Seco 17000104 Square End Mill 0.5 in 4 Flute Cvd Diamond Carbide

Product Description

The SECO 17000104 is a solid carbide square end mill engineered for high-performance cutting in carbon fiber reinforced polymer (CFRP) materials and similarly abrasive composites. It carries a CVD diamond coating that dramatically extends tool life in non-ferrous and composite applications where uncoated carbide wears rapidly. The cutter measures 0.5 inches in diameter with a 1.375-inch length of cut and a 4-inch overall length. Four right-hand spiral flutes at a 30-degree helix angle promote chip evacuation and reduce delamination risk during composite machining. This tool is installed and operated by CNC machinists and tooling professionals working in aerospace, automotive, and precision fabrication environments.

This end mill is suited for milling CFRP panels, laminates, and composite structural components where surface integrity and tight dimensional tolerances are required. The centercutting geometry allows plunge entry, giving the operator flexibility in toolpath programming. The long-series designation provides additional reach for deeper pockets or stepped features without requiring an extended-reach holder. The straight shank fits standard 0.5-inch collets and tool holders commonly found on vertical machining centers and CNC routers.

Key Features

• CVD diamond coating optimized for abrasion resistance in CFRP and composite materials
• Micrograin solid carbide substrate for rigidity and edge retention
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• 30-degree right-hand spiral flutes promote efficient chip evacuation in composite cuts
• Long-series length type extends reach to 4 inches OAL for deeper feature access
• Single-end construction with a straight 0.5-inch shank for direct collet mounting

Compatibility

Designed as an OEM-specification solid carbide square end mill in the SECO DIAL430 series, intended for use with standard 0.5-inch collet chucks and end mill holders on CNC machining centers and routers capable of the required spindle speeds for composite cutting.

Installation Notes

Installation and operation should be performed by a qualified CNC machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is properly cleaned before seating the shank in the collet to maintain the specified TIR. Secure the collet nut to the tool holder manufacturer torque specification using the appropriate spanner wrench. Verify runout does not exceed 0.0005 inches TIR before beginning a production cut, as excessive runout accelerates edge wear on diamond-coated tools and can cause composite delamination.
