Tooth Forms The tooth forms of the WIKUS program differ with respect to the rake angle of the cutting teeth and the root.
Raker tooth (S) Rake Angle of 0o, suitable for: short-clipping materials steels with high carbon content mainly tool steel and cast iron work pieces with small cross     sections thin-walled profiles Raker tooth (S) is available in constant tooth pitches of 3-32 tpi and in the variable tooth pitches of 3-4 tpi to 10-14 tpi.
Hook tooth (K) Positive rake angle, suitable for: long-chipping, tough materials mainly non-ferrous metals and steels with a carbon content < 0.8% structural steels, deep drawing steels, tempered steels, rust and acid-resistant steels and exotic alloys large cross-sections Hook tooth (K) is available in constant tooth pitches of 0.75-6 tpi and in the variable tooth pitches of 0.55-0.75 tpi to 4-6 tpi.
Skip tooth (L) Rake angle of 0o, suitable for: brittle material larger cross-section Skip tooth (L) is available in constant tooth pitches of 2, 3, 4 and 6 tpi.
Trapezoidal tooth (T) Positive rake angle, suitable for: high sawing performance for the greatest of band sawing demands Trapezoidal tooth (T) is available in variable tooth pitches of 0.85-1.15 tpi to 3-4 tpi.
Tooth pitch (Tz) Tooth pitch is defined as the number of teeth per inch (tpi). 1 inch equals 25,4 mm. In the WIKUS range, a difference is made between constant tooth pitches with uniform tooth spacing and variable tooth pitches with different tooth spacing within one toothing interval. Variable tooth pitches are marked by two dimensions, e.g. 2-3 tpi. With this, 2 tpi signifies the maximum tooth spacing and 3 tpi signifies the minimum tooth spacing in the toothing interval.
Types of tooth set Free-cutting action of the bandsaw blade is achieved by setting the teeth to alternately protrude to the left and right beyond the level of the band body. Raker set (SD) Toothing interval Standard tooth set can be universally used for cutting thicknesses of more than 5 mm (3/16") with steel, castings and hard non-ferrous metals. With constant tooth pitches, the set sequence is left/right/straight (fig. 1). With variable tooth pitches, one tooth is unset per toothing interval. The remaining teeth in the interval are recurrently set left/right (fig 2). Group set (GS) For bandsaw in the tooth pitch range of 4-18 tpi, improved surface quality is obtained with the group tooth set. Right-left set (RL) With materials easy to machine, such as non-ferrous metals, plastics and wood, a right/left wood, a right/left tooth set is especially effective. Wave set (WS) With material dimensions up to 5 mm (3/16"), such as sheet metal, thin-walled pipes and profiles, we recommend the wave tooth set.
