Carmex’s Mini Type Through-Coolant Thread Mill delivers precise internal threading in small-diameter holes, built for engineers and machinists who demand reliable, high-quality M2.5 x 0.45 threads. Designed around Carmex’s solid carbide MTSB concept, this cutter combines compact geometry with efficient cooling and chip evacuation.

• Type: MTSB solid carbide thread milling cutter with an internal cooling bore for through-coolant operation
• Coolant Delivery: Through-coolant bore provides high-pressure coolant through the tool into the pre-hole, flushing chips away during the threading circle and stabilizing the cut
• Thread Geometry: Metric M2.5 x 0.45 threading profile optimized for small-diameter holes
• Material: Solid carbide for exceptional wear resistance and long tool life in tough materials
• Shank / Interface: MT7 shank compatibility for versatile machine integration
• Design Benefit: Mini Type construction suited for tight spaces and delicate pre-holes without sacrificing rigidity or accuracy

This through-coolant technology minimizes thermal loading on the cutting edge, reduces built-up edge, and improves surface finish of the formed threads. The optimized coolant flow also enhances chip evacuation, helping to maintain dimensional accuracy throughout the threading cycle. Ideal for precision aerospace, automotive, and manufacturing applications where small, reliable threads are essential.
