Calculation of the correct tooth pitch when cutting pipes.

The attached formula based in our technicians experience, can be used to calculate the most suitable tooth pitch when cutting pipes.

 

Selecting the correct tooth pitch to cut Solids

CONSTANT TOOTH PITCH
 
Tooth pitch t.p.i/d.p.p. Contact length
     
24   6
18   10
14   15
10 15 30
8 30 50
6 50 80
4 80 120
3 120 200
2 200 400
1,25 300 800
 
VARIABLE TOOTH PITCH
 
Tooth pitch t.p.i/d.p.p. Contact length
     
10- 14   30
8 - 12 20 50
6 - 10 25 60
5 - 8 35 80
4 - 6 50 100
4 - 5 70 120
3 - 4 80 150
2 - 3 120 350
1,4 - 2 250 600
1,0 - 1,4 400 1000
0,75 - 1,25 700 1400
0,7 - 1,0 900 3000


  Constant tooth pitches are suitable for solid materials

  Variable tooth pitches are recommended to suppress the resonance phenomenons and vibrations
