Sgs 00554 Square End Mill 0.045 in 4 Flute Solid Carbide

Product Description

The SGS 00554 is a square-end, solid carbide end mill designed for precision milling in tight-tolerance applications. It features a 0.045-inch cutting diameter, a 0.135-inch length of cut, and a 1/8-inch straight cylindrical shank, with an overall length of 1.5 inches. Manufactured from micrograin solid carbide, this tool delivers the rigidity and edge retention required for fine detail work in hardened materials, non-ferrous metals, and composites. The 4-flute geometry and 30-degree helix angle promote efficient chip evacuation and a smooth surface finish. Centercutting capability allows plunge entry directly into the workpiece.

This end mill is suited for CNC machining centers and manual mills where small-diameter, high-precision cuts are required. It is commonly used in die and mold work, micro-part manufacturing, and intricate contouring operations where a tight diameter tolerance is critical. The right-hand cut and right-hand spiral flute configuration is standard for conventional spindle setups. The uncoated finish makes it a straightforward choice for applications where coolant is used and coating is not required.

Key Features

• 0.045-inch cutting diameter with a tight tolerance of +0.0000 / -0.0008 inches
• 4-flute spiral design with a 30-degree helix angle for smooth chip flow
• Centercutting geometry allows direct plunge milling
• Micrograin solid carbide construction for edge retention and rigidity
• Right-hand cut, right-hand flute for standard spindle compatibility
• Straight cylindrical 1/8-inch shank fits common collet and end mill holder systems

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC and manual milling setups using 1/8-inch collets or end mill holders requiring a straight cylindrical shank. Part of the SGS Series 1810 regular-length end mill family.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before changing tooling. Secure the shank in a properly sized collet or end mill holder, torquing to the tool holder manufacturer's specification. At this diameter, runout control is critical — inspect the holder and collet for wear before use, and verify indicated runout before beginning a cut.
