Starrett 40268 Bi-metal Power Hacksaw Blade 10 Tpi

Product Description

The STARRETT 40268 is a bi-metal power hacksaw blade built for machine-driven cutting operations in metalworking and fabrication environments. It measures 18 inches in length, 1.375 inches wide, and 0.062 inches thick, with a 10 TPI constant pitch tooth pattern and a toothed edge configuration. The bi-metal construction bonds a high-speed steel tooth edge to a flexible alloy steel backing, giving the blade resistance to tooth breakage under the repeated stress of power hacksaw cycling. Licensed machinists, fabricators, and maintenance technicians are the primary installers and users of this blade type.

This blade is designed for use in reciprocating power hacksaw machines in industrial, maintenance, and job-shop settings. The 10 TPI constant pitch pattern suits solid bar stock, structural steel, and similar ferrous materials in moderate cross-sections. The 0.281-inch pinhole diameter is sized for standard power hacksaw blade pin-mount tensioning systems. It is sold and packaged individually, making it a practical single-replacement option for scheduled blade changes or mid-job failures.

Key Features

• Bi-metal construction with high-speed steel teeth bonded to a flexible alloy steel back
• 10 TPI constant pitch pattern for consistent chip load on solid and structural metals
• 18-inch blade length fits standard power hacksaw frames
• 1.375-inch blade width and 0.062-inch thickness for rigid tracking under power stroke loads
• 0.281-inch pinhole diameter for pin-mount tensioning compatibility
• Toothed edge configuration for directional cutting on power hacksaw machines

Compatibility

Designed as an OEM-style replacement blade for power hacksaw machines that accept 18-inch pin-mount bi-metal blades with a 0.281-inch pinhole diameter.

Installation Notes

Power hacksaw blade replacement should be performed by a qualified machinist or maintenance technician with the machine fully de-energized and locked out per OSHA lockout/tagout procedures before starting. Verify blade tension according to the machine manufacturer's specification after seating the blade pins. Ensure blade tracking is aligned with the guide arms before test-cycling the machine at low speed. Handle bi-metal blades with cut-resistant gloves, as tooth edges remain sharp even on worn blades.
