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.
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.
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.
Band saw tooth size is determined by the size and type of material to be cut and the desired finish. Find material dimensions on bottom of chart and move up for appropriate teeth per inch. In general the following rule applies to choosing the speed of your band saw blade: The harder the material, the slower the speed; conversely, the softer the material, the faster the speed.
how many teeth for 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.
What TPI is best for cutting wood?
If you’re looking to cut wood or other soft materials, you’ll need a blade with a TPI of 6 up to 20. For harder materials like metal, a TPI between 14 up to 36 is more suitable. The number of teeth can be found on the blade.
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.
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.
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.
What is 18 TPI for cutting?
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. Pro Tip: Always keep 3 teeth in contact with the material being cut.
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 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 many teeth does it take to cut wood?
For most construction work, a 24-tooth general use blade is sufficient. That blade is very aggressive and will help you rip and cross-cut lumber and sheet goods quickly and with a high degree of accuracy. With a 24-tooth demo blade, you’re getting work done quickly, but you won’t get a near-finished edge.
How many TPI is a fine tooth saw?
Blades with 12 or more TPI are typically labelled as fine-toothed saws.
How many teeth should a circular saw blade have?
A 40-tooth blade works fine for most cuts through plywood. Blades with 60 or 80 teeth should be used on veneered plywood and melamine, where the thin veneers are likely to blow out on the underside of the cut, a characteristic known as tearout. MDF requires even more teeth (90 to 120) to get the cleanest cut.
What is a 60 tooth saw blade used for?
A crosscut blade, on the other hand, is designed to produce a smooth cut across the grain of the wood, without splintering or tearing. This type of blade will usually have 60 to 80 teeth, and the higher tooth count means that each tooth has to remove less material.
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 does it take to rip a hardwood floor?
Rip blades usually have 10 to 40 flat-topped (FT) teeth, which is a comparatively small number, but it will move through the grain quickly.
What is the best TPI for cutting EMT?
The Thin Metal Blade (12/14 TPI) is optimized for best-in-class cuts in thin/extreme metals such as unistrut or EMT conduit but also provides strong performance in tougher thick metals.
