Hole Cutter · 1-7/16 in (37 mm) Carbide-Tipped · SmoothStart Pilot for Sheet Metal · IDEAL 36-306
What this product is for
The IDEAL 36-306 TKO hole cutter is used to cut a 1-7/16 in (37 mm) hole in sheet metal, including stainless steel and other ferrous or non-ferrous metal enclosures. It is designed for electricians and contractors who need a cleaner alternative to standard hole saws or a faster option than manual knockout setups for light sheet-metal work.
Use for
- Electrical panels and cabinets
- Junction boxes and pull boxes
- Sheet metal enclosures
- Stainless steel and general sheet-metal drilling
- Handheld drills with a 3/8 in chuck or larger
Avoid for
- Material thicker than 1/8 in (3.2 mm)
- Deep cutting applications beyond sheet metal
- Masonry, wood boring, or general-purpose rough cutting
- Applications where a different finished hole size is required for fittings or conduit trade sizes
Best for
Best for electricians cutting repeat holes in metal boxes and enclosures where clean edges, reduced burrs, and controlled cutting depth are important. The built-in pilot and over-drill flange help guide the cutter and limit penetration beyond the sheet metal.
Installed in
Typically used on electrical service work, commercial tenant fit-outs, control panels, retrofit enclosure work, and shop fabrication of metal electrical boxes and cabinets.
Why this product exists
This cutter is made for faster, cleaner hole cutting in sheet metal than many conventional hole saws, while avoiding the setup time of knockout punches in lighter-gauge applications. IDEAL's SmoothStart pilot drill is intended to reduce walking and help protect the carbide cutter during startup.
Compared with similar products
Compared with a bi-metal hole saw, this carbide-tipped cutter is intended for sheet metal and stainless steel cutting with cleaner, more controlled results. Compared with a knockout set, it can be a practical choice when speed and portability matter. As typical trade guidance, use cutting oil to help extend cutter life and improve chip evacuation. Actual performance depends on material type, drill speed, pressure, lubrication, and installation conditions.
