Sgs 00407 Square End Mill 0.04 in 4 Flute Solid Carbide

Product Description

The SGS 00407 is a solid carbide square end mill designed for precision milling of ferrous and non-ferrous materials in machine shop and toolroom environments. At 0.04 inches in diameter with a 0.06-inch length of cut, this is a micro end mill built for tight-tolerance work where tool rigidity and edge sharpness are critical. The micrograin carbide construction provides the hardness and wear resistance needed at small diameters. Four flutes with a 30-degree right-hand helix deliver efficient chip evacuation while maintaining a fine surface finish. Installed and run by machinists and CNC operators, this tool is suited for high-precision profiling and slotting passes in small-scale workpieces.

This end mill is appropriate for fine-detail milling operations on small components, mold cavities, and precision parts where a 0.04-inch diameter tool path is required. The bright, uncoated finish makes it a solid general-purpose choice across a range of base materials. The straight cylindrical shank at 0.125 inches fits standard collet systems used on vertical machining centers and CNC mills. The 1.5-inch overall length keeps the tool compact, reducing deflection at this diameter.

Key Features

• 0.04-inch mill diameter with a tight tolerance of +0.000 to -0.001 inches for precise dimensional control
• Micrograin solid carbide construction for edge strength and wear resistance at micro diameters
• Four-flute, right-hand spiral design with 30-degree helix for balanced chip flow
• Center-cutting capable, allowing direct plunge entry into the workpiece
• Bright/uncoated finish suitable for general-purpose milling across multiple material types
• Regular length classification with 0.06-inch LOC and 1.5-inch OAL for low-overhang setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills equipped with collet systems accepting a 0.125-inch straight cylindrical shank.

Installation Notes

Installation is performed by machinists or CNC operators. Ensure the machine spindle is fully powered down and locked out before tool changes. Seat the shank fully into the collet and torque the collet nut to the machine manufacturer's specification. At 0.04 inches diameter, this tool is highly susceptible to breakage from runout, misalignment, or aggressive feed rates — verify collet concentricity before operation.
