Tool-flo 79125AJ5R Grooving Insert VDB125 GP3R Carbide

Product Description

The TOOL-FLO 79125AJ5R is a solid carbide grooving insert designed for precision turning and grooving operations on CNC lathes and turning centers. Built to the VDB125 insert style with a GP3R manufacturer grade, this insert features a TiN (titanium nitride) coating applied via PVD process, delivering improved wear resistance and extended tool life. The cutting width measures 0.125 inches (3.18 mm), and the neutral hand orientation suits both left-hand and right-hand grooving setups. Micrograin carbide construction provides the edge integrity required for consistent, repeatable cuts in demanding production environments.

This insert is suited for grooving and turning operations in job shop and production machining environments, primarily on steel and cast iron workpieces. The Vee Bottom (VDB) series seating geometry ensures positive, repeatable insert positioning in compatible toolholders, making it a reliable choice for high-volume turning applications where consistent groove width and depth are critical. The clamp-style holding method keeps the insert securely locked under interrupted cuts and side loading conditions.

Key Features

• TiN coating via PVD process for reduced friction and extended tool life
• 0.125 inch (3.18 mm) cutting width for precise groove sizing
• Neutral hand orientation compatible with left-hand and right-hand toolholders
• Vee Bottom (VDB) seating geometry for repeatable, positive insert location
• Clamp-style holding method for secure retention under cutting loads
• Rated for steel and cast iron workpiece materials

Compatibility

Designed for use in VDB-style clamp-type grooving toolholders compatible with the 125 insert size series. ISO code VDB125A015. Suitable for machining steel and cast iron workpieces.

Installation Notes

Installation is performed by a machinist or toolroom technician on a powered-down, locked-out machine tool. Ensure the toolholder pocket and clamping surfaces are clean and free of chips before seating the insert. Follow the toolholder manufacturer's clamping torque specifications for the specific clamp style. Never exceed the insert's rated cutting parameters for depth of cut and feed rate.
