Osg HP460-1000 Square End Mill 1 in 3 Flute Solid Carbide

Product Description

The OSG HP460-1000 is a solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. It features a 1.0000-inch cutting diameter, a 1.5-inch length of cut, and a 60-degree helix angle that promotes aggressive chip evacuation and reduced cutting forces. The TiAlN coating adds heat resistance and extends tool life in demanding applications. With three flutes and a right-hand spiral configuration, this end mill delivers a balance of chip clearance and surface finish. It is a single-end tool intended for use in CNC machining centers and manual mills operated by skilled machinists and toolroom professionals.

The HP460-1000 is part of OSG's HP456 series, engineered for high-speed and high-efficiency milling operations. It is suited for profiling, slotting, and peripheral milling in applications where tool rigidity and edge retention are critical. The 1-inch shank diameter and 4-inch overall length make it a practical choice for moderate-depth milling tasks in production and toolroom environments. Micrograin carbide construction supports use in hardened steels and other demanding workpiece materials.

Key Features

• 1.0000-inch cutting diameter with 1.5-inch length of cut for controlled depth engagement
• 60-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• TiAlN coating provides high-temperature resistance and extended tool life
• Micrograin solid carbide construction delivers rigidity and edge retention
• Right-hand cut, right-hand flute, spiral flute geometry for standard CNC and manual mill use
• Center-cutting capable, allowing plunge entry into workpiece material

Compatibility

Part of the OSG HP456 series. Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 1-inch shank diameter end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist familiar with tool holding systems and speeds and feeds for carbide end mills. Ensure the spindle is fully stopped and machine is powered down before changing tooling. Seat the shank fully in the collet or end mill holder to the recommended engagement depth and torque to the tool holder specification. Verify runout with a dial indicator before commencing cuts to protect edge integrity.
