The band saw blades come in various widths, material, tooth design, and the configuration. You may want to look at this brand ryobi band saw first in order to get more insights on this topic.
Choosing a right width
We often use this word width yet really it is divided into 2 parts: The maximum ability your bandsaw could accommodate as well as minimum radius that you like to cut. Manufacturers’ instructions need to be consulted as well.ba
If you’re doing kind of re-sawing, sawing or cant, you should use the blade with the maximum width that your machine could allow. This may keep the cut straight and nice and you will get decent feed rates without breaking your blades.
But in some other cases, if you just do the contour sawing, then you will like to use blades that are narrow enough in order to cut your desired radius. You should look for the chart showing correlation between the blade width and minimum radius that it would cut.
Band saw blade thickness
Picking the right thickness of your blade is really important. Continual heating, cooling and heating leads to metal fatigue as well as ultimately, failure.
It is easy to find that the blade thickness will depend not only on the wheel’s diameter but also on the work that it has to be performed. The thick blade withstands much cutting strain coming from the straight cut but may break easily from just the twisting and bending action. The thinner blade is recommended for kind of lighter work.
The number of teeth needed
Getting the balance between decent feed ratesand the good finish are the 2 objectives in deciding how many teeth or TPI an inch you need to use. It is true that more teeth will make smoother yet slower cuts. Fewer teeth could allow for much faster cutting yet with a somewhat rougher finish.
For some kinds of the precision cutting, you need to know the thumb rule that is to at all times try to hold 3 teeth at least in your material. This will add stability and applies and accuracy to the job of cutting in wood as well as metal.
The coarse tooth blade of two or three TPI need to be utilized for thicker materials and re-sawing. For the typical wood cutting duty in normally ¾ inch material ranging between 4 teeth for fast, coarse cutting and 14 teeth for smoother slower cutting. Something ranging between 6 and 8 will be a nice purpose blade. The same equation will be applied if you are cutting metal or wood. A finer eighteen –32 tooth count need to be utilized for plastics below 1/4″ and thinner metals.
Tooth sets and styles
There are 3fundamental tooth styles you could find in bandsaw blades, the regular, hook and skip one.
The regular tooth blade has spaced teeth in a proportional way and are best suited to general aim blades for both contour sawing and cut-off. This kind is often utilized for cutting the thin material and where the fine finish may be required.
Teeth on the skip tooth blade are widely spaced as well as have a zero° rake angle in order to prevent against clogging as cutting the non-ferrous metal, plastics and soft wood.
The hook tooth blade has a deeper larger or gullet tooth as well as a positive ten° rake angle that will help its blade to go along well with the material. The result of that will be the faster cutting rate. The hook tooth blade is commonly utilized for the long cut to thicker wood, plastic,hardwood and metal.
The variable pitch blade has sets of teeth’s different size to offer both fast yet smooth finish cuts and are oftentimes utilizedfor cutting the curves and in joinery.
What will be the proper set?
The right set means the best balance between air and sawdust in space between saw blades’ body and the materialsthey are cutting. A nice appropriate set will be about 80/20 that includes 80 percent sawdust and 20 percent air being emitted. The sawdust need to be warm in order to be touched, not cold or hot.
A large amount of set will result in lots of air and not adequate sawdust and then will leave marks of teeth.
