Lenox 81939D2B72375 Welded Bandsaw Blade 14-18 Tpi

Product Description

The LENOX 81939D2B72375 is a welded bi-metal bandsaw blade designed for precision contour cutting across a wide range of metals and materials. Measuring 93.5 inches long and 0.5 inches wide with a blade thickness of 0.025 inches, it runs on horizontal and vertical band saws used in metal fabrication and general trade shops. The variable pitch tooth form spans 14 to 18 TPI, reducing vibration and harmonic chatter during cuts. The M42 high speed steel tooth material provides edge retention on hard materials. Spring steel backing adds flexibility and fatigue resistance during continuous operation. Installed by machinists, fabricators, and maintenance trades.

This blade is suited for cutting alloy steel, carbon steel, stainless steel, structural steel, tool steel, aluminum, non-ferrous metals, and wood. The wavy tooth set and variable pitch pattern make it effective for thin-wall tubing, solid bar stock, and structural profiles where consistent chip clearance matters. The toothed, milled cutting edge style supports smooth entry and exit cuts. It fits band saws that accept a 93.5 inch blade length in the 0.5 inch width class, making it a practical choice for shop floor and jobsite cutting operations.

Key Features

• Bi-metal construction with M42 high speed steel teeth bonded to a spring steel back for durability and flex resistance
• Variable pitch 14 to 18 TPI reduces vibration and suits a wide range of cross-sections and material thicknesses
• Wavy tooth set promotes efficient chip evacuation and reduces blade binding
• Contour cutting capability allows curved and irregular profile cuts
• Compatible material applications include stainless steel, tool steel, aluminum, non-ferrous metals, carbon steel, structural steel, and wood
• Kerf width of 0.043 inches supports tight tolerances and minimal material loss

Compatibility

Designed as an OEM-style replacement welded bandsaw blade for band saws accepting a 93.5 inch blade length in the 0.5 inch width class. Verify blade length, width, and thickness against your saw specifications before installation.

Installation Notes

Bandsaw blade installation and tensioning should be performed by a qualified machinist or maintenance technician with the saw fully powered down and locked out per OSHA lockout/tagout procedures. Confirm wheel diameter, blade guides, and tensioner range are compatible with the blade dimensions before mounting. Do not exceed the blade manufacturer's recommended feed rate or wheel speed for the material being cut. Inspect blade welds and tooth condition before each use and replace at the first sign of cracking or missing teeth.
