Metallics TCT78S – Frequently Asked Questions
1) What size hole does the Metallics TCT78S hole cutter make?
The TCT78S cuts a 7/8 inch hole. That is the standard knockout size for 1/2 inch trade size conduit fittings, so it's the cutter you reach for when you need to add a 1/2 inch connector entry to a box or enclosure.
2) What does the "shallow" 3/16 inch rating on the Metallics TCT78S mean for my cut?
The 3/16 inch refers to the shallow cutting depth of the TCT78S, so it is built for thin stock, sheet metal boxes, enclosure walls and panel sheet rather than thick plate. If you're cutting material deeper than that, this is not the right cutter.
3) Which Metallics part number do I order for a 7/8 inch shallow hole cutter?
Order Metallics TCT78S. It's a single part number, no size or depth options to specify, and it covers the 7/8 inch diameter at the 3/16 inch shallow depth.
4) Is the TCT78S hole cutter for electrical work or general metalworking?
It's an electrical trade tool, catalogued by Metallics for electrical installation work. In practice that means enclosure and box entries for conduit and connectors, which is where the 7/8 inch size comes from.
