Doubling tool life on a high-volume line can save thousands annually. For example: a $50 tool lasting 100 parts vs 200 parts saves $0.25/part. At 100,000 parts/year, that's $25,000 in tooling cost alone — plus reduced downtime for tool changes.
Premium coatings (AlTiN, TiSiN), optimised speeds and feeds (start at 80% of maximum recommended SFM), improved coolant delivery (through-tool coolant at correct pressure), and reduced runout are the four biggest levers.
Not always. If a premium tool costs 3× more but lasts only 2× longer, the cheaper tool may have better economics. Use this calculator to compare total cost per part, not just tool life in minutes.
Enter the tool cost, old tool life (parts per edge), new tool life, and annual production volume. The calculator shows savings per part and projected annual savings from the tool life improvement.

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.

Tool life is where the economics really live… Our guide covers why a test cut beats any certificate — and what a sample does and does not prove about the production lot.
We source carbide cutting tools from China for job shops. We do not own a factory, which is why we can quote your drawing against two or three plants that actually run your material.
