Tool-flo 563678PRAC3R Grooving Insert Flo-lock AC3

Product Description

The TOOL-FLO 563678PRAC3R is a solid carbide grooving insert designed for precision external grooving operations on CNC lathes and turning centers. It carries an AlTiN coating applied via PVD process, delivering thermal resistance and extended tool life in demanding cutting conditions. The insert features a 0.078 inch cutting width, a maximum depth of cut of 0.12 inches, and a neutral rake angle. It is designed for right-hand cutting orientation and uses a clamp-style holding method. Machinists and CNC operators working in production turning environments install this insert to achieve consistent groove geometry on small-diameter workpieces.

This insert is suited for grooving applications on cast iron, non-ferrous metals, and stainless steel. It belongs to the Flo-Lock series and is configured as a double-end insert, allowing for two usable cutting edges per insert body. The AC3 manufacturer grade and PVD AlTiN coating make it particularly effective in applications requiring clean surface finish and resistance to built-up edge. It is appropriate for both light production runs and higher-volume turned-part operations where insert geometry consistency is critical.

Key Features

• Solid carbide construction with PVD AlTiN coating for thermal and wear resistance
• 0.078 inch cutting width with a maximum depth of cut range of 0.10 to 0.15 inches
• Double-end design provides two usable cutting edges per insert
• Corner radius range of 0.005 to 0.010 inches for controlled groove edge definition
• Neutral rake angle suits a broad range of workpiece materials including stainless steel and cast iron
• Clamp-type insert holding method for secure seating in compatible Flo-Lock toolholders

Compatibility

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or changing inserts. Use a torque wrench appropriate for the clamp screw to avoid cracking the carbide body - refer to the toolholder manufacturer specifications for correct clamp torque. Verify insert seating and clamp engagement before resuming cuts.
