Sgs 00534 Square End Mill 0.025 in 4 Flute Solid Carbide

Product Description

The SGS 00534 is a square end mill engineered for precision micro-milling applications in solid carbide construction. With a 0.025-inch cutting diameter and 4-flute spiral geometry, it delivers clean, stable cuts in ferrous and non-ferrous materials. The micrograin carbide substrate provides the hardness and wear resistance needed at small diameters where edge integrity is critical. A 30-degree helix angle balances chip evacuation with cutting force, and the centercutting design allows plunge entry into the workpiece. This tool is sized for CNC machining centers and high-speed spindles where tight tolerances and fine surface finishes are the standard requirement.

This end mill is suited for slotting, profiling, and pocket milling operations in die and mold work, aerospace components, medical device parts, and precision instrument manufacturing. The 0.075-inch length of cut keeps the flutes engaged over a controlled axial depth, reducing deflection at this small diameter. The 1/8-inch straight cylindrical shank fits standard collet systems commonly found on CNC mills and high-speed routers. It is a single-end, right-hand cut and right-hand flute tool in the SGS Series 1810 lineup.

Key Features

• 0.025-inch cutting diameter with a mill diameter tolerance of +0.0000 / -0.0008 inches for consistent sizing
• 4-flute spiral design with a 30-degree helix angle for balanced chip flow and surface finish
• Centercutting geometry allows direct plunge cuts without pre-drilling
• Micrograin solid carbide construction for hardness and edge retention at micro-scale diameters
• Right-hand cut and right-hand flute configuration — compatible with standard CNC spindle rotation
• Uncoated finish suitable for applications where coating thickness would affect dimensional accuracy at this diameter

Compatibility

Designed for use in standard 1/8-inch collet systems on CNC machining centers, high-speed mills, and precision routing equipment. Part of the SGS Series 1810 regular-length square end mill family.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and locked before changing tooling. Seat the shank fully into the collet to the recommended engagement depth before tightening to prevent runout at this small diameter. At 0.025 inches, even minor collet contamination or insufficient engagement can cause tool deflection or breakage — clean the collet bore before mounting.
