Carmex Thread Mills Carbide Drill Mill - UN (UNC UNF UNEF UNS) - x 20 - MT7

The Carmex Thread Mills Carbide Drill Mill is a high-precision, all-in-one internal hole maker designed for high-volume production. It drills, chamfers, and thread mills UNC/UNF/UNEF/UNS threads in a single pass, delivering reliable performance on blind and through holes alike.

• All-in-one operation: Combines drilling, chamfering, and thread milling to reduce cycle times and eliminate tool changes on busy production lines.
• Two-fluted geometry: Optimized for smooth chip evacuation and stable cutting in challenging materials.
• 45° chamfer: Generates a precise entry chamfer that supports clean thread formation and consistent tolerances in mass production.
• Universal internal threads: Supports right- and left-hand internal threads across UNC, UNF, UNEF, and UNS standards.
• Blind and through-hole versatility: The same tool delivers high-quality threads whether the hole ends in a surface or continues through the part.
• Internal coolant bore: Delivers coolant directly to the cutting edge to control heat, extend tool life, and improve surface finish.
• MT7 Sub-Micron carbide with PVD triple coating: Combines exceptional hardness and toughness with a smooth, high-performance cutting surface for longer tool life.
• Precision thread quality: Designed to deliver consistent, high-quality thread surfaces for reliable assembly and function.

Designed for engineers and machinists focused on efficiency and quality, this tool helps you reduce cycle times without compromising thread integrity. Its robust carbide construction and advanced coating ensure durability in demanding applications, while the flexible threading options simplify setup and tooling inventory. Ideal for automotive, aerospace, hydraulic, and general precision manufacturing where reliable, repeatable internal threads are essential.
