Meet Carmex MTB through-coolant thread mills: precision solid carbide tools engineered for BSPT threading with an MT7 shank. Designed for RC1/8 x 28 threads, they deliver consistent performance in compact, demanding machining environments.

• Through‑coolant bore: coolant is delivered directly to the cutting edge, helping flush chips from the bore and control heat for cleaner, more accurate threads.
• Solid carbide construction: rigid, wear‑resistant substrate provides reliable performance and long tool life in precision threading applications.
• BSPT thread geometry: specifically configured to produce RC1/8 x 28 BSPT threads with stable, repeatable profiles.
• MT7 shank: compatible with MT7 holders for strong gripping force and reduced runout in demanding setups.
• Efficient chip evacuation: fine-flute design and cutting geometry optimize chip removal, minimizing recutting and surface imperfections.

The MTB through-coolant design helps you maintain steady throughput by reducing heat buildup and ensuring consistent thread quality from first cut to last. With extended tool life and fewer interruptions for coolant-related issues, this Carmex tool is well suited for precision BSPT threading tasks such as fittings, adapters, and instrumentation housings where tight tolerances and reliable results matter.
