Tool-flo 79125AAC3R Grooving Insert VDB125 AC3R Solid Carbide

Product Description

The TOOL-FLO 79125AAC3R is a solid carbide grooving insert in the Vee Bottom series, designed for precision grooving operations on ferrous workpiece materials including cast iron and steel. The insert carries grade AC3R with an AlTiN (aluminum titanium nitride) coating applied via PVD process, providing thermal resistance and wear protection in demanding cutting conditions. Cutting width is 0.125 inches (3.18 mm) with a cutting height of 0.250 inches and a corner radius of 0.015 inches. The double-end configuration maximizes usable tool life. It is sized to the VDB125 insert style and held in place by a clamp-type toolholder.

This insert is suited for grooving and profiling applications on CNC lathes and turning centers where cast iron or steel workpieces are machined. The Vee Bottom profile and neutral hand orientation make it applicable to both OD and face grooving setups depending on the compatible toolholder. Machinists and toolroom technicians running production or job-shop turning operations will find this insert appropriate for standard grooving depths within the VDB125 size range. ISO code VDB125A015 and catalog reference VDB 125 A015 are associated with this insert.

Key Features

• Solid carbide substrate with AlTiN PVD coating for extended wear resistance on steel and cast iron
• 0.125 inch (3.18 mm) cutting width with 0.015 inch corner radius for controlled groove geometry
• Double-end insert design for two usable cutting edges per insert
• Neutral hand orientation compatible with standard clamp-type VDB toolholders
• Vee Bottom series profile for positive seating and repeatable positioning in compatible seats
• AC3R grade optimized for primary workpiece materials of cast iron and steel

Compatibility

Designed for use in clamp-type toolholders accepting VDB125 series inserts with ISO code VDB125A015. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation and replacement of grooving inserts should be performed by a qualified machinist or toolroom technician with the machine powered down and in a locked-out, tagged-out state per applicable safety procedures. Seat and clamping surfaces should be clean and free of chips before seating the insert. Use the appropriate torque driver or clamping wrench specified by the toolholder manufacturer to avoid cracking the carbide substrate. Inspect the insert seat and clamp for wear at each index.
