OPEN WIZARD →How the Carmex Tool Wizard Works
Three steps. No guesswork. The wizard filters the full Carmex thread mill range and returns the exact tool for your job.
Select Your Thread Form
Choose your thread standard — ISO Metric, Unified (UN), BSP, NPT, Trapezoidal, Whitworth, and more. The wizard covers all major international thread forms.
Enter Your Material
Select your workpiece material — from mild steel, stainless steel, and cast iron to aluminium, titanium, Inconel, and hardened steels up to HRc 63.
Get Your Result
The wizard returns the exact Carmex part number, carbide grade, and cutting data for your application. Copy the specification straight to your order.
Why Use a Thread Mill Instead of a Tap?
Thread milling has become the go-to method for precision CNC threading. Here's why engineers are switching.
One Tool, Many Diameters
One thread mill cuts any diameter above its own size in the same pitch. Pipe-thread and partial-profile tools also cut internal and external threads with the same tool. Fewer tools, lower tooling costs, less changeover time.
No Tap Breakage
Suited to blind holes where tap breakage is a risk. Thread mills exit cleanly at the bottom of the hole without packing chips or snapping off in expensive workpieces.
Hard Material Capable
Solid carbide construction means Carmex thread mills handle tough materials that would destroy a conventional tap — including stainless steels, titanium alloys, and hardened engineering steels.
CNC Optimised
Built for CNC machining centres, Swiss-type lathes, and multi-tasking machines. Helical interpolation gives precise thread form control at high feed rates.
Left or Right Hand
Cut left-hand or right-hand threads from a single tool by changing the direction of helical interpolation — no need for separate LH tap sets.
Continuous Chip Evacuation
No chip packing. Thread milling continuously clears chips during the cut, reducing heat build-up and extending tool life — especially in stainless and exotics.
The Carmex Thread Mill Range
Carmex Precision Tools is an Israeli threading specialist. Founded in 1988, Carmex has built a global reputation for its solid carbide thread mills, covering ISO Metric, UN, BSP, NPT, Trapezoidal and Whitworth thread forms across a wide span of pitches.
MT7, MT8 and MT11 are carbide grades, not tool types. MT7 is the general-purpose grade, MT8 stands up to high heat, and MT11 is made for hardened steel, stainless and super alloys.
Protool is an authorised UK stockist for Carmex thread mills, holding stock across the MT7, MT8 and MT11 grades for same-day and next-day despatch to engineers across the UK.

Carmex Tool Wizard — Find the Right Solid Carbide Thread Mill for Your Application
The Carmex Tool Wizard is a free online selection tool that helps CNC machinists, engineers, and buyers identify the correct Carmex solid carbide thread mill for their threading application. Enter your thread form, workpiece material, and machine type, and the wizard filters the full Carmex thread mill range and returns an exact tool specification — including part number, carbide grade, and recommended cutting data — in seconds.
Carmex Precision Tools, founded in Israel in 1988, is a specialist manufacturer of solid carbide thread mills for CNC machining. Mini Type thread mills are built for small-diameter threads and confined spaces. Full profile thread mills cut a single pitch and the complete thread form, built for tight-tolerance applications in aerospace, medical, toolmaking, and precision engineering, where exact thread form matters.
Most of the Carmex thread mills stocked at Protool come in one of three carbide grades. MT7 is the general-purpose grade: sub-micron carbide with a TiAlN multi-layer coating, made to run at medium to high cutting speeds across all materials. MT8 is sub-micron carbide with a PVD triple coating that stands up to high heat and cuts smoothly in all materials. MT11 is ultra-fine sub-micron carbide with a blue PVD triple coating, for hardened steel, stainless steel, and super alloys.
Thread forms supported by the Carmex range include ISO Metric (M), Unified National (UN), British Standard Pipe (BSP and BSPT), National Pipe Taper (NPT), Trapezoidal (Tr), Whitworth, and others. Protool is an authorised UK stockist for the full Carmex thread mill range, with stock held in our Kent warehouse for same-day and next-day despatch across mainland UK.
