Cutting Speeds

Determine the spindle speed for turning, milling, drilling, and reaming with these charts and cutting speed calculators.

The company is the world’s best Pipe Threading Lathes supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

Turning speeds are adjusted to the feed rate of the mini lathe (0.004/rev.), a depth of cut of 0.040, and a tool life of 180 minutes.
