Meet the Korloy SDXT130508R-MM PC9530 — engineered for high productivity in milling operations.

Key Features & Specs

  • Geometry: 90° square insert (SDXT style), right-hand (R) orientation, with chipbreaker “MM” for general milling use.

  • Grade / Coating: PC9530 — PVD-coated carbide, optimized for good balance of toughness and wear resistance in general milling tasks. 

  • Dimensions / Indicators (per Korloy spec summary):
    • Insert thickness: ~0.218898 in (≈5.56 mm) 
    • Inscribed circle: ~0.531496 in (≈13.50 mm) 
    • Corner radius: ~0.031496 in (≈0.80 mm)

  • Cutting Applications: Primarily built for milling (face, side, peripheral milling) in a general machining role (interrupted or non-interrupted). 

  • Workpiece Suitability: Works well on steels (P), stainless (M), cast irons (K) in general to moderately demanding milling scenarios

Why It’s a Best Seller

  • Longer tool life & less downtime: The PVD coating on PC9530 gives superior wear resistance while retaining substrate toughness, making it durable in real shop conditions. 

  • Stable machining & better finishes: The chipbreaker and geometry design help maintain consistent chip control, reduce edge chipping, and yield improved surface quality on the workpiece.

  • Cost-efficiency per component: Because these inserts last longer and reduce unexpected tool changes, your effective cost per part drops — especially for high quantity runs.

  • Wide adoption: Trusted by machinists across sectors because it handles a broad range of materials without extreme specialization.

🏭 Application Industries

  • Automotive – milling engine blocks, brackets, gearbox components

  • Aerospace – structural parts, brackets, fixtures

  • Die & Mold – cavity milling, core machining, finishing passes

  • General Engineering / Job Shops – general milling on steel, cast iron, stainless, etc.

Frequently Asked Questions

It is ideal for general to medium milling on materials like steel (P class), stainless steel (M class), and cast iron (K class). Its PVD coating and substrate balance wear resistance and toughness for these material classes.

Yes — the square geometry and chipbreaker “MM” design allow it to resist chipping and maintain stability under moderately interrupted conditions. However, for extreme heavy-duty roughing or very high depths of cut, a more specialized grade or geometry may sometimes outperform it.

PC9530 offers a good balance between toughness and wear resistance, making it versatile. In Korloy’s grade lineup, it sits well for general and moderate milling tasks, rather than extremes (ultra high wear or ultra tough extremes)

The insert has a corner radius of ~0.031496 in (~0.80 mm) per manufacturer geometry data.
