OPEN WIZARD →How the Carmex Tool Wizard Works
Three steps. No guesswork. The wizard filters the full Carmex MT7 and MT8 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, Any Size
A single thread mill can cut multiple thread sizes and pitches — both internal and external. Fewer tools, lower tooling costs, less changeover time.
No Tap Breakage
Ideal for 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
Designed 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 MT7 and MT8 Thread Mill Range
Carmex Precision Tools is an Israeli manufacturer specialising exclusively in solid carbide thread mills. Founded in 1988, Carmex has built a global reputation for the MT7 and MT8 ranges — two of the most comprehensive thread mill series available in the market today.
The MT7 Mini Type is a multi-form thread mill that covers a range of pitches with a single tool. The MT8 Full Profile is a single-pitch thread mill for tight-tolerance precision threading applications.
Protool is an authorised UK stockist for Carmex thread mills, holding stock across the BXC and BXA 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 designed to help CNC machinists, engineers, and buyers identify the correct Carmex solid carbide thread mill for their threading application. By entering your thread form, workpiece material, and machine type, the wizard filters the full Carmex MT7 and MT8 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. The MT7 Mini Type is a multi-form thread mill that covers a range of thread pitches with a single tool, making it ideal for workshops seeking flexibility and lower tooling inventory. The MT8 Full Profile is a single-pitch thread mill engineered for tight-tolerance applications in aerospace, medical, toolmaking, and precision engineering, where exact thread form is critical.
Two carbide grades cover the range of machining applications stocked at Protool. BXC is the universal grade for general-purpose threading in steel, stainless steel, and cast iron. BXA is optimised for non-ferrous materials — aluminium, copper, and brass — with geometry and coating tailored to prevent built-up edge and deliver excellent surface finish in softer workpiece materials.
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. Call our technical team on 01732 887334 for advice on selecting the right Carmex thread mill for your application.
