SPMG110408R XP9130

The SPMG110408R XP9130 is a heavy-duty square insert with an 11.5mm inscribed circle. It is specifically engineered for large-scale drilling where stability and chip evacuation are the primary challenges. Paired with the XP9130 PVD grade, this insert provides the ultimate solution for drilling large holes in Stainless Steel and Heat-Resistant Alloys without compromising tool life.

Key Features:

• Grade XP9130 (PVD Coated): A high-performance grade with a specialized PVD coating layer. It is the industry standard for Stainless Steel (M) and High-Temperature Alloys (S), offering exceptional resistance to built-up edge and thermal cracking in deep-hole applications.

• Chipbreaker Geometry: The design is critical at this size. It curls the wide, thick chips produced by larger drills into manageable coils, ensuring they are flushed out by internal coolant and preventing "chip bird-nesting" inside the hole.

• 0.8mm Nose Radius: Provides maximum reinforcement to the cutting corner. This ensures the insert can survive the high-impact entry into raw material and maintain its geometry through long, high-feed production runs.

• 11mm Series Stability: With a thickness of 4.76mm and a wide seating area, this insert offers the structural rigidity needed for high-penetration rates in large-diameter drilling (typically for drills above 42mm).

• Best For:

  • Heavy-Duty Drilling: Fits large U-Drill bodies (generally 42mm to 55mm+ diameter).

  • Challenging Materials: Excellent for 304, 316, 316L, and Duplex Stainless Steels.

  • Oil & Gas / Heavy Engineering: Ideal for drilling large flanges, valve bodies, and thick structural components.
