Description
The Carmex carbide thread mill with through-coolant delivery is engineered for precise internal threading in through-holes, delivering coolant directly to the cutting edge for smooth, efficient machining. Designed for Whitworth BSW/BSF threads (3/8" diameter, 16 TPI) and MT7 spindles, it fits a wide range of machines and setups.
- Thread size: 3/8" diameter, 16 TPI Whitworth (BSW/BSF) for classic imperial thread forms
- Through-coolant delivery: coolant flows through the flute channels directly to the cutting edge for improved cooling and chip control
- Flute design: optimized flute geometry supports direct chip evacuation from through-holes
- Material: carbide construction for high hardness, wear resistance, and long tool life
- Shank compatibility: MT7 Morse Taper shank for secure, rigid engagement in suitable spindles
- Application: ideal for threading through holes with clean breakouts and precise thread profiles
- Machining performance: consistent thread form and reliable finish under production conditions
With through-coolant threading, you gain better heat management, reduced chip buildup, and enhanced tool life, even in deep or challenging through-hole applications. The carbide construction delivers stiffness and durability for repeatable, high-quality threads, while the MT7 shank ensures a stable, accurate cut. This tool is a practical choice for shops seeking precise Whitworth threading and efficient, coolant-assisted milling without compromising on reliability.
