Seco 10008526 Square End Mill 5/32 in 4 Flute Carbide

Product Description

The SECO 10008526 is a single-end square end mill designed for precision milling in steel, cast iron, aluminum, and other non-ferrous materials. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed in demanding shop environments. The tool features a 30-degree variable helix geometry that reduces chatter and improves chip evacuation across a range of cutting conditions. With an HTA coating applied to the flute and cutting edge surfaces, the tool resists heat buildup during high-feed operations. Licensed machinists, tool-and-die technicians, and CNC operators typically specify this end mill for finishing and semi-finishing passes where tight tolerances are required.

This end mill is suited for both manual and CNC milling applications in job shops, maintenance machining, and production environments. The 5/32 inch diameter and 15/32 inch length of cut make it appropriate for slotting, profiling, and contouring in tighter workpiece features. It is part of the SECO STS430.2 series, which targets general-purpose milling across steel and non-ferrous workpiece materials. The 3/16 inch shank diameter fits standard collet and end mill holder configurations common in small-diameter tooling setups. The centercutting geometry allows plunge entry when the operation requires it.

Key Features

• Micrograin solid carbide construction for rigidity and extended edge life
• 30-degree variable helix reduces vibration and improves surface finish
• HTA coating provides thermal resistance during steel and cast iron milling
• Centercutting design permits plunge milling entry
• Right-hand cut and right-hand spiral flute configuration
• Single-end tool with standard length profile for general milling use

Compatibility

Part of the SECO STS430.2 series. Suitable for milling operations on steel, cast iron, aluminum, and non-ferrous workpiece materials as indicated by material codes P, K, and N. Fits standard 3/16 inch collets and end mill holders.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC operator with the spindle fully stopped and the machine in a locked-out state. Ensure the collet or end mill holder is clean and free of debris before seating the shank. Verify runout with a dial indicator after clamping, as excessive runout accelerates edge wear on small-diameter carbide tools. Follow the machine tool manufacturer's guidelines and applicable shop safety standards when setting speeds and feeds.
