Seco 17004602 Square End Mill 0.25 in 4 Flute Carbide Cvd

Product Description

The SECO 17004602 is a solid carbide square end mill engineered for high-performance cutting in composite and abrasive materials. With a 0.25 inch mill diameter, 1.375 inch length of cut, and 4-inch overall length, this tool is built for precision material removal in demanding applications. The CVD diamond coating significantly extends tool life when cutting carbon fiber reinforced polymers (CFRP) and similar abrasive workpiece materials. A 30-degree spiral flute geometry and micrograin carbide substrate combine to deliver clean edges and reduced delamination in composite machining. Installed by CNC machinists and tool and die professionals, this end mill is a single-end, centercutting design with right-hand cut and right-hand flute orientation.

This end mill is designed primarily for machining CFRP materials and other abrasive composites where standard coatings wear prematurely. The long-length configuration and straight shank make it well suited for setups requiring extended reach in milling fixtures and CNC machining centers. The centercutting capability allows for plunge entry where required. Part of the SECO DIAL430 series, this tool addresses production environments where tool life, surface finish, and dimensional accuracy are critical factors in composite part manufacturing.

Key Features

• CVD diamond coating optimized for CFRP and abrasive composite materials
• 4-flute, 30-degree spiral geometry for efficient chip evacuation and edge quality
• Centercutting design allows direct plunge entry
• Micrograin solid carbide substrate for rigidity and wear resistance
• Straight shank with tight shank diameter tolerance of -0.0001 to -0.0004 inches
• Series DIAL430 long-length configuration for extended reach applications

Compatibility

Designed as an OEM-style tooling solution for CNC machining centers and milling machines accepting a 0.25 inch straight shank, with primary application in CFRP and abrasive composite material cutting within the SECO DIAL430 series.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC toolholding systems. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the end mill. Use a properly sized collet or toolholder rated for 0.25 inch straight shanks and verify runout does not exceed the specified TIR maximum before running production. Follow the machine tool manufacturer guidelines for speeds, feeds, and clamping torque for carbide tooling in composite materials.
