Lenox 89431QPB154725 Bandsaw Blade 186in 2-3 Tpi Bi-metal

Product Description

The LENOX 89431QPB154725 is a welded bi-metal bandsaw blade engineered for demanding metal-cutting applications in industrial and fabrication environments. The blade measures 186 inches in length and 1-1/2 inches in width, with a 0.05-inch body thickness and a variable-pitch tooth pattern rated at 2 to 3 TPI. The bi-metal construction pairs a spring steel back with M42+ high speed steel teeth, delivering the flexibility to resist blade fatigue while maintaining edge hardness through repeated cuts. Licensed HVAC, plumbing, and mechanical contractors as well as fabrication shop personnel install and service blades of this type.

This blade is designed for vertical or horizontal band saws that accept 186-inch loop blades at 1-1/2-inch width. The 2 to 3 TPI variable pitch is suited for cutting a broad range of cross-sections and materials including alloy steel, carbon steel, stainless steel, tool steel, mold steel, bearing steel, aluminum, other non-ferrous metals, and titanium. The QXP series designation indicates a ground, variable tooth form with a positive rake angle and single-level set, characteristics that support consistent chip clearance and reduced vibration during cuts through varying wall thicknesses or irregular profiles. This blade is intended for contour-free straight cutting operations.

Key Features

• Bi-metal construction: spring steel back bonded with M42+ high speed steel teeth for durability and flexibility
• Variable pitch 2 to 3 TPI reduces harmonic vibration and suits varied cross-sections
• Positive rake angle and ground tooth form support aggressive, clean cuts through ferrous and non-ferrous metals
• Single-level tooth set with 0.082-inch kerf width for controlled material removal
• QXP series blade — factory welded to 186-inch loop, ready to install without field welding
• Rated for alloy steel, stainless steel, titanium, aluminum, and additional ferrous and non-ferrous materials

Compatibility

Designed as an OEM-style replacement or direct-fit blade for band saws accepting a 186-inch blade loop at 1-1/2-inch width. Verify wheel diameter, blade guide clearance, and tension specifications on the host saw before installation.

Installation Notes

Blade installation should be performed by qualified personnel familiar with band saw equipment. Disconnect and lock out electrical power to the saw before removing the old blade or mounting a new one. Confirm proper blade tension according to the saw manufacturer specifications and ensure blade guides and thrust bearings are adjusted to suit the 1-1/2-inch blade width before powering up. Wear cut-resistant gloves when handling the blade loop.
