Walter 7170615 Milling Insert LNGX130708R-L55 WKP35G

Product Description

The WALTER 7170615 is an LNGX-series solid carbide milling insert in grade WKP35G, designed for face and shoulder milling operations on steel and cast iron workpieces. The insert features a CVD-applied TiAlN and TiN coating over a solid carbide substrate, delivering wear resistance and thermal stability at elevated cutting speeds. Key specs include a 13.70 mm length, 11.00 mm width, and 7.74 mm thickness with a 0.80 mm corner radius. The double-sided, 4-cutting-edge design extends tool life between index cycles. This insert is installed and indexed by qualified machining technicians in production and job-shop environments.

The LNGX130708R-L55 insert is suited for milling steel and cast iron in both roughing and semi-finishing applications. The L55 chip breaker geometry and negative rake angle at 28 degrees support stable cutting with controlled chip formation. The right-hand cutting configuration and chamfered, honed edge preparation make this insert appropriate for productive cuts at a maximum depth of cut of 13.70 mm. It is compatible with WALTER cutter series F2010 and F4041, making it a direct-fit choice for shops already running those tooling platforms.

Compatibility

Confirmed compatible with WALTER cutter series F2010 and F4041. ANSI and ISO code: LNGX130708R-L55 WKP35G. Material grades P35 and K35 cover primary workpiece materials of steel and cast iron.

Installation Notes

Installation and indexing should be performed by qualified machining personnel with the spindle powered down and locked out before handling inserts. Use the manufacturer-specified torx or hex key to seat the clamping screw to proper engagement without over-torquing the carbide body. Inspect the insert pocket and seating surface for chips or debris before indexing to a fresh cutting edge. Dispose of worn inserts per applicable facility waste procedures for carbide tooling.
