Seco 17003626 Square End Mill 1 Inch 5 Flute Solid Carbide

Product Description

The SECO 17003626 is a single-end square end mill designed for high-performance milling in demanding metalworking applications. Built from micrograin solid carbide and finished with an AlTiN coating, this tool handles aggressive cuts in steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials. The 1 inch cutting diameter pairs with a 2-5/8 inch length of cut and a 45-degree helix angle for efficient chip evacuation and stable cutting action. Licensed machinists and CNC operators reach for this tool when working on production runs that demand tight tolerances and coating durability under heat.

This end mill fits standard 1 inch straight-shank toolholders and is suited for vertical machining centers, horizontal mills, and manual knee mills where a 6 inch overall length provides adequate reach without excessive overhang. Its centercutting geometry allows plunge entry, expanding the range of operations including slot milling, profiling, and pocket roughing. The S545 series is engineered for multi-material capability, making it a practical choice for job shops running varied workpiece materials across the ISO P, M, K, S, N, and H material groups.

Key Features

• Micrograin solid carbide substrate for rigidity and wear resistance
• AlTiN coating extends tool life in dry and semi-dry cutting conditions at elevated temperatures
• 5-flute geometry increases feed rates and surface finish quality compared to 4-flute designs
• 45-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting design supports plunge milling and full-slot entry
• Right-hand cut, right-hand spiral flute configuration for conventional CNC spindle use

Compatibility

Designed for use in standard 1 inch straight-shank toolholders on CNC and manual milling machines. Compatible with ISO material groups P, M, K, S, N, and H, covering steel, stainless steel, cast iron, high-temp alloys, aluminum and non-ferrous metals, and hardened materials.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Verify TIR does not exceed 0.0005 inches after mounting to maintain dimensional accuracy and tool life. Secure the shank to the minimum recommended engagement depth in the toolholder and confirm all axes are zeroed before initiating a cut. Power down the spindle and engage the machine lock before changing or inspecting the tool.
