Carmex MT9 MTB solid carbide thread mills with through coolant deliver precise BSPT threading in through-holes, built for reliable performance on CNC machines. Designed for shops that demand consistent BSPT bore threads, this tool combines robust carbide construction with modern cooling to keep tapping chatter low and finishes clean.

• Through-Coolant Bore: Coolant is delivered directly through the tool bore, enhancing chip evacuation and reducing heat buildup for deeper, more stable thread milling.
• Solid Carbide Construction: Provides rigidity and wear resistance for repeatable, high-precision BSPT thread milling in challenging materials.
• MT7 Shank: Standard Morse Taper size ensures secure toolholding and broad compatibility with common CNC spindles.
• Threading Range: BSPT threads from RC1/2 to RC7/8 x 14, enabling accurate internal threading across a wide size band.
• Designed for Through-Hole Applications: Optimized geometry and flute arrangement deliver clean starts, consistent pitch, and reliable performance in through-holes.

The MTB family represents a step forward in thread milling, prioritizing chip control and tool longevity without sacrificing precision. By enabling through-coolant threading, this tool reduces maintenance downtime and lowers overall tooling costs while delivering repeatable BSPT threads that meet tight tolerances. Ideal for production environments where BSPT bore quality and long tool life matter, it integrates smoothly with MT7 holders and standard CNC setups for a straightforward upgrade to coolant-assisted threading.
