The Carmex Thread Mills Carbide Mini Type is a precision, compact threading tool designed for engineers who need reliable internal and external threads in tight spaces. Built for UNJ forms (UNJC, UNJF, UNJEF, UNJS) with a 1/4" diameter and 28 TPI, it delivers consistent results across materials and applications.

• Diameter x pitch: 1/4" diameter with 28 TPI for small, precise thread milling in confined areas
• Thread forms supported: Works with UNJ family (UNJC, UNJF, UNJEF, UNJS) and can produce both internal and external threads with the same tool
• Shank: MT7 Morse taper shank ensures a rigid, accurate fit on compatible CNC machines
• Coating & carbide grade: Sub-micron MT7 carbide with Titanium Aluminium Nitride multi-layer coating (ISO K10–K20) for outstanding wear resistance
• Flute design: Spiral flutes with 3–5 cutting edges for smooth cutting action and efficient chip evacuation
• Coolant delivery: Through-flutes coolant enhances lubrication and cooling, ideal for deep-hole threading
• Machining speed: Optimized for medium to high cutting speeds to shorten cycle times and improve productivity
• Depth capability: Short profile and flute geometry enable effective deep-hole threading with reduced cutting forces
• Material versatility: General-purpose performance across materials, including hardened workpieces up to 45 HRC
• Durability: Triple-coated finish extends tool life for demanding production runs

This mini thread mill is built to simplify threading tasks in challenging environments—from molds and tooling to automotive and aerospace applications. By covering multiple UNJ pitches and both internal and external threads in a single tool, it reduces tool changes, lowers inventory, and delivers repeatable, high-precision threads. The combination of a robust MT7 shank, TiAlN coating, and coolant-through design translates to cleaner holes, fewer deflections, and longer tool life—even at higher speeds and with harder materials.
