Description
Carmex's Thread Mills Solid Carbide with Through Coolant is a precision threading tool designed for Whitworth threads (BSW/BSF) in a compact 3/8" diameter with 16 TPI, mounted on MT7 tooling. Building on the MTB concept, this through-bore coolant version optimizes chip evacuation and cooling to boost both performance and tool life in demanding precision work.
- Size and Thread Form: 3/8" diameter, 16 TPI Whitworth threads (BSW/BSF) for accurate, compatible cutting of classic British standards.
- Material: Solid carbide for exceptional hardness, wear resistance, and long tool life in tough machining conditions.
- Through Coolant Bore: Coolant is delivered through the bore to the cutting edges, enhancing cooling and ensuring steady chip removal.
- Shank Type: MT7 Morse taper shank for secure, rigid toolholding on compatible machines.
- Flute/Geometry Design: Optimized geometry tailored for reliable thread milling of Whitworth forms, delivering clean, consistent threads.
- Chip Evacuation: Enhanced chip clearance reduces risk of built-up edges and improves surface finish in deep or long-depth cuts.
Through-coolant delivery paired with carbide durability delivers more consistent thread quality, reduced tool wear, and improved productivity on Whitworth threading jobs. This tool is ideal for restoration, repair, and production work involving legacy British-standard components, automotive parts, and gear or valve assemblies where precise 3/8" x 16 Whitworth threads are required. Expect reliable performance, longer tool life, and cleaner thread surfaces under demanding machining conditions.
