Meet the Carmex Carbide Mini Thread Mill—MT7 shank, G1/8 x 28 with a 55° G thread form—designed to cut both internal and external G1/8x28 threads with exceptional efficiency. Built for high-speed machining across a wide range of materials, it delivers precise threads and shorter cycle times without compromising reliability.

• Thread form and size: G1/8 x 28 with MT7 shank and 55° G thread profile for accurate BSP/GSP applications.
• Material and coating: Sub-micron MT7 carbide with a Titanium Aluminum Nitride multi-layer coating (ISO K10–K20) that enhances hardness, heat resistance, and tool life.
• Cutting geometry: Spiral flutes and a short, rigid profile for smooth cutting action and reduced cutting forces.
• Flute count: Multi-flute design (3–5 flutes) enables faster material removal and shorter machining times.
• Coolant through flutes: Through-flute coolant improves chip evacuation and cooling in deep-hole threading applications.
• Hole and material versatility: General-purpose threading capability that works across a broad material range, including hardened workpieces up to 45 HRc.
• Deep-hole capability: Optimized for machining in deep holes, reducing tool deflection and improving accuracy.
• Versatility in threading: The same tool can produce a wide range of thread pitches and can thread both external and internal features.
• Longevity: Special triple coating and robust carbide construction contribute to longer tool life in demanding cycles.

This thread mill is ideal for shops that need reliable G1/8 x 28 threading with high productivity. It excels in deep-hole work, hardened materials, and scenarios where changing tools to cover multiple pitches or thread choices would slow production. With through-coolant and a compact flute design, you’ll experience cleaner cuts, fewer derailments, and consistent thread quality across batches. Perfect for precision aerospace, automotive, or medical-manufacturing environments where repeatable performance matters.
