Seco 74068311 Milling Insert OFER070405N-M10 F30M Carbide

Product Description

The SECO 74068311 is a solid carbide milling insert with manufacturer part number OFER070405N-M10, grade F30M, designed for use in indexable face milling and shoulder milling applications. The insert features an octagonal shape with 8 cutting edges, a TiAlN plus TiN PVD coating applied for wear resistance and extended tool life across demanding materials. The inscribed circle measures 0.7063 inches, thickness is 0.1795 inches, and maximum depth of cut is 0.2756 inches. The neutral rake angle and honed cutting edge style make this insert suited for stable, consistent material removal in production machining environments. Licensed machinists and CNC tooling technicians are the primary installers.

This insert is designed for universal material applications with a primary classification of H, K, M, N, and P material codes. Secondary workpiece materials include steel, stainless steel, cast iron, and hard materials. The M10 chip breaker geometry supports reliable chip control across these material groups. It is compatible with the SECO R220.43-07 cutter series and follows the OFER-07 series insert standard. The insert is single-sided, uses a wedge clamp holding method, and is manufactured to ISO standards. Typical use cases include production milling on CNC machining centers where consistent insert geometry and coating durability are required.

Key Features

• Octagonal insert shape with 8 cutting edges for maximum index count per insert
• TiAlN plus TiN PVD coating for heat and wear resistance across multiple workpiece materials
• M10 chip breaker geometry for controlled chip formation in steel, stainless steel, cast iron, and hard materials
• Neutral rake and neutral hand orientation for flexible toolpath compatibility
• Honed cutting edge style promotes edge stability and reduces micro-chipping
• Compatible with SECO R220.43-07 cutter series per manufacturer specification

Compatibility

Designed for use with the SECO R220.43-07 cutter series. Compatible with OFER-07 series insert seats. Suitable for primary workpiece material codes H, K, M, N, and P covering steel, stainless steel, cast iron, and hard materials per ISO classification.

Installation Notes

Insert seating and indexing should be performed by a qualified CNC tooling technician or machinist. Ensure the cutter body is fully de-energized and the spindle is locked before removing or indexing inserts. Use the appropriate torx or hex key specified by the cutter body manufacturer to engage the wedge clamp to the correct seating torque. Inspect the insert pocket for chips or debris before seating a new or indexed insert to ensure proper contact and prevent premature edge failure.
