Kennametal 1712586 Milling Insert SPHX1205ZCERGP KC520M

Product Description

The KENNAMETAL 1712586 is a solid carbide milling insert carrying the ANSI and ISO designation SPHX1205ZCERGP in manufacturer grade KC520M. This double-sided, square-shaped insert features a TiAlN coating applied via PVD process, delivering hardness and thermal resistance suited for high-speed milling operations. With 8 cutting edges per insert, a positive rake angle of 30 degrees, and a honed cutting edge style, the 1712586 is engineered to reduce cutting forces and extend tool life in demanding milling applications. It is held in place by a screw-type clamping method and is compatible with Fix-Perfect cutter series toolholders.

This insert is designed for milling cast iron workpieces, corresponding to material grade K (C1, C2). It fits into face milling and shoulder milling applications in industrial machining environments, including production shops and job shops operating CNC machining centers. The GP chip breaker geometry supports reliable chip control across a range of depths of cut up to 0.3937 inches. The insert measures 0.2130 inches in length and 0.2170 inches thick, with an inscribed circle of 0.2165 inches (12.00 mm). Right-hand cutting orientation is standard.

Key Features

• Double-sided square insert with 8 usable cutting edges, maximizing cost-per-edge value
• TiAlN coating via PVD process for high thermal stability and wear resistance in cast iron milling
• Positive rake angle of 30 degrees reduces cutting forces and heat generation
• GP chip breaker geometry promotes consistent chip evacuation at varied feed rates
• Screw-held mounting compatible with Fix-Perfect cutter series toolholders
• Meets both ANSI and ISO standards under designation SPHX1205ZCERGP

Compatibility

Designed for use with Fix-Perfect cutter series toolholders. Carries ANSI and ISO insert code SPHX1205ZCERGP. Intended for right-hand cutting with a screw-type insert holding method.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the spindle before seating or replacing inserts. Use the correct torx or hex key to torque the clamping screw to the toolholder manufacturer specification — do not over-tighten, as this can fracture the carbide insert. Inspect the insert pocket seat for chips or debris before seating a new insert to ensure proper contact and runout.
