Osg 414-625011 Square End Mill 5/8 in 4 Flute Solid Carbide

Product Description

The OSG 414-625011 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. This stub-length, single-end tool features a 5/8 inch cutting diameter, a 3/4 inch length of cut, and a 3 inch overall length. The TiAlN coating provides heat and oxidation resistance, extending tool life in dry and semi-dry cutting conditions. The micrograin carbide substrate supports tight tolerances, with a mill diameter tolerance of +0.000/-0.001 inches and a shank diameter tolerance of +0.00000/-0.0005 inches. Installation and operation are handled by CNC machinists and manual mill operators in job shop, production, and tool room settings.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials where a rigid, compact tool is required. The stub-length geometry reduces overhang and improves rigidity compared to standard or long-reach configurations. The 30-degree helix angle promotes efficient chip evacuation during both climb and conventional milling passes. The centercutting design allows for plunge entry, adding flexibility to the tool path. It is part of the OSG Series 414 lineup.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiAlN finish for elevated heat resistance in dry and high-speed cutting
• 4 flutes with a 30-degree spiral helix angle for balanced chip evacuation
• Centercutting capability allows direct plunge milling
• Right-hand cut and right-hand flute configuration
• Stub length design improves stiffness and reduces deflection

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 5/8 inch straight shank, consistent with OSG Series 414 tooling specifications.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully into a collet or end mill holder rated for the shank diameter before operation. Verify spindle direction matches the right-hand cut specification before starting the machine. Inspect the cutting edges for chips or damage before each use and replace the tool if tolerances cannot be maintained.
