Spanwerk

Spanwerk is the fast cutting data calculator for metalworking – designed for metalworkers, machinists, apprentices, and hobbyists.

Select the material, enter the diameter – and you're done. Spindle speed and feed rate are displayed instantly. No looking up, no poring over tables, no internet required.

WHAT SPANWERK CALCULATES

• Drilling – Spindle speed, feed rate, material removal rate, cutting power, torque

• Turning – Spindle speed, feed rate, cutting force, power

• Milling – Spindle speed, feed per tooth, feed rate, power

• Tapping – Synchronous spindle speed/feed rate, core drill diameter

• Reaming & Countersinking – Suitable cutting parameters

• ISO 286 tolerance calculator – Fits H/h/g/f/k/n/p, IT5–IT11

CLEVER AND PRACTICAL

• Material database with guideline values ​​for steel, stainless steel, cast iron, aluminum, brass, copper, bronze, titanium, and plastic

• Automatic cutting speed and feed rate – depending on material, tool (HSS/carbide), diameter

• Switchable between roughing and finishing

• Conventional machine or CNC – conventional rounds down to actual spindle speeds

• Simple mode for quick values, professional mode for all parameters

• Favorites for recurring jobs

• Completely offline No advertising, no registration, no data collection

All values ​​are recognized guidelines (Kienzle, ISO 286). If in doubt, refer to the manufacturer's tool data sheet.
