Tungaloy 6804310 Turning Insert EPGT040102L-W08 Carbide

Product Description

The TUNGALOY 6804310 is a coated carbide turning insert with ISO designation EPGT040102L-W08, designed for precision metal cutting on CNC lathes and turning centers. It features a 75-degree diamond insert shape (shape code E), a left-hand cutting orientation, and a TiCNO coating applied via PVD process. The insert carries manufacturer grade GH110 and measures 4.10 mm in length with a 3.97 mm inscribed circle and a 0.20 mm corner radius. A positive rake angle of 15 degrees and a honed cutting edge style support clean, controlled cuts in finishing and semi-finishing operations. Screw clamping is the designated holding method.

This insert is suited for turning, facing, and boring operations in both residential shop and industrial production environments. It is optimized for cast iron and non-ferrous metals, corresponding to ISO material codes K and N, with material grades K10, K25, N05, and N15. The W08 chip breaker geometry supports light to moderate depths of cut up to 1.00 mm. Licensed machinists and CNC operators working in precision component manufacturing are the primary installers and users of this insert type.

Key Features

• TiCNO PVD coating on carbide substrate for wear resistance in cast iron and non-ferrous applications
• 75-degree diamond shape (EPGT style) with positive 15-degree rake for reduced cutting forces
• Left-hand cutting orientation with honed edge for consistent surface finish
• W08 chip breaker geometry supports turning, facing, and boring in a single insert
• Maximum depth of cut of 1.00 mm suits finishing and light semi-finishing passes
• Screw-on mounting via 2.30 mm hole diameter for secure, repeatable seating

Compatibility

Designed for use in toolholders and boring bars configured for EPGT-style inserts with a screw clamping method. Meets ANSI and ISO standards; industry standard number EPGT 520.5 L-W08. Verify toolholder pocket geometry and screw size before installation.

Installation Notes

Install and replace turning inserts with the machine fully powered down and the spindle locked. Use the correct Torx or hex key for the clamping screw and ensure the insert seats fully and evenly in the pocket before torquing. Inspect the insert pocket for chips or debris prior to seating a new insert, as contamination can affect runout and surface finish. Index or replace the insert when edge wear affects part tolerance or surface quality.
