Lenox 39643CLB113505 Bandsaw Blade 138in 4-6 Tpi Bi-metal

Product Description

The LENOX 39643CLB113505 is a welded bi-metal bandsaw blade designed for continuous cutting of metals in stationary bandsaw machines. At 138 inches (11 feet 6 inches) long and 0.75 inches wide, it fits standard horizontal and vertical band saws in that size range. The blade runs a variable pitch of 4 to 6 TPI with a Vari-Raker tooth set, which reduces vibration and harmonic chatter during cuts. The cutting teeth are M42 high speed steel, a cobalt-bearing grade that holds an edge longer when cutting tough alloys and hardened materials. Back material is spring steel for fatigue resistance under continuous flex. Blade thickness is 0.035 inches with a kerf of 0.058 inches.

This blade is suited for professional metalworking shops, fabrication facilities, and maintenance operations cutting a wide range of ferrous and non-ferrous stock. It handles alloy steel, carbon steel, stainless steel, structural steel, tool steel, aluminum, and non-ferrous metals. The variable pitch design makes it effective on interrupted cuts and varying cross-sections, such as tubing, structural shapes, and solid bar stock. It is part of the LENOX Classic series, intended for general-purpose production cutting where consistent performance across material types is required. Installed by machinists, tool room technicians, and fabricators.

Key Features

• M42 high speed steel teeth with cobalt content for extended edge life on tough alloys
• Variable 4 to 6 TPI pitch with Vari-Raker tooth set reduces vibration and chatter
• Bi-metal construction: M42 tooth edge bonded to spring steel back for flex fatigue resistance
• 0.058-inch kerf width minimizes material loss per cut
• Welded blade loop, 138 inches long, ready to install without field joining
• Cuts alloy steel, carbon steel, stainless steel, tool steel, aluminum, and non-ferrous metals

Compatibility

Designed to fit stationary bandsaws with a 138-inch (11 feet 6 inches) blade capacity and a 0.75-inch blade width specification. Verify wheel diameter, blade guide clearance, and wheel width on the machine before installation.

Installation Notes

Bandsaw blade replacement should be performed with the machine fully de-energized and the power source locked out per OSHA lockout/tagout procedures. Wear cut-resistant gloves when handling the coiled or uncoiled blade. Set blade tension and tracking according to the bandsaw manufacturer's specifications before running the machine. Inspect blade guides, guide bearings, and wheel tires for wear before installing a new blade.
