Dorian Tool 73310182223 Cutoff Grooving Insert SGTN2

Product Description

The DORIAN TOOL 73310182223 is a solid carbide cutoff and grooving insert in the Slot-Grip series, designated insert style SGTN with a size code of 2 and manufacturer grade DASK25B. It carries a cutting width of 2.21 mm (0.0870 inches) with a neutral lead angle and 0-degree lead angle geometry, making it suited for straight plunge cuts and consistent groove profiles. The insert uses a self-grip holding method and features a PVD-applied TiN/TiAlN/TiN multilayer coating for wear resistance across a broad range of workpiece materials. Licensed machinists and toolroom technicians install this insert in compatible Slot-Grip toolholders.

This insert is rated for universal primary workpiece material compatibility, covering workpiece material codes K, M, P, and S - corresponding to cast iron, stainless steel, steel, and heat-resistant superalloys. Typical applications include cutoff operations and external grooving on CNC turning centers and manual lathes in both production and job-shop environments. The single-end configuration, 30-degree relief angle, and non-full-radius geometry suit precision groove profiles where dimensional accuracy and consistent width tolerance are required.

Key Features

• Solid carbide substrate with PVD TiN/TiAlN/TiN multilayer coating for extended tool life
• 2.21 mm (0.0870 inch) cutting width with a width tolerance of 0.0040 inches
• Neutral lead angle and 0-degree lead angle geometry for straight plunge cutoff and grooving
• 30-degree relief angle supports clearance in tight groove applications
• Self-grip insert holding method - no additional clamping hardware required
• Universal material code compatibility (K, M, P, S) for use across common workpiece materials

Compatibility

Designed for use in Slot-Grip series toolholders that accept SGTN style, size 2 cutoff and grooving inserts. Verify toolholder seat geometry and insert size code before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine powered down and spindle locked. Use the appropriate insert removal tool or seating wedge recommended for Slot-Grip holders - do not pry inserts with screwdrivers or unrated tools. Inspect the toolholder pocket for wear or debris before seating the new insert. Follow the machine manufacturer and toolholder manufacturer guidelines for feed rate and depth-of-cut limits when setting up for cutoff operations.
