Walter 6169109 Indexable Drill Insert P48448E57 WKP35S

Product Description

The WALTER 6169109 is a solid carbide indexable drill insert engineered for high-performance drilling in cast iron and steel applications. Part of the Tiger Tec series, it carries the WKP35S manufacturer grade and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for extended tool life and thermal resistance. The insert is square in shape with four cutting edges, an inscribed circle of 0.307 inches (7.8 mm), a thickness of 0.132 inches, and a corner radius of 0.019 inches (0.48 mm). It is designed for indexable drill toolholders used by machinists and toolroom professionals in production and job-shop environments.

This insert is suited for drilling operations in residential and commercial machining applications where cast iron and steel are the primary workpiece materials. The E57 chipbreaker geometry controls chip flow during deep-hole and through-hole drilling cycles. The square SNMG-style geometry allows four usable cutting edges before replacement, reducing per-hole tooling cost on high-volume runs. Typical applications include component drilling on CNC machining centers and drill press setups where consistent hole quality and tool life are critical.

Key Features

• Tiger Tec CVD coating (TiCN, Al2O3, TiN) for heat resistance and flank wear reduction
• Four cutting edges per insert for maximum edge utilization
• E57 chipbreaker optimized for cast iron and steel chip control
• Square insert shape with 90-degree included angle for stable seating
• WKP35S grade rated for both P35 steel and K35 cast iron material groups
• Meets ANSI and ISO standards; ISO Code P4841P-4R-E57 WKP35S

Compatibility

Designed for use with indexable drill toolholders accepting insert size code 48 square inserts conforming to ANSI and ISO standards; verify holder geometry and pocket dimensions before installation.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist with the spindle locked out and all machine power isolated per facility lockout/tagout procedures. Use a torque wrench appropriate for the toolholder clamp screw to avoid over-torquing the insert seat. Inspect the insert pocket and clamping components for wear or debris before seating a new insert. Follow the toolholder manufacturer's recommended clamping torque specification for insert size 48 square inserts.
