Materials of band saw blades for metal

Bimetal band saw blade

A strip of HSS high-speed steel with a hardness of 67–69 HRc is laser welded onto a spring steel backing. This type of band saw blade is the most widespread and offers the best price/performance ratio. Its performance and service life are strongly influenced by the quality of the material used and also by the thickness of the HSS wire welded onto the spring steel. The thicker the wire, the larger the area protecting the tooth tip against chipping due to impacts or vibration – but also the higher the price of the blade. A cheap blade for less demanding, price-oriented users therefore has only a small HSS tip made from expensive material and thus lower service life. Other factors that affect the application, service life and productivity of a bimetal blade are in particular the geometry, tooth rake angle, tooth set (kerf), hardening and tempering of the teeth and the quality of the weld. This blade has excellent resistance to vibration and impact.

Example of a professional band saw blade: 3660/27x0,9/ 4/6 - XP series metal-cutting band saw blade

Example of a band saw blade for hobby use: 1140/13x0,65/ 8/12 - Epic GP series metal-cutting band saw blade

It also has the widest range of applications:

From cutting non-ferrous metals and structural steels through die steels, cast iron, stainless and tool steels to the hardest nickel and titanium alloys.

Carbon steel band saw blade

This is a relatively inexpensive but now practically unused type of band saw blade for cutting metal. A band made from carbon steel has milled and set teeth that are hardened to approx. 64 HRC (Rockwell). This blade can only be used for cutting low-strength steels and its life is very short compared to bimetal blades. However, they are used for cutting wood and non-ferrous metals, where the cutting edge is not subjected to such extreme loads and their price makes them an optimal choice for this purpose.

Carbide band saw blade

Teeth are milled into a spring steel backing and a pellet of tungsten carbide with a hardness of 92 HRc is welded onto each tooth tip. The tooth is then ground to the required shape, most often using TripleChip geometry, where one tooth is roughing and the next is finishing. With this band saw blade it is possible to cut very productively, but its price is several times higher. It is also used for cutting very hard or tough materials that cannot be cut with a bimetal blade, for non-ferrous metals and for very abrasive materials such as aerated concrete or fireclay. In addition to the higher price, another disadvantage of this band saw blade is its lower resistance to vibration – in the event of impact or careless handling there is a risk of tooth breakage and thus destruction of the entire blade. Another type is the C-Grit band saw blade with a grit edge, which is designed for unusual materials.

• We do not list carbide blades in the e-shop because we want to be sure that the blade will work correctly for you. That is why we help you choose the ideal band saw blade for your specific application. Take advantage of our many years of experience and contact us – contacts.
