Band saws are not suitable for cutting very thin sheet metal; a rule of thumb suggests the metal to be cut should be thicker than the depth of 3 band saw blade teeth, however they are excellent for cutting thin walled profiles such as box and angle. Blades with a higher tpi provide a smoother cut edge whereas blades with a lower tpi make light work of cutting through thicker metal stock. For cuts using a cordless band saw; ensure the workpiece is secure, line up the blade to the intended cut line and lower the blade into the metal.
I’ve wondered about this, too-I think I remember the guys at Sears telling me the metal saws go 23 or 33 percent slower…I don’t exactly remember the numbers. Sears does sell a two-speed bandsaw for wood and metal. Knowing the FPS of the saw currently would also be a good number to know.
Too often, a homeowner or hobbiest tries to cut metal with the wood cutting bandsaw they have. The saw is mainly used for wood but on occasion I cut metal. As you can see above, the reason for his inablility to cut stainless had nothing to do with the blade, but everything to do with the saw.
The constant turning of the band forms a formidable cutting action of the band as the material being cut is moved through the blade. It’s a fine addition to any woodworking shop and versatile enough to cut not only wood but also metal and other materials. Generally speaking, blades intended for cutting wood will have larger teeth and a low TPI. The teeth will angle down, cutting down through the wood rather than angled up that can lift the wood as it is being cut.
Even an old band saw that has been properly operated and maintained can achieve a high-quality cut approaching that of a modern band saw. Your saw blade vendor can supply charts for materials, blade speeds, and cutting rates and has access to the blade manufacturer’s technical department for answers to specific questions. In most cases, crooked cuts can be traced back to improper saw operation such as too much downfeed pressure, too slow a blade speed, or the guide arms are too far away.
how to use a bandsaw to cut metal Related Question:
Can I use my band saw to cut metal?
Band saws are not suitable for cutting very thin sheet metal; a rule of thumb suggests the metal to be cut should be thicker than the depth of 3 band saw blade teeth, however they are excellent for cutting thin walled profiles such as box and angle.
Can I put a metal cutting blade on my band saw?
Salem Straub. Typically if you run a metal blade on a wood bandsaw the excessive speed (2000 sfpm+) of the wood saw will knock the teeth off of your metal cutting blade in a hurry. You could make it work, but you would have to slow the blade drive wheel way down. Think 250 sfpm to 80 sfpm.
What is the difference between a wood band saw and a metal band saw?
A metal cutting bandsaw is typically built more solidly than a saw designed for cutting wood, so there are no issues with the machine itself. As for the blade, the wood fibers could clog the metal blade’s teeth more quickly, and the blade will probably cut through the wood more slowly.
Can a band saw cut stainless steel?
Bi-metal band saw blades cover the broadest range of sawing applications. 95% of companies and individuals cutting the following materials should use a bi-metal band saw blade: carbon steel, tool steel, structural steel, stainless steel, pipes/tubing, die steel, angles, flat stock and mixed metal applications.
What speed should you cut metal with on a bandsaw?
To cut steel, you’ll need to run the machine at a much slower speed — about a hundred feet per minute. A machine running at this speed might look like it’s running too slowly, but running it any faster almost guarantees that you’ll damage the blade.
Can you use a band saw to cut aluminum?
Band saws generally make sense for aluminum stock of 6 in. diameter and larger and for shops that are interested in high-speed cutting of aluminum but also frequently cut other materials.
How long should a metal bandsaw blade last?
On average your bandsaw blade should last 6 months to as long as a few years depending on what your cutting with it. Make sure to match your blade strength and quality to the project and material your cutting.
Can you cut metal with a wood blade?
While a metal-cutting saw has a collection bin to prevent metal chips from getting into the machine, a woodcutting saw isn’t designed this way. If you do decide to use a wood saw on metal, only use a 7 1/4-inch blade and preferably a worm drive blade, which provides extra torque.
Can you use a band saw to cut wood?
With the correct blade, a band saw can cut wood or metal, in either curves or straight lines. Blades come in a variety of widths and tooth counts. Narrower blades are good for tighter curves, while wider blades are better at straight cuts.
What is the best TPI for cutting metal?
Cutting thinner metals, including sheet metal, requires a finer cut. Use 18-24 TPI bi-metal blades. For thicker metals such as steel pipe, angle irons, or tubing, use 14-18 TPI bi-metal blades. For aluminum, an 8-10 TPI blade is best.
What materials can a bandsaw cut?
Most bandsaws have two wheels rotating in the same plane, one of which is powered. The blade itself can come in a variety of sizes and tooth pitch (teeth per inch, or TPI) which enables the machine to be highly versatile and able to cut a wide variety of materials including wood, metal and plastic.
What is a bimetal bandsaw blade?
Bi-Metal bandsaw blades feature an oversized blade width to increase beam strength, an M-42 high-speed steel tooth hardened to 69Rc to improve wear resistance, and a variable tooth pitch. A very popular tooth form, the variable pitch reduces cutting vibration while increasing the speed of the cut.
Can bimetal cut stainless steel?
A good bi-metal hole saw will easily cut through softer materials, such as plastic and wood-based items, as well as harder materials, such as steel and stainless steel. The type of high speed steel chosen by the hole saw manufacturer will contribute greatly to the performance of the hole saw.
How much tension should a bandsaw blade be?
For carbon steel toothed blades (cutting blades) this is typically 15,000 to 25,000 PSI. Slitting type blades typically are tensioned in the range of 12,000 to 20,000 PSI. In general bandsaw blades are never tensioned past 35,000 psi.
How high can a bandsaw cut?
The resaw capacity is the maximum height (thickness) that can be cut. For the small shop furniture maker, go with 14″ as the minimum for a bandsaw, though 16″ is better. Those doing larger work might even want 18″ or 20″ machines. Just make sure you have a minimum resaw height of 12″ for versatility.
