Tool-flo 563825RJ5R Grooving Insert GP3 Solid Carbide Tin

Product Description

The TOOL-FLO 563825RJ5R is a solid carbide grooving insert designed for precision external grooving and turning operations on CNC lathes and turning centers. Built to FLG3125 insert style specifications, this right-hand insert delivers a cutting width of 0.1252 inches (3.18 mm) and a maximum depth of cut of 0.1799 inches (4.57 mm). The micrograin carbide substrate is finished with a PVD-applied TiN coating under the GP3 manufacturer grade, providing wear resistance across a range of workpiece materials. Machinists and toolroom technicians working in production or job-shop environments are the primary users of this insert.

This insert fits within the Flo-Lock series toolholding system and is suited for applications requiring controlled groove geometry on lathes running ferrous and non-ferrous materials. The right-hand orientation governs its use in conventional right-hand cutting setups. With a positive rake angle of 55 degrees and a lead angle of 3 degrees, the insert is engineered for efficient chip control and reduced cutting forces in grooving operations. The gage diameter is 0.3750 inches (3/8 inch), and the overall width measures 0.1950 inches.

Key Features

• Solid micrograin carbide substrate for improved edge strength and wear life
• PVD TiN coating (GP3 grade) for surface hardness and oxidation resistance
• Cutting width of 0.1252 inches (3.18 mm) with a max depth of cut of 0.1799 inches (4.57 mm)
• Positive rake geometry at 55 degrees for reduced cutting forces
• Right-hand cutting orientation for standard CNC lathe setups
• ISO code FLG-3125R for cross-reference and toolholder matching

Compatibility

Designed for use with Flo-Lock series toolholders accepting FLG3125 insert style. ISO code FLG-3125R is the manufacturer cross-reference designation. The MSC/manufacturer number is listed as FLG-3125R/L.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or clamp screw driver specified for the toolholder to secure the insert without over-torquing the clamp mechanism. Verify insert orientation and hand designation match the toolholder before resuming cutting operations.
