Hacksaw Tips

Use a hacksaw to cut long strokes through a material's surface.

Hacksaws have thin blades, pulled taut by the end post and handle post they are attached to. The bridge connecting the two posts restricts how far the hacksaw blade can saw through a material -- about 3 inches or less. Hacksaws are used to cut through metal and plastic, though are sometimes also used for wood. Following these tips will make the sawing process easier.

Position the PIpe/Material Properly In A Vise

Hacksaws cause vibration when the blade is moved backwards and forwards across the cutting surface. Secure the pipe/material in a vise, with the cutting line within 3 inches of the vise jaws. Doing so will decrease vibrations, making it easier to cut in a straight line, as well as starting the cutting grove on the material's surface.

Cut In Long Strokes

Position a thumb against one side of the saw blade while beginning to establish the cutting groove. This will help keep the blade upright and perpendicular to the material's surface. Push the blade fully backwards and forwards across the cutting surface to help create the groove. Short cuts make the blade's teeth bounce out of the groove, marking the surface around the cut and possibly causing bodily harm.

Apply Oil

When the blade has formed the initial groove and is deeper inside the material, its thinness may cause the blade to stick, causing jerking actions which prevent a straight cut and possibly breaking the blade. Rub some lubricating oil onto each side of the blade, to create less friction between the blade and cutting surface. Wipe off the oil from the blade and cut after sawing.

Change The Blade's Angle

Loosen the wing nuts on the ends of the hacksaw's handle and end post that hold the blade in place and move the blade to any angle up to 90 degrees to the hacksaw's frame. This will help cut previously installed surfaces that are difficult to reach.
