Seco 17003619 Square End Mill 3/4 in 5 Flute Carbide Altin

Product Description

The SECO 17003619 is a single-end square end mill designed for high-performance milling across a wide range of metalworking applications. Built from micrograin solid carbide with an AlTiN coating, it delivers heat resistance and edge durability in demanding cutting environments. The tool features a 3/4-inch diameter, 1-inch length of cut, and a 45-degree spiral flute helix that promotes chip evacuation and cutting efficiency. With 5 flutes and a centercutting design, it handles both plunge and peripheral cutting operations. Licensed machinists and CNC tooling professionals install this end mill in vertical and horizontal milling setups across production and job shop environments.

This end mill is suited for milling steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials. The stub-length configuration and straight shank make it a practical choice for applications where rigidity and reduced deflection are priorities. Its right-hand cut and right-hand flute orientation are standard for conventional CNC and manual milling machines. No extended reach or coolant-through features are present, keeping setup straightforward for general-purpose contouring, slotting, and profiling operations.

Key Features

• Micrograin solid carbide construction for wear resistance and edge retention
• AlTiN coating provides thermal protection in high-speed and dry cutting applications
• 5-flute design increases feed rate potential compared to standard 4-flute geometry
• 45-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting capability allows direct plunge entry into workpiece material
• Stub-length body improves rigidity and minimizes deflection in tight setups

Compatibility

Designed as an OEM-style replacement or direct tooling selection for Series S545 solid carbide square end mill applications requiring a 3/4-inch diameter, 3/4-inch straight shank, and 1-inch length of cut.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. The machine spindle must be powered down and locked out before inserting or changing end mills. Use a calibrated tool holder and collet sized for a 3/4-inch straight shank, and verify runout does not exceed the 0.0005-inch TIR maximum. Follow the machine manufacturer's recommended clamping torque for the tool holder type in use.
