Kennametal 6525753 Milling Insert KCPK30 Solid Carbide

Product Description

The KENNAMETAL 6525753 is a solid carbide milling insert in the LNGQ series, grade KCPK30, designed for indexable milling operations on a wide range of metallic workpiece materials. The insert features a CVD-applied multilayer coating of TiN, TiCN, and Al2O3, which provides thermal resistance and wear protection during interrupted and continuous cuts. With a rectangular shape, a 90-degree included angle, and a positive rake geometry, this insert promotes free cutting action and reduced cutting forces. It carries 4 usable cutting edges on a single-sided body, making it an efficient consumable for production milling environments. The ANSI and ISO code is LNGQ120608ERGEKT4, and the insert is compatible with the Mill 4-12 cutter series.

This insert is suited for milling steel, stainless steel, cast iron, superalloys, and titanium, covering material codes P, M, K, and S. It is intended for use in CNC milling centers and manual knee mills where an indexable carbide insert system is employed. The GE chip breaker geometry is optimized for controlling chips across these varied material groups. Right-hand cutting orientation makes it a standard fitment for the majority of LNGQ-style milling cutter bodies. Machinists and CNC operators in job shops, production facilities, and maintenance machining environments are the primary installers.

Key Features

• CVD multilayer coating: TiN, TiCN, and Al2O3 for thermal and wear resistance
• Solid carbide substrate in manufacturer grade KCPK30, material grade C1, C5, and C6
• 4 cutting edges per insert, single-sided body for indexed cost efficiency
• Positive rake angle with honed cutting edge style reduces cutting forces
• GE chip breaker for effective chip control across steel, stainless, cast iron, and superalloys
• Conforms to ANSI and ISO standards; catalog number LNGQ120608ERGEKT4

Compatibility

Compatible with Mill 4-12 cutter series bodies using the LNGQ insert style and size code 120608. Screw-held insert mounting method applies. ANSI and ISO code LNGQ120608ERGEKT4 can be used to cross-reference compatible cutter bodies from other sources listed in the input.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Ensure the cutter body is fully removed from the spindle and the machine is locked out before indexing or replacing inserts. Use the correct torx or hex key specified by the cutter body manufacturer to secure the clamping screw to the appropriate seating torque per cutter body documentation. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to prevent improper seating and premature edge failure.
