You must select the correct Teeth Per Inch for the thickness of material you are cutting. That’s why Dakin-Flathers have created this useful bandsaw teeth per inch chart. Use the bandsaw teeth per inch chart below to select the optimum TPI for your project needs.

The biggest factor in blade life on a portable is quality, I’ve tried every blade manufacturer out there over the years. “One other tid bit. I make my own saw backstop for placing up against the work. The one that came on my saw was flimsy bent sheet metal and only supported stock on one side of the cut. I use a piece of 1/4 x 1 1/2” band iron with a kerf for the blade and a little longer than the stock unit.
If the sheet metal is too thin for this to work with the finest tooth blade available, a useful trick is to put the metal between pieces of plywood, fiberboard, or soft thicker metal to support the blade. Our webpage How to use a BandSaw has a guide for selecting the proper pitch band saw blade for different metals and metal thickness. Recommended use of a CARBON STEEL BLADE Thickness of metal to be cut Blade Teeth per inch For high speed cutting of aluminum, brass, copper, soft bronze, magnesium, wood, mild steel and also tougher steels at slow speed.
Basically, should you cut a lot of thin material, a high TPI number is appropriate. Like 0.063 thin material, 32 TPI or higher should be used. I can suggest a 601 Haltbar bi metal 14 TPI bandsaw blade for your material.
The ideal TPI for cutting thick aluminum plate is 10-14. Thickness of metal to be cut Blade Teeth per inch 1/8″ to 1/2 inch thick 18 3/32″ to 1/8 inch thick 24 Thickness of metal to be cut Blade Teeth per inch 7/32″ to 7/8 inch thick 3/16″ to 5/8 inch thick 5/32″ to 3/8 inch thick 10 14 18. Cutting thinner metals, including sheet metal, requires a finer cut.
what tpi bandsaw blade for metal Related Question:
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.
Is more TPI better for cutting metal?
Blades with higher TPI remove smaller amounts of material with each pass. Therefore they cut slower and leave a much smoother edge. Blades 12-18 TPI are typically used for metal and denser materials as well as finish cuts in wood. The 18-24 TPI range is almost always used for metal cutting.
What is the best TPI for bandsaw blades?
Use coarse tooth blades (2 or 3 TPI) for re-sawing and cutting thicker materials. For general wood cutting duties in typical 3/4″ material, use a 4 TPI blade for coarse, fast cutting and a 14 TPI blade for slower, smoother cutting. A blade in the 6 to 8 TPI range provides good general-purpose performance.
What kind of blade do you use to cut metal?
Ferrous blades are ideal for cutting metals that contain iron, such as stainless steel or cast iron. Choose a non-ferrous blade when cutting softer metals, like aluminum or copper. For the best results, use a diamond blade that’s rated to cut the type of metal you are working with.
What is the best blade for cutting metal?
We recommend using a diamond blade that’s labeled as a ferrous-metal-cutting blade, but many tradespeople use a regular masonry diamond blade with good results.
What is 14 TPI for cutting?
8-14 TPI blades are capable of cutting wood and the occasional nail. Demo blades fall into this category. 14-24 TPI is the range of metal cutting, PVC cutting and finish cut blades. The blades cut slowly, but leave being a very smooth edge.
How do you measure a TPI on a bandsaw blade?
To avoid stripping teeth, always have a minimum of three teeth in the work surface How to measure TPI: Measure 1 or 2 inches along the blade from the center of the gullet. Count the number of teeth in that space. This is the TPI.
What does DPI mean on a bandsaw blade?
Home / Blog / Hints & Tips / Band Saw Blade Teeth Per Inch (TPI) Chart. You must select the correct Teeth Per Inch (TPI) for the thickness of material you are cutting.
Is more TPI better?
Woodworkers quickly learn that the number of teeth-per-inch (TPI) on the blade has a big impact on the quality of a cut. The general rule of thumb is “the more TPI, the smoother the cut.” The true answer, however, is just a little more complicated than that, as you’ll learn once you understand how saw teeth work.
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.
How thick of metal can a band saw cut?
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.
What is resawing on a bandsaw?
Bandsaw Resawing from the beginning: resawing is cutting a sawn plank of wood into thinner planks on a bandsaw. Thus the cut runs through the plank’s width, which distinguishes bandsaw resawing from ordinary bandsaw rip cuts where the blade runs through the stock’s thickness.
Why do some power hacksaws need a coolant system?
Power Hacksaw Coolant pumps are another common inclusion to help prevent the blades from overheating during use.
Can I put a metal cutting blade on my miter saw?
Although mitre saws were traditionally used for cutting wood, with the correct blade they can make light work of cutting through steel and aluminium profiles at an angle.
Can a carbide blade cut metal?
Tungsten carbide, called simple “carbide” in the building trades, is three times harder than steel; and when placed on circular saw blades, reciprocating saw blades and grinder discs, tungsten carbide cuts cleanly through steel.
