Cutting Speed Calculation
The cutting speed (vc) is calculated using the formula:
vc = (π x d x n) / 1000, where:
- n = Speed (1/min)
- d = Tool diameter (mm)

HSS Bi-Metal Hole Saws – Speed Chart
Questions often arise regarding the material thickness to hole diameter ratio (S/D ratio). Traditionally, the punch die should be equal to or larger than the material thickness. However, this rule does not apply to hydraulic punching units like ALFRA APS, which allow for a punch diameter smaller than the material thickness.

However, this rule does not apply to hydraulic punching units like ALFRA APS, which allow for a punch diameter smaller than the material thickness.
Thickness/Diameter Ratio
Chart 1 provides guidance on the appropriate thickness/diameter ratio based on trials. For example, for S235 steel, the recommended ratio is 1:1.3, with an upper limit of 1:1.7. Exceeding this ratio may reduce the punch's lifespan.
