Greenlee 925-7/8 – Frequently Asked Questions
1) Will the Greenlee 925-7/8 hole saw fit a standard drill chuck?
The 925-7/8 Ultra Cutter has a 3/8 inch shank, so it mounts in any standard 3/8 inch or larger drill chuck. No special arbor or adapter is needed, which is why it works off a corded drill, a cordless drill, or a drill press.
2) What size hole does the Greenlee 925 Ultra Cutter cut, and is 7/8 inch the right size for 1/2 inch conduit?
It cuts a 7/8 inch hole. That is the standard knockout size for 1/2 inch trade size conduit fittings, so it is the one electricians reach for when adding a connector to a junction box or enclosure.
3) Do I need a separate pilot drill or arbor with this Greenlee ultra cutter?
No. The 925-7/8 is a one piece cutter machined from solid high-speed steel with a split point pilot drill built in. You chuck it and go. There is no separate arbor, pilot bit, or retaining pin to buy or lose.
4) How does an ultra cutter differ from a regular bi-metal hole saw?
A bi-metal hole saw is a thin welded band with a separate arbor and pilot bit, and the slug usually jams in the cup. The Greenlee Ultra Cutter is machined from one piece of high-speed steel with precision-ground teeth, so there are no teeth to strip off a band, and a spring-loaded slug ejector pushes the plug out on its own. For repeat holes in enclosures, boxes, and sheet steel it is the faster tool; for deep cuts in wood or thick stock a conventional deep-cup hole saw still has more depth.
5) Will this leave a clean enough hole to seat a conduit connector without deburring?
The teeth are precision ground to cut burr-free, so in sheet metal the hole normally takes a connector straight off the tool. Greenlee still calls for a final inspection and a light deburr if the edge needs it, which is worth doing on heavier gauge stock.
6) Can I use the Greenlee 925 hole saw on sheet metal ductwork and enclosures?
Yes. High-speed steel construction and ground teeth suit it to sheet metal work, and Greenlee lists electrical conduit and junction box installs, HVAC ductwork and ventilation connections, plumbing fittings, and equipment mounting or access holes as its intended jobs. Run it at moderate speed with steady pressure rather than leaning on it.
7) Is the Greenlee 925-7/8 made in the USA?
Yes, country of origin is the United States. That matters on public and federally funded work where domestic sourcing is part of the procurement spec.
8) What part number do I order to standardize the 7/8 inch size across my crews?
Order Greenlee 925-7/8. The size is built into the part number, so the rest of the 925 Ultra Cutter family follows the same pattern by hole diameter, which makes it easy to build a kit of sizes for a truck or a tool crib.
