Greenlee GREE-P476794 – Frequently Asked Questions

1) Will the Greenlee 645 carbide hole cutter go through 8 gauge stainless without cutting oil?
Yes. The 645 series carbide-tipped hole cutters are rated to a maximum cutting depth of 8 ga, and the tungsten carbide teeth are designed to cut stainless steel with no oil required. That covers sheet metal enclosures, panels and boxes. Anything thicker than 8 ga is outside what the cutter is rated for, so for heavier plate you need a different cutting method.
2) What size holes can I cut with the Greenlee 645 carbide hole cutter range?
Trade sizes run from 5/8 inch up to 4-1/2 inch. Individual cutters include 7/8 inch (645-7/8), 1-1/8 inch (645-1-1/8), 1-7/32 inch (645-1-7/32), 1-3/8 inch (645-1-3/8), 1-3/4 inch (645-1-3/4) and 2-1/8 inch (645-2-1/8), so the common conduit knockout diameters are covered. The 1-7/32 inch is the one electricians reach for on 1 inch conduit knockouts.
3) Do I have to re-chuck the drill every time I change hole size?
No. The 645 cutters use a quick-change connection, a push-and-turn engagement that lets you swap cutter diameters without pulling the arbor out of the chuck. If you are running several knockout sizes on one enclosure, that is the main time saving over a standard bi-metal hole saw setup.
4) Will a carbide-tipped hole cutter work on aluminum, copper and plastic enclosures, or is it stainless only?
Stainless steel is what the carbide teeth are optimized for, but the same cutter handles mild steel, aluminum, copper, brass, fiberglass and plastics. That makes it a single cutter for mixed work, aluminum gutter and pull boxes one day, stainless washdown enclosures the next.
5) Does the cutter leave a burr I have to file off before installing a connector?
The 645 cuts round, burr-free holes, so in most sheet metal you can set a fitting straight away with minimal deburring. A flange stop prevents over-drilling, which is what usually distorts the hole edge, and a slug ejector spring pops the cut disc out instead of you prying it from the cup.
6) Is a pilot drill included with the Greenlee carbide hole cutter, and does it need a separate arbor?
A split-point cobalt steel pilot drill is part of the assembly, with a step design that centers the cut and needs less push from the operator. The cutter mounts on the quick-change connection rather than a conventional threaded arbor, so keep the matching quick-change adapter with the set if you are ordering cutters individually.
7) What are my alternatives to the Greenlee 645 for cutting a device box opening in sheet metal?
For round holes, the Ideal Industries 36-801 DEADEYE is a 7/8 inch carbide tipped hole cutter, a direct size-for-size alternative to the Greenlee 645-7/8. If what you need is a rectangular single gang opening rather than a round one, neither round cutter will do it. The Rack-A-Tiers 42700 Single Gang Q-Bit cuts a 2-3/8 by 3-3/4 inch single gang opening instead.
