Kennametal 5980819 Grooving Cutoff Toolholder 3mm Rh

Product Description

The KENNAMETAL 5980819 is an indexable grooving and cutoff toolholder built for external turning operations on CNC lathes and turning centers. It belongs to the Beyond Evolution series and uses a clamp-style insert holding method with EVSC-T toolholder geometry. The holder accepts EG0300M03P02 inserts and delivers a fixed groove width of 3 mm with a maximum depth of cut of 16 mm (0.63 inches). Through-coolant capability directs fluid directly to the cutting zone, supporting chip control and tool life in demanding grooving applications. This is a right-hand configuration intended for licensed machinists and toolroom professionals.

This toolholder is suited for external grooving and cutoff operations in production turning environments, including aerospace, automotive, and general metalworking shops. The 3/4 x 3/4 inch shank fits standard toolholding blocks and quick-change turrets commonly found on mid-size CNC lathes. The through-coolant feature makes it well-suited for interrupted cuts, deep grooving passes, and materials that generate stringy chips or high heat at the cutting edge. It is designed for use where consistent groove geometry and insert repeatability are required across multiple parts.

Key Features

• Fixed 3 mm groove width for consistent, repeatable grooving and parting operations
• Maximum depth of cut of 16 mm (0.63 inches) for deep grooving and cutoff applications
• Through-coolant design delivers coolant directly to the insert cutting edge

• Right-hand orientation for standard external turning setups
• 3/4 x 3/4 inch shank cross-section fits common toolholding systems
• Beyond Evolution series engineering for tight tolerance grooving

Compatibility

Compatible with EG0300M03P02 inserts. Insert seat size is 3.0. Mount size is 1212. Designed as an OEM-style fit for CNC turning centers and lathes equipped with 3/4 inch square shank toolholding.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Shut down the machine spindle and confirm all axes are at rest before changing inserts or mounting the toolholder. Verify shank clamp torque using the machine builder or toolholder manufacturer specifications, and confirm through-coolant port alignment with the turret supply before running coolant. Follow the machine tool builder guidelines and applicable shop safety standards when setting tool offsets after installation.
