Greenlee 825-13/16 – Frequently Asked Questions

1) Will a Greenlee 825 hole saw cut all the way through a 2x4 stud in one pass?
Yes. The 825 bi-metal hole saw has 1-5/8 inch cutting depth, which takes it through the 1-1/2 inch thickness of a 2x4 wood stud in a single pass without having to back out and re-enter.
2) What arbor do I need for the Greenlee 825 hole saw?
It mounts on an arbor with either a 5/16 inch or 7/16 inch shank, so it works with standard hole saw arbors for a drill or drill press. The arbor and pilot bit are separate items, so order one if you don't already have a matching arbor on the bench.
3) Can the Greenlee 825 bi-metal hole saw cut metal, or is it wood only?
It cuts both. The bi-metal blade is rated for steel, tin, aluminum, fiberglass, wood, and plastic, so the same saw handles a panel knockout, a stud bore, and a fiberglass or plastic penetration. Start slow to establish the cut, then bring the speed up to suit the material.
4) Why a variable pitch hole saw instead of a standard uniform tooth saw?
Variable pitch spaces the teeth unevenly, which breaks up the harmonic that causes grabbing and chatter when you move between material thicknesses. On the Greenlee 825 that is what lets one saw work in thin tin and in a wood stud without changing blades. If you only ever cut one material at one thickness, a fixed pitch saw will do, but for mixed trade work the variable pitch is the reason to buy this one.
5) What does the steam oxide finish on the Greenlee 825 actually do for me?
It runs cooler. Steam oxide cuts heat buildup during long or repeated cuts, which is what kills a bi-metal blade in sheet steel. Paired with the extra-thick backplate, which damps vibration, you get a steadier cut and less chatter when you're boring a run of holes.
