Tool-flo 6334189LN4C Grooving Insert GP50 Carbide Tin

Product Description

The TOOL-FLO 6334189LN4C is a solid carbide grooving insert in the Flo-Lock series, designed for precision grooving and parting operations on CNC lathes and turning centers. This left-hand insert carries a GP50 carbide grade and a PVD-applied TiN coating, which improves surface hardness and wear resistance. It delivers a cutting width of 0.189 inches with a maximum depth of cut of 0.25 inches and is held in place by a clamp-style insert holding method. The insert style is FLGD3189L and suits applications where accurate groove geometry and consistent tool life are required. Machinists and CNC operators in production and job-shop environments install this type of insert.

This insert is suited for grooving operations on steel workpieces in both production turning and job-shop environments. The Flo-Lock series is designed for secure clamping and repeatable positioning in compatible toolholders. The left-hand orientation targets specific spindle rotation and toolholder configurations. With a cutting height of 0.344 inches and a gage diameter of 0.375 inches, this insert fits standard Flo-Lock style pockets. The corner radius falls in the range of 0.020 to 0.025 inches, which suits general-purpose groove profiles where a small radius blend is acceptable.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before seating or replacing an insert. Use the appropriate clamping screw torque as specified by the toolholder manufacturer documentation. Inspect the pocket seat for chips or debris before seating the insert to ensure proper contact and prevent premature edge failure.
