Metallics OB50691T – Frequently Asked Questions
1) Does the Metallics OB50691T hole saw include an arbor or pilot bit?
The OB50691T is the 7/8 inch saw cup only. You order the arbor and pilot drill separately. At 7/8 inch the saw falls in the small-diameter range, so it takes a small arbor rather than the larger-diameter mandrel used above about 1-1/4 inch.
2) What size hole does the Metallics OB50691T bi-metal hole saw cut?
The OB50691T is a 7/8 inch (22mm) titanium bi-metal hole saw. That diameter is the common cut for 1/2 inch rigid conduit and EMT connector openings in a sheet metal enclosure or panel.
3) Should I use a bi-metal hole saw or a knockout punch for a 7/8 inch conduit opening?
For a new opening in a thin-gauge enclosure a knockout punch gives a cleaner, faster hole with no chips inside the box. The 7/8 inch bi-metal saw is what you reach for when you cannot get a punch behind the panel, when the box is already mounted and populated, or when you are cutting something a punch will not handle such as thicker plate, wood, or a fiberglass enclosure.
4) Is the 7/8 inch Metallics hole saw bi-metal or carbide?
It is a titanium bi-metal saw, meaning a high speed steel cutting edge welded to a flexible alloy backing with a titanium coating. That construction is what lets it cut steel and stainless enclosures as well as aluminum and wood, rather than being limited to soft materials like a plain carbon steel saw.
