The Sierras de Calar are the accessory used in the jigsaw machine. When selecting them we must take into account:

What material are we going to cut?

There are different compositions of the body of the Jig Saw with different performances depending on the material to be cut. We can find them in Carbon Steel, which due to its low hardness is good for cutting wood but its performance is lower in metal cutting. The jig blades developed in Bimetallic Steel They are suitable for cutting metals, since due to their flexibility and the hardness of the alloy they allow the cutting of metallic materials. Its performance is also optimal in wood cutting. Of course the cost of this alloy is higher than that of the Carbon Steel Saws, in general it is a profitable investment.

What fit does the machine have Jig Saw (or use starrett unified socket)?

There are different inserts that over time have tended to unify. Just the brand Starrett roulette online casino has the solution to this problem that for so long bothered users and sellers of Keyhole saw blades. Why? simple, when the user acquires a jigsaw blade in general he did not know the fit of his model of jigsaw machine. The result, many times the user reached the working point and when he tried to place the saw this did not fit. Problem for the user and problem for the seller.

What material should the teeth of the jigsaw be made of?

After defining the material to be cut and the insertion of the jigsaw machine, it is possible to advance in the definition of the material that should make up the toothing of the blade. There are three basic options:

  • High Speed ​​Steel Teeth: for cutting soft metals and wood
  • Ground Hard Metal Teeth: for cutting ceramic, porcelain and glass
  • Carbide-tipped teeth: for cutting difficult metals such as stainless steel

The material that makes up the tooth must be combined with the number of teeth per inch, which vary in different brands.

How many teeth per inch should the jigsaw have?

As a general rule we can say that “at the point of less thickness of the material to be cut, there must be at least 3 teeth in contact”. There are different combinations of teeth, both continuous pitch (the same number of teeth in each inch) and variable pitch (there are different numbers of teeth in each inch). Sharpening also varies, which can have a positive or negative angle and even those with special modifications in the thickness and shape of the blade body to allow curved cuts (scroll).
