Blade HACKSAW BI-METAL HI-CUT 300 x 13-32T

A hacksaw is a fine-tooth hand saw with a blade held under tension in a frame, used for cutting materials such as metal or plastics. Hand-held hacksaws consist of a metal arch with a handle, usually a pistol grip or dee grip, with pins for attaching a narrow disposable blade. A screw or other mechanism is used to put the thin blade under tension. The blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke. On the push stroke, the arch will flex slightly, decreasing the tension on the blade, often resulting in an increased tendency of the blade to buckle and crack. Cutting on the pull stroke increases the blade tension and will result in greater control of the cut and longer blade life.

• For heavy-duty cutting jobs like steel reinforcing rod or pipe, an 18-teeth per inch blade would be the best choice
• For a job that requires medium-duty cutting, like a thin wall electrical conduit, a 24-teeth per inch blade would do a better job
• When cutting light metals like aluminum, a 32-teeth per inch blade should easily do the trick

• Length: 300 mm ( Hacksaw blades have two holes near the ends for mounting them in the saw frame and the 12 inch / 300 mm dimension refers to the center to center distance between these mounting holes )
• Hole to Hole: 11 7/8 inches / 300 mm
• Overall blade length: Approx 315 mm
• Mounting Hole diameter: 3.5 to 4 mm
• Blade Width: 11 to 13 mm
• Blade Thickness: 0.020 to 0.027 inches / 0.5 to 0.70 mm (varies with tooth pitch and other factors)


Should hacksaw teeth face forward or backward?

Install the hacksaw blade so the teeth face forward. The saws are designed so the blade will cut when it's pushed (the forward stroke) rather than when pulled (see photo). Some blades have an arrow that shows the correct installation (the arrow points toward the handle). Install the blade so it's tight in the saw and won't bend. When you do a lot of cutting, the blade will heat up and expand, so be sure to tighten it if it starts to bend.

The blade can be replaced by loosening the wing nut adjuster until it comes off the two ???studs??? that normally hold it in tension in the frame.
