Lenox 1803189 Welded Bandsaw Blade 3-4 Tpi Bi-metal M42

Product Description

The LENOX 1803189 is a welded bi-metal bandsaw blade designed for continuous cutting in metalworking applications. It measures 104.5 inches long, 1 inch wide, and 0.035 inches thick, with a variable 3 to 4 TPI tooth pitch suited for cutting a range of material thicknesses and profiles. The blade features an M42 high-speed steel tooth edge bonded to a spring steel back, a combination that delivers both edge retention and flex resistance during operation. The Vari-Raker tooth set and variable pitch pattern work together to reduce vibration and harmonic noise during the cut. This blade is installed by metalworking professionals and fabrication shop technicians on vertical and horizontal band saws.

This blade is suited for production and job-shop environments where a wide variety of metals must be cut on a single machine setup. Compatible material applications include alloy steel, carbon steel, stainless steel, structural steel, tool steel, mold steel, bearing steel, aluminum, and other non-ferrous metals. The variable tooth form supports both solid bar stock and structural sections without requiring a blade change between material types. It is part of the LENOX Classic Pro series, targeting professional-grade band saw operations that demand consistent performance across high-volume cutting cycles.

Key Features

• M42 high-speed steel teeth bonded to a spring steel back for durability and flex resistance
• Variable 3 to 4 TPI pitch reduces vibration and improves cut quality across material thicknesses
• Vari-Raker tooth set with positive rake angle for aggressive, efficient chip clearance
• 0.057 inches kerf width minimizes material loss per cut
• Toothed, milled, and variable cutting edge style for versatility across metal types
• Rated for alloy steel, stainless steel, carbon steel, aluminum, tool steel, and more

Compatibility

Designed as an OEM-style replacement or direct-fit welded blade for vertical and horizontal band saws accepting a 104.5-inch blade length with a 1-inch blade width. Confirmed material applications include alloy steel, aluminum, non-ferrous metals, carbon steel, stainless steel, structural steel, tool steel, mold steel, and bearing steel.

Installation Notes

Band saw blade installation should be performed by a qualified metalworking technician with the machine fully powered down and locked out per OSHA lockout/tagout procedures. Verify wheel diameter and blade tracking adjustment before tensioning the new blade to the saw manufacturer's specification. Blade guides and thrust bearings should be inspected and reset to the correct clearance for a 1-inch wide blade before resuming operation. Always confirm blade travel direction matches the tooth orientation before powering the machine on.
