Mk Morse 4851040934 M42 Bi-metal Band Saw Blade 4 Tpi

Product Description

The MK MORSE 4851040934 is an M42 bi-metal band saw blade built for continuous cutting in demanding shop and production environments. At 93.5 inches in length and 0.025 inches thick, this blade runs at 4 teeth per inch (TPI), making it well-suited for cutting larger cross-sections of metal, structural steel, and hard alloys. The M42 designation indicates an 8-percent cobalt high-speed steel tooth tip bonded to a flexible alloy steel backer, a construction that extends tooth life at higher feed rates and cutting speeds compared to standard carbon blades. HVAC fabricators, pipefitters, maintenance machinists, and metal fabricators typically rely on this blade type for high-cycle applications.

This blade is designed for use on horizontal and vertical band saws that accept a 93.5-inch blade loop. The 4 TPI tooth pitch is best matched to solid bar stock, large-diameter tubing, structural shapes, and bundle cutting of similar profiles. It performs well on stainless steel, tool steel, titanium, and other difficult-to-machine alloys where heat buildup and tooth wear are primary concerns. The reduced-vibration geometry helps maintain consistent cut quality over extended production runs.

Key Features

• M42 bi-metal construction: cobalt HSS teeth bonded to a flexible alloy steel backer for extended blade life
• 93.5-inch blade length fits a wide range of horizontal and vertical production band saws
• 4 TPI tooth pitch optimized for large cross-sections, solid bar, and structural profiles
• 0.025-inch blade thickness provides a balance of rigidity and flex for straight tracking
• Engineered to reduce vibration and harmonics during high-feed cutting passes

Compatibility

Designed as an OEM-style replacement band saw blade for horizontal and vertical band saws accepting a 93.5-inch blade loop length.

Installation Notes

Band saw blade installation should be performed by a qualified machinist or maintenance technician. Power down and lock out the saw before removing the old blade or installing the new one. Verify blade tension, tracking alignment, and guide bearing clearance after installation before resuming cutting. Wear cut-resistant gloves when handling coiled band saw blades, as the coil can release unexpectedly.
