Description
The Carmex MTB Through-Coolant Thread Mill is a solid carbide tool designed for precision Whitworth threading (BSW/BSF) with a MT7 shank. Built for demanding workshops, it combines robust cutting geometry with a through-bore coolant system to improve chip control and extend tool life.
- Through-Coolant Bore: Delivers coolant directly to the cutting zone via the bore, enhancing chip evacuation and temperature management for cleaner threads and deeper cuts.
- Solid Carbide Construction: High-hardness carbide provides rigidity, wear resistance, and stable, repeatable thread profiles under challenging cutting conditions.
- MT7 Shank: Standard MT7 interface offers secure, precise mounting in compatible tool holders for reliable performance at high speeds.
- Whitworth Threading (BSW/BSF): Engineered specifically for Whitworth screw threads with the size specification 5/8 - 11/16 x 14, ensuring accurate thread form and fit.
- MTB Through-Coolant Line: Part of Carmex MTB family, designed to deliver integrated bore cooling that reduces heat buildup and promotes longer tool life in threading operations.
This combination of through-coolant efficiency and carbide rigidity translates into smoother thread milling, reduced maintenance downtime, and cost-effective production of precise Whitworth fasteners. Ideal for automotive, machinery, and mechanical assembly applications where reliable Whitworth threading is essential.
