Band saw cutting blades appear in many different widths, tooth designs, components, and styles. KMS Equipment has a wonderful choice. Click here to start out buying now. Or read on to understand more about picking and using band saw cutting blades.
We make use of the phrase “width” but really it comes down to 2 things: The highest capacity your band saw can accommodate and the minimal radius you need to cut. Start with contacting the manufacturer’s directions.
When you are carrying out re-sawing, cant or cut-off sawing, make use of your band saw’s optimum blade size. This will keep your reductions nice and direct and you will have a reasonable give price without breaking cutting blades.
On the other side of the scale, should you curve sawing, use a blade which is filter enough to cut the required radius. The graph or chart below shows the connection between blade thickness and the minimum radius it would cut.

Selecting the proper thickness in the blade is important. Continual flexing and heating and air conditioning leads to metal exhaustion and finally, breakdown.
The size of your blade is determined by the size of your rims, and the try to be performed. Thick cutting blades stand up to much more slicing strain from directly cuts but will crack quicker in the bending and twisting measures. Slimmer rotor blades perform well for lighter weight work. These chart displays perfect blade density for a variety of wheel diameters.
In figuring out teeth per inches (TPI), look for an equilibrium accomplish and supply price. Rotor blades with increased teeth cut reduced and easier. Blades with a lot fewer the teeth cut quicker, with slightly rougher accomplish.
For any kind of accuracy and precision decreasing, the principle is always to usually keep at least three tooth inside the materials always. This adds steadiness and reliability and applies to cutting within both metal and wood.
Use coarse teeth cutting blades (2 or 3 TPI) for re-sawing and reducing heavier materials. For standard wooden cutting obligations in standard 3/4″ material, make use of a 4 TPI blade for coarse, fast slicing plus a 14 TPI blade for slow, softer cutting. A blade inside the 6 to 8 TPI array provides great basic-objective overall performance. This same equation is true whether you’re cutting timber or metal. For thinner materials and plastic materials under 1/4″ work with an even finer blade (18 – 32 TPI).
You will find three simple teeth styles in band saw cutting blades: standard, skip and hook.
Skip teeth blades have widely spaced the teeth in a degree rake angle to avoid blocking when reducing smooth hardwood, non-ferrous alloys and plastic materials.
Connect teeth rotor blades possess a much deeper gullet—that is, bigger teeth—and a confident 10 education rake angle. This helps the blade to feed in the materials more assertively. The result is more quickly cutting charges. Connect teeth cutting blades are generally employed for long reductions in heavier timber, hard wood, plastic-type material and metal.
Factor Pitch rotor blades have switching sets of distinct measured the teeth to supply a fast cut using a smooth complete, well suited for joinery and decreasing contours.
You will notice a blade’s set by searching on the the teeth.
A raker tooth set up has one teeth going to the remaining, a single to the right, followed by a direct, or unset, tooth, which is named a raker.
An alternate tooth set has a single teeth proceeding still left, one moving appropriate, then kept, right, and so on. There is no raker teeth. The increase swap plus raker has a unset raker tooth following two left-proper combinations.
A wavy tooth established has teams of the teeth establish left and right, split up by unset raker teeth. Curly established rotor blades are produced primarily with all the modest the teeth appropriate for reducing finer metal parts, pipes, water lines, slender bedding, and so on.
Blade Set up
Picking a suitable set up gives a balance between sawdust and air inside the room in between the body in the saw blade and the materials it is actually cutting. An excellent correct set is approximately 80/20, with 80% sawdust and 20% atmosphere getting ejected. The sawdust needs to be cozy to touch, not hot or cold.
An excessive amount of set up contributes to excessive oxygen rather than enough sawdust and will depart teeth markings.
Not enough establish restricts airflow and boundaries the blade’s ability to move sawdust in the cut. This results in popular, packed sawdust and results in short reducing periods and premature blade breakage. This is certainly concerning the most awful thing you can do for the band saw blade.
Excessively under set up bands will cut in the curly motion.
More accurately, this should actually be known as flutter setting. The goal is to set the proper stress in the much more powerful way, even though the band saw is working. Though manufacturer-precise, the manufacturer’s suggested adjustments and modifications often really need to be tweaked as a way to eliminate shake and achieve the best possible overall performance.
When you’ve altered the tension, shut down the machine, re-install the manuals and begin sawing.
Rotor blades get very hot from slicing. They expand and agreement and, as time passes, can also around tension their selves. Like getting a smooth area on your own tires from sitting in one particular area for too much time, leaving behind your blade under tension, strapped across the generate rims, results in a memory from the metal that could lead to early breakdown from metal low energy. Departing the band tight on the saw also distorts the crown and flattens the drive tires, leading them to be very difficult. Pressure also tensions the engine, shaft V-belt and generate pulleys.
Then when you’re finished slicing for the day, generally discharge blade stress. Record just how many changes you need to release tension so you won’t have to maintain undertaking the flutter analyze every time you would like to make use of the saw.
In no way use drinking water being a lubricant on band saw blades —or any other rotor blades, for that matter. Drinking water is not really a lubricant. It can oxidation and injury your body and gullets from the band saw blade along with the material being cut.
There are many of products accessible that are designed to specifically to lubricate blades, portions and cutting tools. Bostik tends to make an aerosol known as Dri-Cote, which lubricates and shields all kinds of slicing resources having its dried up movie technological innovation.
There are sound compound decreasing cafes and stays that you manage against the blade to add lubrication. Be sure to decide on a merchandise that won’t spot your hardwood and it is appropriate for your planned use.
Nearer to house you can find a number of time-analyzed goods that operate just the thing for lubricating your band saw rotor blades, and it’s connected parts.
Combine some great-adhesion chainsaw bar essential oil 50/50 with kerosene or diesel energy. Always apply lubricant to Each side in the blade. You will immediately discover a quieting effect as soon as it is applied. Re-apply about every 4-a few minutes when the noise of reducing improves yet again. This concoction is reported to supply longer band life, in addition to prevent corrosion, pitting and pitch accumulation!
One other exciting merchandise useful for band lubrication is PAM the squirt-on veggie shortening used in cooking. It is an incredible merchandise for rotor blades 3/4″ and under on top to bottom band saws. Disconnect the machine, spray PAM on a cloth and clean each side from the blade when switching top of the wheel by hand.
Yet another recommended item is WD-40. A big component of WD-40 is solvent, thus it dries quickly.
Whichever approach you use, lubricating your band saw blade body can boost its life by above 30 percentage. In each of the above instances, when utilized moderately, you are able to cut class lumber without discoloration.
