Indexable Milling Cutters in Aerospace, Automotive, Medical and Mould Making
August 16, 2026 · Exactalloy Technical Team
Different industries buy the same tool family for very different reasons — cycle time, surface integrity, tolerance or tool life.
Quick answer: Aerospace demands edge integrity in titanium and Inconel; automotive demands cycle time in aluminium and cast iron; medical demands burr-free finishes in stainless and cobalt alloys; mould making demands dimensional accuracy in hardened steel.
Aerospace
Titanium and nickel alloys generate high heat at the cutting edge — use AlCrN-coated grades, high-pressure coolant and conservative surface speed.
Automotive
Cycle time rules. Aluminium and cast iron are cut dry or with air blast at high speed, and tool changes are pre-scheduled.
Medical
Cobalt-chrome and stainless implants require sharp, polished edges and burr-free finishes, often with dedicated deburring steps.
Mould and die
Hardened steel above HRC 50 is machined in small steps with high rigidity to achieve the required surface finish and corner accuracy.
Specifications at a glance
| Industry | Typical material | Key requirement |
|---|---|---|
| Aerospace | Ti-6Al-4V, Inconel | Edge integrity, surface integrity |
| Automotive | Aluminium, cast iron, steel | Cycle time, consistent life |
| Medical | Stainless, CoCr | Burr-free, fine finish |
| Mould & die | Hardened steel >HRC50 | Accuracy, surface finish |
Frequently asked questions
Which industry has the tightest requirements?
Aerospace and medical, because a surface-integrity failure cannot be inspected out afterwards.
Do I need different tools per industry?
The same geometry can serve several industries, but coating and substrate selection usually differ.
