Seco 02409194 Milling Insert H15 Solid Carbide Uncoated

Product Description

The SECO 02409194 is a solid carbide, uncoated square milling insert in the SEEX-09 series, identified by ANSI and ISO code SEEX09T3AFN-E04. It carries a manufacturer grade of H15 using micrograin carbide construction. The insert measures 3/8 inches in length and width, with a thickness of 0.1563 inches and a 0.0118-inch corner radius. With a positive rake angle of 25 degrees and a sharp cutting edge style, it is engineered for efficient chip formation in non-ferrous metal machining. This insert is installed by machinists and tooling technicians on milling machines using compatible cutter bodies.

This insert is suited for milling non-ferrous metals such as aluminum, copper alloys, and similar workpiece materials where a sharp, uncoated cutting edge outperforms coated alternatives. The SEEX09T3AFN-E04 geometry delivers a positive 25-degree rake and a 20-degree relief angle, reducing cutting forces and heat buildup at the tool-workpiece interface. It fits compatible SECO cutter bodies in the R217.53-09 and R220.53-09 series. Applications span face milling, shoulder milling, and general milling operations in production and job-shop environments. Each package contains one insert; minimum order quantity is 10 units.

Key Features

• Solid carbide micrograin construction for consistent edge integrity on non-ferrous materials
• Bright/uncoated finish provides a sharp edge with low friction for aluminum and copper alloy milling
• Positive rake angle of 25 degrees and 20-degree relief angle reduce cutting forces
• 4 cutting edges per insert with neutral hand orientation for flexible setup
• E04 chip breaker geometry controls chip flow during high-feed non-ferrous passes
• Screw-held single-sided insert design for repeatable, secure seating in compatible cutter bodies

Compatibility

Compatible with SECO cutter series R217.53-09 and R220.53-09. ANSI and ISO code SEEX09T3AFN-E04 conforms to ISO standards for interchangeability verification. Designed for non-ferrous metal workpiece materials (Material Code N).

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the spindle before seating or removing inserts. Use the appropriate torx or hex key to secure the clamping screw to the cutter body per the cutter manufacturer torque specification; do not over-tighten, as this can fracture the carbide insert. Inspect the insert pocket and seating surfaces for chips or debris before installation to ensure proper insert contact and runout.
