Design: M 42 - composition: W 2%, Mo 10%, V 1%, CO 8%, tooth hard-
ness: 68 HRC. For cuttingof materials up to 45 HRC
Design: M 51 - composition: W 10%, Mo 4%, V 3%, Co 10%, tooth hard-
ness: 69 HRC. For cuttingof materials up to 50 HRC
Design: Carbide - tooth hardness 1600 HV. For cutting of materials up to
62 HRC
In addition to standard shapes and sizes of teeth, the saw blades are also
manufactured with special features, such as saw setting, tooth angle and
tooth face shape, which are used particularly for cutting of specific materi-
als. Please contact your saw blade supplier to get more information about
these features.
Saw blade tooth arrangement
a) Constant - tooth edge spacing always equal.
b) Variable - the tooth edge space is different, repeating periodically. This
up-to-date saw blade design enables a bigger cutting range in one saw
blade type. It is able to eliminate vibrations caused by the tooth edge tou-
ching the material and thus to achieve a clean smooth cut and longer life.

The following table refers to piece-by-piece cutting of sections. If the material is cut in bundles, the forces of the walls of individual tubes must be added
with regard to their diameter.
6. Saw Blades
6.1 Saw blade design
The prerequisite of the correct cutting power of the machine is the use of
high-quality saw blades. In order to achieve a high cutting power, it is
recommended to use bimetallic saw blades. The main saw blade compo-
nent is the high-quality heat treated steel with a high elasticity limit. The
tooth edges are high-speed steel of the following quality: M 42, M 51.
M 42 - a saw blade for universal use for cutting metallic and non-ferrous
materials within the whole range of quality classes up to the 45 HRC hard-
ness. The saw blade is suitable for cutting full materials of all cross-sec-
tions and diameters, profiles, pipes and bundles.
M 51 - with reference to the M 42 saw blade, the M51 is designed first of
all for cutting steel up to 50 HRC, steel of higher strength classes, acid-resi-
stant and stainless steels, nickel, titan alloys and special bronze.
Carbide - high cutting power as compared to bimetallic saw blades.
Suitable for cutting of steel, non-ferrous metals, material with high content
of chrome, nickel, titan, stainless steel and face-hardened materials up to
62 HRC. The saw blades can be used for all materials including stainless
steel, tool steel, non-ferrous metals, cast iron, plastics and fibreboards.
These saw blades are characterized by a high thermal conductivity, high
wear and tear and thus longer life, higher cutting speed, less frequent saw
blade replacements and better productivity as compared with carbon steel
saw blades.
