Sgs 02903 Square End Mill 3mm 2 Flute Solid Carbide

Product Description

The SGS 02903 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 3 mm (0.1181 inches) mill diameter with a 0.1772-inch length of cut and a 1/8-inch straight cylindrical shank. The two-flute, right-hand cutting geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. An AlTiN coating provides thermal resistance and extended tool life in ferrous and hard alloy materials. Micrograin carbide construction delivers consistent edge integrity under demanding cutting conditions. This tool is suited for machinists and tool-and-die professionals working with CNC machining centers and manual mills.

The SGS 02903 is used in precision metalworking environments where small-diameter end milling is required. Its regular length classification and single-end design make it well suited for slotting, profiling, and peripheral milling operations in steel, stainless steel, cast iron, and similar materials. The centercutting capability allows plunge entry, expanding its utility in complex part programs. This end mill is a common choice for mold and die shops, aerospace component machining, and general CNC production work requiring tight tolerances at small diameters.

Key Features

• 3 mm (0.1181 inches) mill diameter with micrograin solid carbide construction for rigidity and edge retention
• AlTiN coating provides high-temperature resistance and reduced friction in ferrous cutting applications
• 30-degree helix angle with right-hand flute direction promotes efficient chip flow and reduced cutting forces
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• 1/8-inch straight cylindrical shank with h6 tolerance for precise tool holder fitment
• 50 mm (approximately 1.969 inches) overall length in a regular-length classification

Compatibility

Designed as an OEM-style replacement and standard production end mill compatible with CNC machining centers and manual mills accepting a 1/8-inch straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Use a calibrated tool holder and torque wrench appropriate for the shank diameter to secure the end mill without over-clamping, which can damage the shank or alter runout. Verify tool projection and runout with a dial indicator before initiating a cutting program.
