Osg 7814038 Milling Insert XP3035 Solid Carbide Zdkt

Product Description

The OSG 7814038 is a solid carbide milling insert in the ZDKT parallelogram style, designed for indexable milling operations in metalworking applications. Manufactured to grade XP3035 with a TiAlN PVD coating, this insert delivers wear resistance and thermal stability during high-speed cutting. It measures 3.80 mm (0.1496 inches) thick and 6.80 mm (0.2677 inches) in inscribed circle diameter, with a 2.00 mm corner radius and a maximum depth of cut of 0.0827 inches. The insert features a positive rake geometry with chamfered and honed cutting edges, a 15-degree relief angle, and a GM chip breaker. It is single-sided with 2 cutting edges and is held in the cutter body by a screw. Licensed machinists and CNC operators are the primary installers of this insert.

This insert is rated for primary use on steel (P-code workpiece material) and is also suitable for stainless steel and cast iron (M and K code materials). It fits the OSG 78PSE cutter series and is identified by ANSI and ISO code ZDKT11T320SR-GM. Typical applications include face milling and shoulder milling in production machining environments, both light-duty and medium-duty cuts on ferrous materials. The right-hand cutting orientation and positive rake geometry make it well suited for setups requiring reduced cutting forces on workpieces prone to deflection or work hardening.

Key Features

• Solid carbide substrate with TiAlN PVD coating for heat and wear resistance
• XP3035 manufacturer grade optimized for steel, stainless steel, and cast iron
• Positive rake geometry with chamfered and honed cutting edges reduces cutting forces
• GM chip breaker promotes controlled chip evacuation across a range of feed rates
• ZDKT11T320SR-GM ANSI and ISO designation ensures cross-reference accuracy
• Screw-lock insert holding method for secure, repeatable indexing

Compatibility

Designed for use with the OSG 78PSE cutter series. ANSI and ISO code ZDKT11T320SR-GM confirms fitment for toolholders specifying that insert designation.

Installation Notes

Insert replacement is performed by qualified machinists or CNC tooling technicians. Disengage and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer when tightening the clamping screw — do not overtighten, as this can fracture the carbide substrate. Inspect the insert pocket and seating surface for chips or debris before seating a new insert.
