What metals can the M42 band saw cut?
One of the most widely used band saw blades is the M42 non-metal band saw blade, the M42 model can cut a wide range of ferrous and non-ferrous metals. And we will introduce its cutting materials.
Bimetal M42 has spring steel body material and high-speed steel tooth tip material (HSS M42 – 1.3247), the hardness of its tooth tips is usually 68 Rockwell C (68 HRc.) with an approximate amount of 4% chrome, M42 models can All kinds of materials with HRc hardness. Cut 45~50.
Introduction of M42 band saw blade angle
۰ degree angle: the smallest tooth angle is 0 degree angle, the amount of chipping in this tooth angle is very small. Therefore, it is suitable for cutting all types of pipes and profiles with low work meat and non-alloy steels and light alloy steels (low alloy) with small and medium cross-sections.
۶° tooth angle: Usually, the blade of profile band saws has a 6° tooth angle. In addition to the 6° tooth angle, profile band saw blades have a special design for better performance in cutting pipes and profiles.
Tooth angle 10 degrees
The most widely used angle of the band saw blade for cutting solid sections is 10° angle. Filing and penetration of the blade of band saws with a tooth angle of 10° is excellent. M42 band saw blades with a 10° angle can cut a wide range of alloy steels with small, medium and large sections.
Tooth angle 16°: The most chip carrying and penetration among the band saw blade is the band saw blade with a tooth angle of 16°. The M42 band saw blade with a tooth angle of 16° can be used to cut all kinds of hard alloy steels with a large cross-section, all kinds of industrial pipes with high thickness.
The angle of the teeth is 10 degrees, sharpened from the back. : The teeth can be sharpened from the back. improve the chipping performance and increase the penetration in steel. It is better than the sharp back with a tooth angle of 10 degrees. To be used for cutting all kinds of alloy and super alloy steels with medium and large cross section.
The tooth angle is 16 degrees sharpened from the back: the most powerful tooth is the M42 model. And it has the ability to cut all types of alloy and super alloy steel, such as steel with nickel, chrome and titanium bases and other similar steels.
Tip: For better results, column band saw machines should be used.
Types of M42 teeth
Fixed tooth: this type of tooth is mostly used for cutting non-ferrous and non-ferrous metals such as aluminum, copper, brass, etc. in vertical band saw machines, the stability of the tooth makes resharpening easier.
Variable tooth: the most widely used type of band saw blade tooth is the variable tooth, in addition to being able to cut a wider cutting range, variable teeth have much less vibration when cutting and naturally less cutting noise than band saw blades with They have fixed teeth.
M42 bimetal left and right types
Vario Set: The most popular and widely used left and right band saw blades are the Vario Set. In this arrangement, it is usually repeated two or three times left and right and one tooth is placed directly. This type of tooth is used to cut a wide range of steels.
Raker Set: In this type of teeth, one tooth tends to the left and one tooth to the right. The third tooth is placed directly. This tooth type is used for cutting very hard alloy and super alloy steels.
Recommended materials for cutting
All kinds of construction steel such as iron beams, corners, studs, etc.
Types of steel pipes
Fine-cut steels (automatic)
Heat treatable alloys (VCN – MO40 – CK45)
Non-ferrous metals such as copper, brass, bronze, aluminum, etc.
Steels with internal tension less than 1400N/mm2
