Osg 482-3150 Square End Mill 0.315 in 2 Flute Solid Carbide

Product Description

The OSG 482-3150 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. It features a 0.315 inch (8.00 mm) mill diameter, a 1.6535 inch (42.00 mm) length of cut, and a 2-flute spiral configuration with a 30-degree helix angle. Manufactured from micrograin carbide, it delivers the edge retention and rigidity required for demanding cutting tasks. The right-hand cut and right-hand flute orientation follow standard CNC and manual milling conventions. Its centercutting capability allows direct plunge entry without a pre-drilled pilot hole.

This end mill is suited for machining operations on ferrous and non-ferrous materials where an extra-long length of cut is needed to reach deep features, slots, or pockets. The 0.315 inch diameter and 2-flute geometry make it appropriate for slotting, profiling, and side milling in both production and job-shop environments. The overall length of 102.00 mm (approximately 4.016 inches) and 8.00 mm shank diameter allow direct installation in standard collets and end mill holders. Machinists, CNC operators, and toolroom technicians are the primary users of this tool.

Key Features

• 0.315 inch (8.00 mm) mill diameter with matching 8.00 mm shank diameter
• 1.6535 inch (42.00 mm) length of cut — classified as extra long for deep-feature access
• 2-flute spiral design with 30-degree helix angle for balanced chip evacuation
• Centercutting geometry allows direct plunge milling without a pilot hole
• Micrograin solid carbide construction for improved wear resistance and edge stability
• Uncoated finish — right-hand cut, right-hand flute, Series 482

Compatibility

Designed as an OEM-style tooling solution for standard end mill holders, ER collet chucks, and milling machine spindles accepting an 8.00 mm shank diameter, consistent with OSG Series 482 tooling specifications.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following the machine tool manufacturer's recommended toolholding procedures. Ensure the spindle is fully stopped and locked out before inserting or removing the end mill. Verify shank runout and tool projection length prior to cutting. Follow applicable shop safety standards and machine guarding requirements during operation.
