How to find the right Bandsaw blades
For our ready-made Bandsaw blades, the belt length x belt width x belt thickness and the tooth pitch (distance between the tooth tips in mm) are specified.
Example: 2240 x 16 x 0.65 x 2.4 mm
The right choice of Bandsaw blades
Wide Bandsaw blades with a larger tooth pitch (> 3 mm tooth spacing) are suitable for straight and right-angled cuts. The blade width stabilises the Bandsaw blades in the straight kerf and the larger chip space between the teeth enables fast removal of the sometimes long-fibre chips.
Narrow Bandsaw blades with a small tooth pitch (< 3 mm tooth spacing) are more suitable for curved and curved cuts. Depending on the radius, they do not jam in the saw cut. Due to the lower feed rate in curves, the smaller spaces between the teeth can clear the fibres from the kerf.
However, please note that the material, thickness of the workpiece, Cutting direction for solid wood, required radii and feed speed also have an influence on which Bandsaw blades are best suited to the project.
The band length of the Bandsaw blades
The band length varies depending on the machine size and model of the Bandsaws and starts at 1400 mm. The larger the bandsaw, the longer the Bandsaw blades. The required blade length is specified on the type plate of the Bandsaws. If you no longer have this dimension to hand and no longer have a used band saw blade, you can measure the required band length yourself. Set the upper deflection roller of the Bandsaws to a maximum of half the stroke height. Place a tape measure over the upper and lower guide pulleys as if it were a band saw blade. If you do not have a measuring tape of sufficient length, you can also use a cord (be careful not to stretch it!). In any case, make sure that the upper guide pulley still has enough stroke to tension the saw blade.
The bandwidth of the Bandsaw blades
The maximum and minimum bandwidth also depend on the machine size and model of the Bandsaws. The wider the Bandsaw blades, the more stable and straight it runs in the saw cut - especially when used for straight cuts. The narrower the bandsaw blade, the tighter the radii that can be sawn. Specialised bandsaws, such as fine-cut bandsaws, allow the use of saw blades just 1 mm wide for small radii. The minimum blade width for small standard Bandsaws is 3 mm.
Ratio of the strip width to the minimum sawing radius:
The band thickness of the Bandsaw blades
The thickness of the band has an effect on the straightness of the cut. The thicker the belt, the more stable and straight the Bandsaw blades will be when subjected to the stress of pushing and turning the workpiece. However, if the band material is too thick in relation to the Diameter of the deflection rollers, this would result in rapid material fatigue due to a lack of flexibility. As a rule of thumb, blade thickness = one thousandth of the roller diameter. Thanks to modern materials with high flexibility and toughness and sophisticated manufacturing processes, this formula is now only a guideline.
Tooth pitch on the Bandsaw blades
It is specified either as the distance between the tooth tips (Tooth pitch in mm) or as ZpZ (Teeth per inch - number of teeth over a Length of 25.4 mm) or TPI (Tooth per Inch). Tooth pitch influences the cutting quality and cutting speed.
The smaller the tooth pitch, the smaller the teeth. Bandsaw blades with a small tooth pitch are suitable for very fine cuts, thinner workpieces and harder materials. They leave fine cutting edges. However, the small spaces between the teeth mean that you have to work at a lower feed rate, as the Bandsaw blades need more time to remove the chips from the kerf.
Bands with a large tooth pitch, i.e. a greater distance between tooth tips, are suitable for rough cuts and high cutting performance. The large space between the teeth means that more chips can be removed from the kerf. These bands are suitable for edging boards or cutting firewood.

The band saw blade material
Bandsaw blades made of tool steel/carbon impress with their versatility and suitability for various materials. Depending on the toothing, they are ideal for softwood, hardwood, plastics and non-ferrous metals. Their flexible backing offers a decisive advantage over other materials such as Uddeholm (Uddeholm Arne) or Swedish steel. Bimetal band saw blades with designations such as M42 or M51 are used for particularly demanding uses in Steel and metalworking.
Special saw bands
Our range also includes customised products that offer incomparable advantages compared to conventional Bandsaw blades.
- Bandsaw blades with back serration:
For curved cuts, e.g. when cutting out thick shell blanks for wood turners. The additional toothing on the back of the band reduces friction in the curves and the band cuts freely.
- Fine-cutting band saw blades:
The world's finest bandsaw blades with a blade width x blade thickness from 1.02 x 0.36 mm. They enable Saws to cut tight curves with radii of less than 2 mm. The fine-cut band saw blades can only be used on the specially developed guide system.
Please note that Material, workpiece thickness, wood moisture and Cutting direction for solid wood, required radii, feed speed etc. also have an influence on the cutting performance and cutting quality. For special requirements, it may be necessary to test several bandsaw blades to determine the perfect one for you and your projects.
