Carmex C18D60MT7 Threading Insert Carbide 60 Degree

Product Description

The CARMEX C18D60MT7 is a solid carbide threading insert designed for both internal and external thread cutting operations on CNC lathes and turning centers. It carries the MT7 manufacturer grade with a submicron carbide substrate and a coated finish for extended wear resistance. The included angle is 60 degrees, making it compatible with ISO and UN thread standards. The insert handles external pitches from 1.75 to 2.50 mm and 15 to 10 TPI, and internal pitches from 2.00 to 3.00 mm and 13 to 8 TPI. This is a size 18 insert style C18 D60, suitable for left-hand and right-hand cutting. Installation and use should be performed by qualified machinists or CNC tooling professionals.

This threading insert is used in precision thread-turning applications across both internal and external profiles. It is suited for production environments where consistent thread form on ISO-standard or UN-standard fastener profiles is required. Typical applications include threading on steel, aluminum, and similar machinable materials using CNC turning equipment. The bidirectional hand designation allows flexibility in programming left-hand or right-hand thread passes on the same insert style.

Installation Notes

This insert should be installed and replaced by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Use the correct torx or clamping screw specified for the toolholder to ensure proper insert seating. Verify thread pitch and hand selection in the CNC program before the first threading pass.
