Starrett 00453 Hole Saw 3 in Hss Variable Pitch

Product Description

The STARRETT 00453 is a high speed steel (HSS) hole saw designed for cutting through metal, steel, and wood in demanding trade applications. With a 3-inch saw diameter and a 2-inch cutting depth, this saw handles a wide range of rough-in and service work where a clean, full-depth hole is required. The toothed cutting edge runs a variable pitch pattern of 4 to 6 teeth per inch, which reduces vibration and helps clear chips efficiently during the cut. It is used by HVAC technicians, plumbers, electricians, and general contractors who need reliable hole saws for panel knockouts, pipe penetrations, and conduit routing.

This hole saw is suited for both residential and light commercial applications. The variable pitch tooth pattern makes it effective on metal sheet goods, structural steel, and wood framing or sheathing. It is a practical choice when a single saw needs to handle mixed-material cuts on a job site without swapping tools. The 3-inch diameter is a common size for pipe sleeve openings, electrical junction work, and HVAC duct collar penetrations.

Key Features

Compatibility

Designed as an OEM-style replacement hole saw compatible with standard arbors accepting 3-inch hole saw bodies across residential and commercial trade applications.

Installation Notes

Installation is performed by HVAC technicians, plumbers, and electricians using a compatible hole saw arbor and a corded or cordless drill or drill press. Secure the workpiece before cutting and use appropriate cutting fluid when working through steel to extend blade life. Always wear eye protection and ensure the work area is clear of energized conductors or pressurized lines before cutting. Follow applicable NEC, IPC, or IFGC clearance requirements when making penetrations through structural or fire-rated assemblies.
