this model as it lacks that rating. Shops needing multiple diameters must purchase each size individually.

1-1/8 Inch Cutting Diameter

The 1-1/8 inch saw diameter determines the exact hole size produced in steel plate or pipe. Verify this measurement matches your conduit, pipe or fastener specification before ordering. An incorrect diameter means the finished hole will not fit the intended hardware.

Questions about this item

Which Greenlee 825 hole saw diameter suits my project?

The Greenlee 825 model offered here has a 1-1/8 in. cutting diameter and a 1 5/8 in. maximum cutting depth, so choose it when you need that exact hole size in steel.

What does the 4/6 variable pitch deliver when drilling steel?

The alternating 4/6 teeth per inch reduce vibration and clear chips faster, giving smoother cuts in steel without the chatter common on constant-pitch saws.

What shank sizes does the 825 accept and what does that limit?

The saw fits 1/4 in., 5/16 in. and 7/16 in. arbors, so your drill chuck or arbor must match one of those three shank diameters to run it.
