Greenlee 50191411 – Frequently Asked Questions

1) What hole diameters does the Greenlee bi-metal variable pitch hole saw come in?
Six hole diameters: 1-1/8, 1-3/8, 2, 2-1/2, 3-5/8 and 4-1/2 inches. The part numbers run 50191411 (1-1/8), 50191462 (1-3/8), 50191551 (2), 50191624 (2-1/2), 50191721 (3-5/8) and 50191802 (4-1/2). Pick by the finished hole you need in the panel or box, not by the conduit trade size alone.
2) Which size hole saw do I use for 3/4 inch conduit?
The 1-1/8 inch hole diameter version, Greenlee 50191411, is the one matched to 3/4 inch conduit. Its cutting size is listed at 1-5/8 inch with a 1-1/8 inch hole diameter and a 3/4 inch pipe tap size, which is the standard entry hole for 3/4 inch trade size fittings.
3) Can I use the same arbor across all the sizes of this Greenlee hole saw?
Yes, the whole range from 1-1/8 inch up to 4-1/2 inch is listed for the Greenlee Quick Change Arbor No. 2800 or Standard Arbor No. 37157, 37155 or 38522. That is useful if you are standardizing a crew's kit: one arbor and pilot bit, a set of cups in the conduit sizes you actually run.
4) Will a bi-metal hole saw cut through a steel electrical enclosure?
Yes. The cup is bi-metal with a variable pitch tooth pattern, which is what lets it cut steel, aluminum and the other sheet materials used in panels, boxes and enclosures. Variable pitch spacing cuts down on chatter when the teeth break through thin gauge metal, so the bore comes out cleaner than with a uniform pitch saw.
5) Is a variable pitch hole saw better than a knockout punch set for conduit openings?
They do different jobs. A knockout punch needs a pilot hole and clear access to both faces of the panel, and it gives the cleanest result in enclosure steel. A bi-metal variable pitch hole saw like this one works from one side only, which is why it gets used on retrofit and rough-in work where you cannot get a draw stud behind the wall of the box. Match the hole diameter (1-1/8 through 4-1/2 inch here) to the fitting and run it on the arbor.
6) Where is this Greenlee hole saw made?
Country of origin is the US. That matters on public and institutional work where domestic sourcing is a procurement condition.
7) What are the overall dimensions of the 1-1/8 inch Greenlee 50191411 hole saw?
The 50191411 is listed at 4.450 inches in length, 1.400 inches in width and 1.050 inches in height, with a cup volume of 6.5415 cubic inches. The 1.050 inch depth is the practical limit: material thicker than that cannot be cut through in a single pass with this cup.
