Value Collection CT7-1-1/2 Carbide Tipped Hole Saw

Product Description

The VALUE COLLECTION CT7-1-1/2 is a carbide tipped hole saw designed for cutting clean, accurate holes in a wide range of materials common to HVAC, plumbing, and electrical rough-in work. The saw measures 1-1/2 inches in diameter with a 1-inch cutting depth, making it well suited for single-pass cuts through sheet metal, pipe flanges, electrical enclosures, and structural panels. The carbide tipped teeth extend tool life significantly compared to standard bi-metal saws when working in abrasive or hard materials. The 3/8-inch shank diameter fits standard drill chucks and arbors used in the trades.

This hole saw is rated for use in aluminum, cast iron, copper, fiberglass, iron, stainless steel, and mild steel. It is a practical choice for HVAC installers cutting sheet metal for duct penetrations, plumbers boring through copper or cast iron, and electricians cutting knockouts in enclosures and panels. The 1-1/2-inch diameter is a common size for conduit, small supply stubs, and sensor port openings in residential and light commercial installations.

Installation Notes

A licensed HVAC technician, plumber, or electrician typically selects hole saws based on the material and wall thickness being penetrated. Use appropriate cutting fluid or lubricant when boring through stainless steel or cast iron to extend blade life and reduce heat buildup. Ensure the workpiece is secured before cutting, and verify that no live conductors, pressurized lines, or structural members are present behind the cut zone. Always wear eye protection and appropriate PPE when operating rotary cutting tools.
