Slitting saw speeds & feeds

For carbide slitting saws. Enter any tooth count from 1 to 400. The drawing shows the actual teeth and how many are in the cut. Feeds use the low end of each published range.

Machine profile

Stored in this browser only. RPM is capped at your max. The rigidity derates are our own conservative assumption, not a published figure. Default profile is 10,000 RPM / 5 HP / average until you change it.

    Did these numbers work?

    Numbers only change after several independent reports agree, and they stay inside the published ranges.
