Ideal Industries 36-300 – Frequently Asked Questions

1) What hole sizes does the Ideal TKO carbide-tipped hole cutter come in?
Ten diameters, each a separate cutter: 3/4 inch (36-300), 7/8 inch (36-301), 1 inch (36-302), 1-1/8 inch (36-303), 1-1/4 inch (36-304), 1-3/8 inch (36-305), 1-7/16 inch (36-306), 1-1/2 inch (36-307), 1-3/4 inch (36-308) and 2 inch (36-309). Each cutter is a single fixed diameter with its own integrated arbor and pilot drill, so pick the size by the fitting you are landing.
2) Which TKO hole cutter size do I need for 1/2 inch and 3/4 inch conduit?
Standard knockout sizes are 7/8 inch for 1/2 inch trade size conduit and 1-1/8 inch for 3/4 inch conduit, which matches the 36-301 and 36-303 cutters. For 1 inch conduit the knockout is 1-3/8 inch, covered by 36-305. If you are enlarging an existing knockout rather than cutting fresh, step up to the next size in the range.
3) Will this cutter go through a stainless steel enclosure, or is it only good for painted steel panels?
The carbide teeth are rated for stainless steel as well as ordinary sheet metal, which is why it gets used on industrial enclosures where a bi-metal hole saw burns up. It is a sheet metal tool though, not a plate or structural cutter, and the over drill flange stops penetration past the sheet thickness.
4) Do I need a separate arbor or pilot bit to use the Ideal TKO hole cutter?
No separate arbor or pilot. The arbor is integrated into the cutter and the SmoothStart pilot drill is built in, so it chucks straight into a drill. That also means you cannot swap cutter heads on one arbor the way you do with a hole saw kit, so each diameter you need is its own tool.
5) Will it walk on a smooth panel face when I start the cut?
That is what the SmoothStart pilot drill is for, it bites and locates the center before the carbide teeth engage, so the hole lands where you marked it on a slick painted or stainless panel face. Start at moderate speed and let the teeth come into the material gradually.
6) Is the hole clean enough to land a connector without deburring?
The teeth are precision ground and produce clean, burr-free holes, which is the point of using it on a live panel where you cannot easily file swarf out. Back the workpiece up so the sheet does not deform on breakthrough and the fitting will seat.
7) What is the largest hole this Ideal cutter will make in a panel?
Two inches, the 36-309. Above that you are outside the TKO range and into a knockout punch set. The 1-7/16 inch size (36-306) is worth knowing about too, it is the odd one in the lineup and matches openings a straight fractional saw misses.
8) Can I use this to add a conduit entry to an energized panel already mounted on the wall?
It is built for exactly that kind of retrofit, adding new connections to existing panels and enclosures, and the over drill flange limits how far the cutter travels past the sheet so you are not driving into the gutter behind it. Mark with clearance from existing components and confirm the panel is de-energized before drilling.
