Ideal Industries 36-311 – Frequently Asked Questions

1) What sizes come in the Ideal TKO 4-piece carbide hole cutter kit?
The Ideal TKO kit (model 36-311) carries three carbide-tipped cutters, 7/8 inch (36-301), 1-1/8 inch (36-303), and 1-3/8 inch (36-305), plus the SmoothStart pilot bit (36-312) and a carrying case. Those three diameters cover the common knockout sizes an electrician cuts in panels and boxes for 1/2 inch, 3/4 inch, and 1 inch conduit fittings.
2) Will these hole cutters go through a steel load center or just thin sheet metal?
The carbide-tipped teeth are meant for electrical steel and aluminum enclosures, and the description also lists composite enclosures. That covers load centers, junction boxes, and industrial control panels. Start the cut at low speed to seat the pilot, then bring the drill up to cutting speed and let the carbide do the work rather than leaning on it.
3) What does the SmoothStart pilot bit actually do, and do I need it for every cut?
The pilot bit (36-312) centers the cutter and keeps it from walking across the face of an enclosure when the teeth first bite. It installs with the cutter, and you position its point on your marked center before drilling. On a panel door or a box side where you have one shot at hole placement, use it every time.
4) Will the TKO cutters fit my regular drill, or do I need a special arbor?
They mount with standard arbor compatibility for most drill systems, so the selected cutter goes in the drill chuck along with the pilot bit. No dedicated cutting machine is needed.
5) Is a 4-piece kit enough for a telecom or low-voltage rough-in?
For cable entries and equipment mounting openings, the 7/8, 1-1/8, and 1-3/8 inch sizes handle most standard fitting and bushing diameters. Anything larger than 1-3/8 inches, such as a 2 inch conduit knockout, falls outside what this kit covers and needs a bigger cutter or a knockout punch set.
6) Can I buy a single replacement cutter if I wear one out?
Each cutter carries its own Ideal part number, so a worn one is replaced individually: 36-301 for 7/8 inch, 36-303 for 1-1/8 inch, 36-305 for 1-3/8 inch, and 36-312 for the SmoothStart pilot bit. Order by that number rather than the kit number 36-311.
7) Do I need to deburr the holes after cutting with this kit?
Cuts come out burr-free, which matters because a ragged edge shaves insulation off conductors being pulled through. Check the edge after each cut and confirm your connector or fitting seats flat before you pull wire.
