Kennametal 1998336 Grooving Insert G300E KD1405 Diamond

Product Description

The KENNAMETAL 1998336 is a diamond-tipped grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Built to the G300E style in the A4 series, this insert carries the KD1405 manufacturer grade with a CVD coating process and a bright, uncoated finish. It delivers a 3.00 mm (0.1181 inch) cutting width and a maximum depth of cut of 3.50 mm (0.1378 inch). The insert is neutral-hand, meaning it can be used in standard right-hand or left-hand toolholders depending on the setup. It is installed by machinists and toolroom technicians working with hard or abrasive workpiece materials where diamond-tipped tooling is required.

This insert is suited for grooving and parting applications on materials that demand the wear resistance of diamond-tipped tooling, such as high-silicon aluminum alloys, metal matrix composites, graphite, and other non-ferrous or highly abrasive materials. The neutral hand orientation makes it adaptable across a range of A4-series grooving toolholders. Its compact insert size (300) and defined chip breaker geometry (E) make it appropriate for controlled-depth grooving passes within the 3.00 mm to 4.00 mm maximum depth of cut range.

Compatibility

Designed for use in A4-series grooving toolholders accepting G-style inserts at the 300 insert size designation. Verify toolholder specifications against insert geometry before installation.

Installation Notes

Diamond-tipped grooving inserts are installed by qualified machinists or toolroom personnel. Power down and lock out the machine before changing inserts. Use the correct torque wrench and clamping hardware specified by the toolholder manufacturer — do not overtighten or undertighten the clamping screw, as either condition can cause insert movement or fracture. Diamond-tipped tooling is brittle; avoid interrupted cuts or impact loads unless the insert is rated for such applications.
