Starrett 40068 Power Hacksaw Blade 18in 6 Tpi Hss

Product Description

The STARRETT 40068 is an 18-inch high speed steel power hacksaw blade rated at 6 teeth per inch (TPI), designed for use in reciprocating power hacksaw machines found in metal fabrication shops and industrial maintenance environments. The blade measures 1.5 inches wide and 0.075 inches thick with a constant pitch tooth pattern and a toothed edge configuration. High speed steel construction provides the hardness and heat resistance needed to cut ferrous metals, structural steel, and similar materials under continuous power-driven operation. This blade is a consumable component installed by machinists, tool and die tradespeople, and industrial maintenance technicians.

The 40068 is suited for production cutting applications on stationary power hacksaw machines. The constant pitch pattern at 6 TPI makes it appropriate for cutting solid bar stock, thick-walled tubing, and structural sections where a coarser tooth count supports efficient chip clearance and reduces blade loading. The 0.4130-inch pinhole diameter fits the standard drive pin configuration common on industrial power hacksaw frames.

Key Features

• 18-inch blade length for standard power hacksaw frame sizes
• 6 TPI constant pitch pattern optimized for thick cross-sections and solid stock
• High speed steel construction for hardness and heat resistance during power-driven cutting
• 1.5-inch blade width provides rigidity and straight-tracking cuts
• 0.075-inch thickness sized for typical power hacksaw blade guides
• 0.4130-inch pinhole diameter for standard drive pin fitment

Compatibility

Designed as an OEM-style replacement blade for stationary power hacksaw machines that accept 18-inch blades with a 0.4130-inch pinhole diameter and a 1.5-inch blade width.

Installation Notes

Power hacksaw blades should be installed by qualified maintenance or machine shop personnel. Power off and de-energize the machine before removing the worn blade or installing a replacement. Verify blade tension is set according to the machine manufacturer's specification before resuming cutting operations. Inspect blade guides and pinhole seat for wear each time a blade is replaced.
