CNC Calculator: Speeds Feeds

RPM, tap drill, taper, thread

Numbers you need standing at the machine, not at a desk.

• Feed and speed from material, tool and diameter — SFM and RPM, IPM and chip load
• Tap drill size for a thread, and the thread data behind it
• Taper, angle and offset for turning
• Bolt circle coordinates
• Unit conversion between inch and metric, including feed units
• Works with no signal
