Seco 17003613 Square End Mill 1/2 in 5 Flute Solid Carbide

Product Description

The SECO 17003613 is a single-end square end mill designed for precision metal removal in demanding machining environments. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness and heat resistance needed when cutting steel, stainless steel, cast iron, high-temperature alloys, and hardened materials. The tool features a 0.5 inch cutting diameter, a 2 inch length of cut, and a 45-degree spiral flute helix angle that promotes chip evacuation and surface finish quality. It is installed and operated by machinists and CNC tool-and-die professionals running milling machines or machining centers.

This end mill is suited for high-performance milling applications across a broad range of workpiece materials including ferrous metals, non-ferrous metals such as aluminum, and hardened materials. Its centercutting geometry allows plunge entry, making it useful for slot milling, profiling, and pocket operations. The straight 0.5 inch shank fits standard ER and side-lock toolholders common in vertical and horizontal machining centers. The long-length configuration with a 4 inch overall length provides reach in deeper cavities where standard-length tools cannot access.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in tough materials
• AlTiN coating provides oxidation resistance and extended tool life at elevated cutting temperatures
• 45-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting design enables direct plunge entry for slot and pocket milling
• 5-flute configuration increases feed rate capability compared to 4-flute equivalents
• Right-hand cut, right-hand flute spiral with straight shank for broad toolholder compatibility

Compatibility

Part of the SECO Series S545 long-length end mill line. Designed for use in standard straight-shank toolholders with a 0.5 inch bore, compatible with ER collet chucks, milling chucks, and side-lock holders used on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Power down and lock out the spindle before loading or removing the tool. Ensure the shank is fully seated in the toolholder to the recommended gauge line before torquing the retention mechanism. Confirm runout does not exceed the maximum TIR of 0.0005 inches after tool mounting to avoid premature wear or tool failure.
