Introducing the Carmex Thread Mills Mini Type — a through-coolant, solid carbide thread milling cutter built for precise internal threading in tight pre-holes. Designed for engineers and machinists who demand consistent thread quality and reliable coolant management in challenging materials.

• Mini Type form factor: Compact cutter profile optimized for small-diameter threads and constrained spaces while preserving full thread geometry.
• Thread size and forms: Supports 1/4" x 28 UN standard threads (UNC, UNF, UNEF, UNS) for versatile internal threading.
• Through-coolant bore: Internal coolant channel feeds high-pressure fluid through the tool to the pre-hole, aiding chip washing and edge cooling.
• MT7 shank: Reliable MT7 shank compatibility for secure, rigid engagement with high-precision machine tools.
• Solid carbide construction: Durable, wear-resistant material that maintains accuracy under aggressive cutting conditions.
• Chip control during threading: Coolant-assisted operation helps evacuate chips continuously during the threading circle, reducing buildup and improving surface finish.

By combining a through-coolant system with a rigid carbide core, this Carmex cutter delivers cleaner threads, longer tool life, and more stable performance across a range of materials. Ideal for internal threading in engine blocks, housings, manifolds, and other components with tight holes. The through-coolant design minimizes heat-related wear and ensures consistent tool life, while efficient chip evacuation cuts down on rework and improves first-pass thread quality. For best results, pair with the correct pre-hole diameter and maintain steady feeds to maximize surface finish and dimensional accuracy.
