Carmex 30I14UNMT7 Carbide Thread Mill Insert Un 14 Tpi

Product Description

The CARMEX 30I14UNMT7 is a solid carbide thread milling insert designed for cutting internal UN-standard threads at 14 teeth per inch. Manufactured from submicron carbide and coated with TiAlN for heat resistance and extended tool life, this insert carries the MT7 manufacturer grade designation, indicating suitability for demanding threading applications in production environments. The non-conical geometry of the 30I insert style maintains consistent thread form in through-hole and blind-hole configurations. At 0.217 inches thick, the insert seats rigidly in compatible thread mill toolholders. Installation is performed by machinists and tooling specialists on CNC milling centers equipped for thread milling cycles.

This insert is engineered for internal UN thread milling operations on CNC machining centers. The UN thread standard covers the full range of Unified National thread forms used widely in North American manufacturing. The 14 TPI pitch targets medium-coarse threading work common in general machining, aerospace component production, and industrial equipment repair. The TiAlN coating performs well in dry and semi-dry cutting conditions and extends insert life when threading ferrous and hardened materials. This item ships with a minimum order quantity of 5 inserts, with a package quantity of 1.

Key Features

• Submicron carbide substrate for high hardness and wear resistance
• TiAlN coating provides thermal barrier for dry and semi-dry threading
• MT7 grade designation suited for demanding production threading
• Internal thread geometry in UN standard at 14 TPI
• Non-conical insert form maintains consistent thread profile
• 0.217 inch thickness for stable seating in compatible toolholders

Compatibility

Designed as an OEM-style replacement or direct-use insert for thread milling toolholders accepting the 30I insert style. Confirm toolholder compatibility by matching insert style, thickness, and thread pitch specifications before installation.

Installation Notes

Thread mill inserts are installed and changed by qualified machinists or tooling technicians. Power down and lock out the CNC spindle before seating or replacing inserts. Use the correct insert clamp screw torque as specified by the toolholder manufacturer - do not overtighten. Verify CNC thread milling cycle parameters match the 14 TPI pitch before initiating a cut.
