Dorian Tool 73310182227 Cutoff Grooving Insert SGTN3

Product Description

The DORIAN TOOL 73310182227 is a single-end solid carbide cutoff and grooving insert in the Slot-Grip series, designated grade DASK25B. It carries an SGTN3 insert style with a 3.1 mm (0.122 inch) cutting width, a neutral lead angle, and a 30-degree relief angle. The PVD-applied TiN and TiAlN dual coating supports performance across a broad range of workpiece materials. Machinists and CNC tool-room technicians use this insert for parting-off operations and external grooving on lathes and turning centers where precise slot width and repeatable seating are required.

This insert is suited for cut-off and grooving applications in both manual and CNC turning environments. Its universal primary workpiece material rating covers steel (P), stainless steel (M), cast iron (K), and high-temperature alloys (S), making it a versatile option for production shops running mixed-material work. The self-grip holding method locks the insert securely into compatible Slot-Grip toolholders without the need for additional clamping hardware, reducing setup time between cuts.

Installation Notes

This insert is installed and removed by a qualified machinist or toolroom technician; power down and lock out the machine spindle before changing inserts. Seat the insert fully into the Slot-Grip pocket and verify the self-grip retention is engaged before resuming the cut. Inspect the insert seat and pocket for chips or debris that could affect seating depth or width accuracy. Follow the machine manufacturer and toolholder manufacturer guidelines for feed, speed, and depth-of-cut recommendations appropriate to the workpiece material group.
