Lenox 12647GTBQM Welded Bandsaw Blade 3 to 4 Tpi Bi-metal

Product Description

The LENOX 12647GTBQM is a welded bi-metal bandsaw blade designed for continuous loop cutting on horizontal and vertical bandsaw machines. It measures 186 inches (15 feet 6 inches) in length, 1-1/2 inches in width, and 0.05 inches in thickness. The blade runs a variable-pitch tooth pattern at 3 to 4 TPI, which helps reduce harmonic vibration and produces cleaner cuts across a range of cross-sections. High speed steel teeth are electron-beam welded to a flexible alloy steel backer, giving the blade resistance to tooth strippage under intermittent load. Metal fabricators, pipefitters, and maintenance machinists are the primary installers of this blade type.

This blade is suited for structural steel cutting, pipe and tube cutting, and general metal fabrication in shop environments. The variable 3 to 4 TPI pitch makes it well-matched for medium to heavy cross-section ferrous and non-ferrous stock where a coarser pitch is needed to clear chips effectively. The positive rake angle on the teeth promotes aggressive feed rates and reduces cutting time on solid bar stock and thick-walled tubing. It is intended for professional shop use where blade length and tooth geometry are matched to the machine and material specification.

Key Features

• Bi-metal construction with high speed steel teeth bonded to a flexible alloy backer for extended tooth life
• Variable pitch at 3 to 4 TPI reduces vibration and chatter during cutting
• Positive tooth rake angle supports aggressive feed rates on solid and structural stock
• 186-inch welded loop length fits standard horizontal and vertical bandsaw frames requiring 15-foot 6-inch blades
• 1-1/2-inch blade width provides lateral stability during contour and straight cuts
• 0.05-inch blade thickness minimizes kerf width and reduces material waste

Compatibility

Designed as a replacement bandsaw blade for horizontal and vertical metal-cutting bandsaw machines requiring a 186-inch (15 feet 6 inches) loop length and a 1-1/2-inch wide blade track.

Installation Notes

Blade installation should be performed by a qualified machinist or maintenance technician following the bandsaw manufacturer's tensioning and tracking procedures. Power down and lockout/tagout the bandsaw before removing the old blade or installing the new one. Verify wheel diameter, blade guide spacing, and blade tension specification on the machine nameplate before mounting. Always wear cut-resistant gloves when handling uncoiled or looped bandsaw blades.
