Reed 04491 Bi-metal Hack Saw Blade 12 Inch 18 Tpi

Product Description

The REED 04491 is a bi-metal hack saw blade built for demanding trade cutting applications. The cutting edge is high-speed steel, electron-beam welded to an alloy steel back for durability and resistance to blade breakage under load. A wavy-set tooth profile reduces binding and improves chip clearance in metal and conduit cuts. At 12 inches long, 0.5 inches wide, and rated at 18 teeth per inch (TPI), this blade is suited for general-purpose ferrous and non-ferrous metal cutting where a fine, controlled cut is required. Licensed tradespeople in plumbing, HVAC, and electrical work reach for this blade when cutting pipe, strut, and threaded rod.

This blade is appropriate for residential and commercial jobsite use wherever a standard hack saw is part of the workflow. It is well-suited for cutting copper, steel, and galvanized pipe, electrical conduit, all-thread rod, and similar materials encountered in mechanical, plumbing, and electrical rough-in work. Performance is optimized when the blade is mounted in a high-tension hack saw frame, which reduces blade flex and extends cutting life.

Key Features

• High-speed steel cutting edge electron-beam welded to alloy steel back for strength and long service life
• Wavy-set tooth geometry minimizes binding and improves chip evacuation
• 18 TPI tooth count suited for medium-wall and thin-wall metal cutting
• 12-inch blade length fits standard full-size hack saw frames
• Optimized for use in high-tension frames for best cutting performance and blade safety

Compatibility

Designed as a standard-length replacement blade for full-size hack saw frames accepting 12-inch bi-metal blades.

Installation Notes

Blade installation and replacement should be performed by the technician or tradesperson on the job. Secure the blade in the frame with the teeth pointing forward, away from the handle, and tension the blade firmly before cutting. High-tension frames are recommended to minimize blade flex and reduce the risk of breakage during use. Inspect the blade for cracks or missing teeth before each use and replace if damaged.
