Ideal Industries 36-550 – Frequently Asked Questions
1) What sizes does the IDEAL bi-metal hole saw come in?
Cutting diameters run from 3-3/4 inch up through 5-1/2 inch: 3-3/4 (36-550), 3-7/8 (36-551), 4 (36-552), 4-1/8 (36-553), 4-1/4 (36-554), 4-3/8 (36-555), 4-1/2 (36-556), 4-3/4 (36-557), 5 (36-558) and 5-1/2 inch (36-559). Order by the diameter you need to cut, since each size is its own part number.
2) How thick a material can these IDEAL hole saws cut through in one pass?
Depth of cut is 1-7/8 inches. That covers sheet metal, panel walls, junction box knockout work and stacked drywall in a single pass. Anything deeper than 1-7/8 inches means cutting from both sides or stepping to an arbor extension.
3) Will a bi-metal hole saw hold up cutting steel enclosures and strut, or do I need carbide?
These IDEAL saws are M42 high speed steel with 8 percent premium cobalt, which is the grade you want for steel enclosures, panel boards and other metal. The 4/6 variable pitch with fleem ground teeth keeps the cut from grabbing in thin gauge stock. For masonry or cast concrete you would step off bi-metal entirely.
4) How do you get the slug out of these IDEAL hole saws without prying it?
Two features handle it. Diamond-shaped side slots let you drive the plug out from the side, and on the 2 inch through 6 inch saws the solid back plate carries cats eye openings so you can punch the slug from behind. Every diameter offered here, 3-3/4 inch up to 5-1/2 inch, falls inside both of those ranges.
5) What diameter hole saw do I need for 3 inch and 4 inch conduit?
Size the saw to the outside diameter of the fitting, not the trade size. The range here covers the common large-bore electrical work: 3-3/4, 3-7/8, 4, 4-1/8, 4-1/4, 4-3/8, 4-1/2, 4-3/4, 5 and 5-1/2 inch. Measure the hub or connector OD and pick the matching diameter, since the increments step in eighths through most of the range.
6) Why does the back plate matter on a large hole saw?
At 3-3/4 inches and above the cup wants to flex and chatter, which is what wanders the cut and strips teeth. The rigid solid steel back plate on these IDEAL saws keeps the cup true against the arbor under that load, and it is the same plate that carries the cats eye slug-knockout openings.
