A hacksaw is used to cut metals. The blades are easily changeable and come in many tooth sizes. Very hard metals like tool steel need many small teeth, so here you would fit a very hard 32 or 36 tpi blade (teeth per inch). Softer metals can be cut with cheaper blades with teeth of about 12 -16 per inch.
For cutting 1 2-inch EMT conduit, a hacksaw blade with 14 to 18 teeth per inch (TPI) is generally recommended. This range provides a balance between cutting speed and the smoothness of the cut, allowing for effective slicing through the metal without excessive effort. Using a blade within this TPI range ensures a clean cut while minimizing the risk of damaging the conduit.
The number of teeth on a hacksaw blade is determined by the material being cut and the thickness of that material. Generally, a blade with more teeth per inch (TPI) is suitable for cutting thinner materials or metals, providing a smoother finish. Conversely, blades with fewer teeth are better for thicker materials, allowing for faster cuts. As a rule of thumb, it's recommended to have at least three teeth in contact with the material at all times for efficient cutting.
A good quality jigsaw will cut almost any material with the correct blade. Although I have 3 jigsaws my favourite is the Bosch1578AVS that I've had over 30 years. I still use it 3-4 times a week to cut wood of different kinds, plexiglass and steel. The steel cutting blade is like a very fine hacksaw blade with 24 teeth per inch. An average wood cutting blade will have about 8 teeth per inch.
The pitch of a hacksaw blade refers to the distance between the teeth on the blade, typically measured in teeth per inch (TPI). Common pitches for hacksaw blades range from 14 TPI for cutting metal to 32 TPI for cutting thinner materials or plastics. A finer pitch (higher TPI) is used for smoother cuts, while a coarser pitch (lower TPI) is better for quicker, rough cuts. Choosing the right pitch is essential for achieving optimal cutting performance based on the material being cut.
With a hacksaw, a power saw with an abrasive blade or a pair of bolt cutters. Hacksaw is probably the easiest, cheapest way.
That's a typical hacksaw count, suitable for cutting metals and hard plastics. It will also cut wood, but rather slowly and not in big pieces.
