Seco 17004985 Square End Mill 1/32 Inch 4 Flute Carbide

Product Description

The SECO 17004985 is a single-end square end mill designed for precision machining of carbon fiber reinforced polymer (CFRP) and similarly abrasive composite materials. Manufactured from micrograin solid carbide and coated with a CVD diamond finish, this tool is engineered to withstand the extreme abrasiveness that destroys uncoated carbide quickly. The cutting diameter is 0.0313 inches (1/32 inch) with a length of cut of 0.0938 inches (3/32 inch), making it suitable for fine-detail slotting, profiling, and plunge operations where tight tolerances are required. It belongs to the SECO DIA430 series and is installed by machining professionals working on CNC milling equipment.

This end mill is intended for use in high-precision CNC milling applications involving CFRP panels, composite laminates, and other hard, abrasive non-metallic workpiece materials. The centercutting geometry allows direct plunge entry, expanding its utility in complex toolpath operations. With a 1/8 inch straight-cylindrical shank and a 1-1/2 inch overall length, it fits standard collet chucks used in vertical and horizontal machining centers. The regular-length classification and 30-degree helix angle make it a practical choice for finishing passes and tight-tolerance work in composite fabrication shops and aerospace component manufacturing environments.

Key Features

• CVD diamond coating engineered for extended tool life in abrasive CFRP and composite materials
• Micrograin solid carbide substrate for rigidity and edge retention at small diameters
• 4-flute spiral configuration with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand flute geometry compatible with standard CNC spindle rotation
• Mill diameter tolerance of -0.001/+0.001 inches and maximum TIR of 0.0002 inches for consistent precision

Compatibility

Designed for use with CNC milling machines equipped with 1/8 inch collets or collet chucks. Primary workpiece material designation is CFRP (material code C), covering carbon fiber reinforced polymers and similarly abrasive composite laminates. Part of the SECO DIA430 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before loading or changing the tool. Seat the 1/8 inch straight-cylindrical shank fully into a clean, undamaged collet and tighten to the chuck manufacturer's specification. At this diameter, runout control is critical — verify TIR at the cutting edge before beginning production cuts.
