Calculating Tool Cost per Part
October 4, 2026 · Exactalloy Technical Team
Calculating Tool Cost per Part is a procurement problem as much as a technical one. This guide covers the process, the documents and the traps.
Quick answer: Buy on total cost of ownership, not unit price: include freight, duty, regrinding cycles, tool-change downtime and scrap rate in every comparison.
What good looks like
A supplier who answers technical questions with data, ships on the promised date, and holds batch-to-batch consistency.
Documents to request
Inspection report, material certificate, coating specification, packing list and, for export, the correct HS code and certificate of origin.
Common traps
Quoting on price alone, ignoring lead-time variability, and failing to standardise so that every job uses a different tool.
How to start
Run a pilot order with a defined acceptance test, then scale on measured results.

Frequently asked questions
Should I single-source?
Single-source for standardisation and volume pricing, but keep a qualified second source for continuity.
How do I compare quotations fairly?
Convert every quotation to cost per part on your own cycle time and scrap assumptions.
