Keyway Depth Calculator

Calculate exact cutting depths for shaft keyways and hub keyseats.

Inputs

Formulas used:
Chord Height (h) = (D - √(D² - W²)) / 2
Depth of Cut (C) = h + (H / 2)
Depths are strictly measured from the theoretical sharp edge (highest point on the radius) down to the flats.

Results

0.0000"
Overall Dimension Across Shaft to Floor
0.0000"
Chord Height (h) - Gap at Center
