Starrett 40076 Power Hacksaw Blade 21 in 6 Tpi Hss

Product Description

The STARRETT 40076 is a high speed steel power hacksaw blade designed for use in reciprocating power hacksaw machines. Measuring 21 inches in length, 1-3/4 inches wide, and 0.088 inches thick, this blade delivers consistent cutting performance on metal stock. The 6 TPI constant pitch tooth pattern is suited for cutting thicker-walled material and solid stock where a coarser pitch improves chip clearance and reduces heat buildup. High speed steel construction maintains edge hardness under the elevated temperatures generated during power hacksaw operation. This blade is installed and serviced by machinists, maintenance technicians, and metalworking professionals.

This blade is intended for use in stationary power hacksaw machines commonly found in machine shops, fabrication facilities, and industrial maintenance environments. The 21-inch length and 1-3/4-inch width fit standard power hacksaw frames that accept blades in this size range. The 6 TPI pitch makes it well suited for cutting solid bar stock, structural shapes, and thick-walled tubing in ferrous and non-ferrous metals. The 0.2810-inch pinhole diameter is sized to fit standard blade-tensioning pins on compatible machines.

Key Features

Compatibility

Designed as a replacement blade for stationary power hacksaw machines that accept 21-inch blades with a 1-3/4-inch width and 0.2810-inch pinhole diameter.

Installation Notes

Power hacksaw blades are installed and replaced by machinists or maintenance technicians. Before replacing a blade, power down the machine and allow all moving parts to come to a full stop. Ensure proper blade tension is set according to the machine manufacturer specifications after installation. Teeth should be oriented in the correct cutting direction for the machine stroke before securing the blade in the frame.
