Ideal Industries 36-301 – Frequently Asked Questions

1) Will the Ideal TKO 7/8 inch carbide hole cutter cut stainless steel, or just mild sheet metal?
Stainless is within its intended use. The TKO carbide-tipped cutter is built for sheet metal and stainless steel panels, with precision ground carbide teeth that hold an edge longer than standard steel cutters and run with less heat buildup in stainless. Typical stainless work includes food service equipment panels and marine applications.
2) Do I need a separate arbor or mandrel to use this Ideal TKO hole cutter in my drill?
No separate arbor to buy. The 7/8 inch TKO cutter is an integrated arbor design, so the shank is part of the cutter. It chucks straight into the drill, and because there is no arbor joint there is no wobble from a loose connection. A SmoothStart pilot drill is built in as well, so you do not need a separate center bit.
3) Is 7/8 inch the right hole size for 1/2 inch conduit knockouts in an electrical box?
7/8 inch (22.2mm) is the standard knockout size used for 1/2 inch trade size conduit and connectors, which is why this cutter is sized that way for electrical box and enclosure work, conduit entry, and cable pass-through points. If you are running 3/4 inch conduit, you need a 1-1/8 inch cutter instead.
4) Will this cutter punch through and damage what is behind the panel I am drilling?
There is a built-in over drill flange that stops the cutter from travelling past the thickness of the sheet. Once the hole is through, the flange bottoms out on the face of the panel instead of plunging. That is what makes it workable on enclosures, ductwork and equipment panels where wiring or components sit close behind the skin.
5) How do I keep a hole cutter from walking when I start it on a smooth steel panel?
That is what the SmoothStart pilot drill on the TKO cutter handles. Center punch or mark your location, set the pilot on the mark, and start at a moderate speed so the carbide teeth establish a cutting pattern before you lean on it. Then keep steady pressure and a consistent speed rather than forcing it. Chucking it square and tight in the drill matters too, since an off-center grip is the other cause of wander.
6) What model number do I order for the Ideal TKO 7/8 inch carbide hole cutter?
Order Ideal Industries 36-301. That is the 7/8 inch size in the TKO carbide-tipped hole cutter line, supplied as a single cutter with the arbor and pilot drill integrated into it.
7) Is a carbide hole cutter worth it over a bi-metal hole saw for electrical panel work?
For sheet metal and stainless it is a different tool, not just a nicer one. Carbide teeth keep a sharp edge far longer than steel in stainless and generate less heat, so you get clean holes instead of a work-hardened rim and a cooked saw. The trade-off is that the TKO is purpose-built for sheet goods, with a depth-limiting flange, so it is not the tool for deep stock or wood framing. For repeat conduit and enclosure openings in steel and stainless panels, it is the right pick.
8) Does this leave a burred edge I will have to deburr before pulling wire?
The carbide tooth geometry is ground for clean, burr-free holes, which is the point of a carbide cutter over a bi-metal hole saw in thin steel. Ideal still calls for cleaning the hole edges after removing the cutter so the connector or grommet seats properly, so plan on a quick pass with a deburring tool on anything a conductor will pass through.
