Quantify what tool changes cost. Enter change time, tool life, machine rate and tool count to get the cost of one change, the minutes lost per day and the annual cost.
Let our engineers find the right factory for your specs. 100% Quality Guaranteed.

Modern VMCs: 1.5-3 seconds chip-to-chip. Older machines: 5-10 seconds. Manual tool changes: 30-120 seconds. At a $100/hour machine rate, every second of tool change time costs $0.028. With 200 tool changes per day, a 3-second vs 8-second change saves $35/day or $8,750/year.
Yes. Offline tool presetting (measuring length and diameter before loading into the machine) can reduce setup time by 50-70%. The machine stays cutting while the next job's tools are being preset. For shops running 5+ setups per week, a presetter typically pays back in 6-12 months.
For high-mix shops: yes. Capto/HSK quick-change systems cut tool change time from 2-5 minutes (manual) to 30-60 seconds. At 10 setups per week, the time savings alone justify the premium holders. For production shops running one part for weeks, the benefit is less -- standard holders suffice.
Enter the tool change time in seconds, machine hourly rate, and number of tool changes per day. The calculator shows the cost per change, daily downtime minutes, and annual production loss. Use these figures to build the business case for quick-change tooling or presetter investment.

Use the calculator freely. If the result points to a tooling or process problem, we can source the exact carbide tooling you need from vetted factories in China. Compare factory-direct pricing.
Before you commit to a spec, it helps to know what the market pays for it. These are real, publicly listed factory prices — not a quotation, and not a guess.
We source the tool families below direct from vetted Chinese factories, matched to the material and tolerance you just worked out. Every batch ships with its material certificate and dimensional record.

MEASURING TOOL-CHANGE LOSS? Frequent changes usually point at inconsistent tool quality rather than a bad process. See how batch-to-batch consistency is verified at the factory.
