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.
To achieve a smoother, more refined cut choose a blade that has more TPI. High TPI configurations should be used on thinner materials and may require a reduced material feed rate through the blade. Thicker materials require a low TPI blade, but may be fed through the blade at a higher feed rate. A regular tooth blade is available in higher TPI blades and produces smoother cuts in all woods.
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.
The wider the blade, the stronger the beam strength; therefore, a 1″ blade has far greater beam strength than a 1/8″ blade and will cut straighter and is more suitable for resawing. BLADE BACK- The back of the blade that runs on the back blade guide. BLADE MAINTENANCE- There is not very much that needs to be maintained on the blade, but below are a few points that will help you keep your blade in peak cutting performance.
Manufacturers recommend that at least three teeth and no more than 25 always be in contact with the workpiece. The blade chosen is based on the thickness of the material being cut, with a minimum of three teeth in the material.

how many teeth on bandsaw blade Related Question:
How many TPI does a bandsaw blade need?
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.
Is more teeth on a saw blade better for metal?
Are more teeth better? Generally, the higher the amount of saw blade teeth, the better the quality of cut and finishing. If you’re looking for a faster and rougher cut, then a blade with fewer teeth will be more suitable.
Is more teeth on a saw blade better?
The number of teeth on the blade helps determine the speed, type and finish of the cut. Blades with fewer teeth cut faster, but those with more teeth create a finer finish.
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.
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.
Is a wider bandsaw blade better?
The wider blades are stiffer overall (more metal) and tend to track better on the band wheels than narrow blades. When cutting thicker material, the wider blade has less ability to deviate because the back end, when in the cut, helps steer the front of the blade, especially if the side clearance is not excessive.
How many teeth do I need on my miter saw blade?
Normal miter saw blades will have a tooth count of 60-80. Lower tooth count blades of 50-60 are best for rough cuts to lumber. A precision blade for trim work will typically have a tooth count of 80-100. Therefore, miter saw blades should have between 60-80 teeth.
How many teeth do you need for plywood?
Cross-cutting wood or sawing plywood: Use a 40-tooth to 80-tooth blade. You can use a 40-tooth to 50-tooth general purpose blade as well. Joinery work: Use a 40-tooth to 50-tooth all-purpose combination blade. Cutting MDF and man-made materials: Use a 50-tooth to 80-tooth blade.
How many teeth should a circular saw blade have?
Generally, blades with more teeth will provide a smoother, finer cut whereas blades with fewer teeth will provide a rougher cut. The benefit of fewer teeth is faster cutting and a lower price. For most construction work, a 24-tooth general use blade is sufficient.
How many teeth does a Mitre saw have?
Miter-saw blades- 80 tooth.
How many teeth does a finishing blade have?
Here’s a quick and dirty list of different tooth counts and their typical use: 16-24 Teeth: Demo/Framing. 32-50 Teeth: All-Purpose Cutting. 60-80 Teeth: Finish Grade.
How many teeth per inch does a CrossCut saw have?
Each cutting tooth cuts with one edge and pushes the sawdust out with the other. Crosscut saws have 8 to 15 pointed teeth per inch.
How many TPI is a fine tooth saw?
Blades with 12 or more TPI are typically labelled as fine-toothed saws.
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.
What is a 60 tooth saw blade used for?
Honorable Mention: 60t or 80t Cross Cutting Blade A good cross cutting blade is designed to provide ultra-smooth cuts going across the grain without splintering or burning. And ultra-smooth cuts equate to better precision and tighter joinery in your projects. Generally, more teeth equals a better cut.
