Calculate SFPM and TPM for Wood Band Saw Blades

Calculate SFPM and TPM for Wood Band Saw Blades

on

With wood band saw blades, speed is typically defined as feet per minute, commonly measured as SFPM, Surface Feet Per Minute (sometimes just SFM).

 

Calculate Band Saw Blade Surface Feet per Minute (SFPM)


SFPM = WHEEL RPM X WHEEL DIAMETER (in feet) X 3.14​ (a.k.a. Pi)

In addition to SFPM, you can also calculate teeth per minute (TPM).


SFPM Relationship to TPM:


  • SFPM impacts TPM directly since higher blade speed increases the number of teeth passing through the material.


Calculate Band Saw Blade Teeth per Minute (TPM)


TPM = SFPM x TPI (Teeth Per Inch)


TPM represents how many saw "teeth" hit the material in one minute. Calculating TPM allows the operator to determine the right blade pitch and feed rate to ensure the blade is not being overloaded or underutilized, which can lead to blade damage or suboptimal cutting performance.

KASCO's wood band saw blades have precision ground teeth for straight and accurate cuts, made from only the highest quality materials to improve performance, increase blade life, and decrease safety hazards for employees.

Whether you're cutting hardwood, softwood, frozen wood, or exotic lumber, our blades are built to withstand the rigors of heavy-duty operations in sawmills.
