Hole Saw · 1-3/8 in (35 mm) · Tri-Bore carbide-tipped multi-purpose · Ideal Industries 36-350
What this product is for
This 1-3/8 in (35 mm) IDEAL Tri-Bore hole saw is a carbide-tipped multi-purpose cutter for electricians and contractors making holes in abrasive or mixed materials. It is intended for use with compatible IDEAL hole saw arbors and a longer pilot bit because of the deep-cup design.
Use for
Use it for cutting wood with nails, cement board, composite enclosures and ceiling tile. It is commonly selected for electrical rough-in, panel and enclosure modifications, and other trade work where a carbide-tipped hole saw is preferred over a standard bi-metal saw.
Avoid for
Avoid using it as a general-purpose substitute for every metal-cutting application or where the required arbor and pilot are not matched to the saw. For heavy-gauge metal or unsupported materials, confirm the cutting method and accessory compatibility before ordering.
Best for
Best for electricians who need one hole saw for abrasive materials and wood that may contain nails. A typical trade use for a 1-3/8 in saw is creating an opening associated with 1 in conduit work, but this is application guidance only and should be verified against the actual fitting or component being installed.
Installed in
Typically used on site in electrical rooms, commercial tenant fit-outs, service upgrades, panel work, prefab assemblies and general construction where wood, cement board or composite electrical enclosures are being drilled.
Why this product exists
Tri-Bore exists to give the trade a carbide-tipped option for materials that wear out standard hole saws quickly. The deep angled gullets are designed to help with plug removal, and the carbide tooth design is intended for abrasive materials and wood with embedded nails.
Compared with similar products
Compared with a standard bi-metal hole saw, this Tri-Bore model is better suited to abrasive materials such as cement board and composite enclosures. It is also commonly chosen when wood may contain nails. As a rule of thumb, carbide-tipped hole saws are typically selected for tougher mixed-material cuts, while bi-metal saws are often used for more routine wood and light metal work. Actual performance depends on drill speed, pressure, material thickness and pilot setup.
