The Carmex MTB Solid Carbide Thread Mills with Through Coolant are engineered for precise BSP/BSPT and BSF thread milling in tight spaces, delivering clean, repeatable G-thread profiles with enhanced reliability.

• Through-Coolant Bore: Coolant is delivered through the bore to the cutting edge, improving chip evacuation and cooling for deep or through-hole threading.
• Solid Carbide Construction: Built for rigidity and wear resistance, maintaining thread accuracy across demanding materials.
• 55° Thread Form: Specifically designed to match the G (Whitworth-style) thread geometry, ensuring accurate and consistent thread profiles.
• Thread Size and Shank: G1/8 x 28 with MT7 shank, compatible with standard CNC tool holders for quick and stable setup.
• Optimized Geometry: Flank and flute design tuned for efficient material removal and reduced built-up edge during threading.

This through-coolant threading solution directly addresses common challenges in miniature thread milling: chip clogging, overheating, and tool wear. By delivering coolant through the tool, it promotes smoother cutting, longer tool life, and the ability to maintain higher feed rates with better surface finish. The MT7 shank ensures solid seating and minimal runout, making it a dependable choice for precision shops that frequently produce small-diameter BSP and BSF threads. In practice, you’ll experience cleaner threads, fewer reworks, and improved productivity in automotive, plumbing, and instrumentation projects where tight tolerances matter.
