Kennametal 2598817 Grooving Insert NGP3125 KC5010 Carbide

Product Description

The KENNAMETAL 2598817 is a solid carbide grooving insert designed for precise external grooving and parting operations on CNC lathes and turning centers. Built to the NGP3125 insert style in the Top Notch series, this left-hand insert features a TiAlN coating applied via PVD process, delivering enhanced hardness and heat resistance at the cutting edge. The cutting width measures 0.125 inches (3.18 mm) with a maximum depth of cut of 0.150 inches (3.81 mm). The KC5010 grade targets a broad range of steel, stainless, and cast iron applications. Licensed machinists and CNC turning specialists are the primary installers and users of this insert.

This insert is suited for grooving and profiling operations in both production and job-shop turning environments. The positive rake geometry at 5 degrees and a lead angle of 3 degrees promote free cutting action and reduced cutting forces, making it effective in light-to-medium duty interrupted and continuous cut scenarios. The corner radius of 0.0075 inches (0.19 mm) supports fine-detail groove profiles. It is engineered for use in Top Notch series compatible toolholders that accept the NGP3125 insert form. This is a single-insert package sold in minimum order quantities of 5 units.

Key Features

• TiAlN PVD coating provides high surface hardness and oxidation resistance for extended tool life
• Solid carbide substrate in KC5010 grade - material grades C3 and C4 - suited for steel and cast iron workpieces
• Positive 5-degree rake angle reduces cutting forces and promotes chip flow
• Left-hand cutting orientation for specific toolholder and groove-face requirements
• 0.125-inch (3.18 mm) cutting width with a maximum depth of cut of 0.150 inches (3.81 mm)
• Corner radius of 0.0075 inches (0.19 mm) enables precise groove geometry control
• Top Notch series insert design for secure, repeatable seating in compatible toolholders

Compatibility

Designed for use in Top Notch series toolholders that accept the NGP3125 left-hand grooving insert form. Confirm toolholder seat geometry and insert size designation before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the turret is in a safe position before handling or changing inserts. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer - do not overtighten, as this can fracture the carbide insert. Verify insert seating and orientation before resuming cutting operations.
