Nikcole Mini-systems GIE7GW55LC6 Threading Insert C6

Product Description

The NIKCOLE MINI-SYSTEMS GIE7GW55LC6 is a carbide threading insert designed for precision thread-cutting operations on both internal and external thread profiles. Built to C6 carbide grade specifications, this insert features a 55-degree included angle, making it suitable for Whitworth, BSP, and other 55-degree thread form applications. The insert style is GIE and belongs to the Mini System series, which is engineered for smaller-diameter threading work where toolholder clearance and insert geometry are critical. Machinists and toolroom operators install this insert in compatible Mini System threading toolholders for use on CNC lathes and manual turning centers.

This insert is used in metalworking and precision machining environments where both internal and external 55-degree threads must be cut to close tolerances. The GIE style and Mini System series designation indicate fitment in compact threading applications, including small-bore internal threading where standard insert sizes cannot be used. It is appropriate for production shops, job shops, and toolroom setups running ferrous and non-ferrous materials that fall within the cutting capability of C6 carbide grade.

Key Features

• C6 carbide grade for general-purpose threading on a range of workpiece materials
• 55-degree included angle covers Whitworth and BSP thread form profiles
• Cuts both internal and external thread forms with a single insert style
• Corner radius of 0.0040 inches (maximum 0.0050 inches) for controlled thread root geometry
• Mini System series design for compact toolholder compatibility in tight-clearance applications
• GIE insert style provides consistent seating and repeatable indexing in compatible holders

Compatibility

Designed for use with NIKCOLE Mini System series threading toolholders that accept the GIE insert style. Confirm toolholder insert pocket specifications before ordering.

Installation Notes

Threading inserts should be installed and indexed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing or seating inserts. Use the correct torque wrench and insert clamping hardware specified by the toolholder manufacturer - do not overtighten the clamping screw, as carbide inserts can fracture under uneven clamping force. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper contact and alignment.
