Seco 17002765 Square End Mill 0.04 in 4 Flute Solid Carbide

Product Description

The SECO 17002765 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. With a 0.04 inch cutting diameter, a 0.0625 inch length of cut, and a 1/8 inch straight shank, this stub-length tool is built for rigidity and accuracy in tight-tolerance work. The micrograin carbide substrate provides wear resistance when cutting hard and abrasive materials. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation and surface finish quality. The bright uncoated finish makes it suitable for applications where coating interaction with the workpiece material is a concern. Licensed machinists and CNC operators are the primary installers and users of this tool.

This end mill is suited for milling operations on cast iron, stainless steel, aluminum and non-ferrous metals, steel, and high-temperature alloys. The centercutting geometry allows for plunge entry as well as conventional peripheral milling. The stub length-of-cut range, rated up to 0.1000 inches, makes it appropriate for shallow pocketing, slotting, and profiling passes where tool deflection must be minimized. It is part of the SECO MES430 series, which targets small-diameter precision work in CNC machining centers and manual mills.

Key Features

• 0.04 inch cutting diameter with a mill diameter tolerance of plus or minus 0.0005 inches for tight-tolerance work
• Micrograin solid carbide construction for hardness and edge retention in ferrous and non-ferrous materials
• Four right-hand spiral flutes at a 30-degree helix angle for efficient chip flow
• Centercutting design enables both plunge and peripheral cutting operations
• Bright uncoated finish compatible with a broad range of workpiece materials including aluminum, steel, stainless steel, cast iron, and high-temp alloys
• Stub length profile maximizes rigidity and minimizes deflection at small diameters

Compatibility

Designed for use in CNC machining centers and manual milling machines accepting a 1/8 inch straight shank. Part of the SECO MES430 series for small-diameter precision end milling applications across material groups K, M, N, P, and S per ISO workpiece material classification.

Installation Notes

This tool is installed by machinists and CNC operators using an appropriate collet or end mill holder sized for a 1/8 inch shank. Ensure the spindle and any power feeds are fully stopped and locked out before changing tooling. Verify runout does not exceed the specified TIR maximum of 0.0002 inches after seating the tool in the holder, as excessive runout will accelerate edge wear at this diameter. Do not exceed the recommended depth-of-cut range for the stub flute length.
