Carmex Tool Wizard
Answer three questions. Get the exact thread mill you need — every time.
Launch the Carmex Tool Wizard →What is the Carmex Tool Wizard?
The Carmex Tool Wizard is a free online selection tool that takes the guesswork out of choosing the right thread mill. Designed for CNC machinists, programmers, and engineers, it guides you through your application requirements — thread form, material, machine type — and instantly recommends the correct Carmex solid carbide thread mill from the full MT7 and MT8 range.
How It Works
Select Your Thread
Choose your thread form — Metric, UN, BSP, NPT, Trapezoidal, and more.
Enter Your Material
From mild steel and stainless to titanium, Inconel, aluminium, and hardened alloys.
Get Your Result
The wizard returns the exact tool part number, grade, and cutting data for your job.
Why Use a Thread Mill Instead of a Tap?
- One tool cuts both internal and external threads across a range of sizes
- Ideal for blind holes — no risk of tap breakage
- Works in hardened materials (up to HRc 63) where taps fail
- No chip packing — thread milling evacuates chips continuously
- Better suited for CNC machining centres and Swiss-type lathes
- Full thread form control — left or right hand threads from a single tool
