Tapping Speeds
- Recommended Tapping Speeds and Cutting Fluids

This xhart shows the recommended tapping speeds and cutting fluids, Tap material, type of tap chamfer length, dimension of drill hole, work materials and cutting fluids are important factors for determining suitable tapping speed.
Lubrication, cooling, capability and adhesion Resistance are the three important factors effecting cutting fluid.
