Osg HP460-1250 Square End Mill 0.125in 3 Flute Tialn Carbide

Product Description

The OSG HP460-1250 is a solid carbide square end mill designed for high-performance material removal in demanding machining applications. With a 0.125 inch cutting diameter, 0.5 inch length of cut, and a 60-degree helix angle, this tool delivers aggressive chip evacuation and reduced cutting forces in tough workpiece materials. The TiAlN coating provides thermal resistance and wear protection, extending tool life in dry or semi-dry cutting conditions. Constructed from micrograin carbide, it maintains edge sharpness and dimensional accuracy through repeated use. This is a single-end, right-hand cut tool with spiral flutes and no chipbreaker.

The HP460-1250 is suited for milling steel, stainless steel, cast iron, high-temperature alloys, and hardened materials. Its 60-degree helix and TiAlN coating make it a strong fit for shops running difficult-to-machine alloys or hardened workpieces where standard end mills lose edge life quickly. Typical applications include profiling, slotting, and contouring on CNC machining centers and manual mills where a 0.125 inch diameter tool is required. It is centercutting, allowing plunge entry.

Key Features

• 0.125 inch cutting diameter with 0.5 inch length of cut for precise, controlled engagement
• 60-degree helix angle promotes efficient chip flow and reduced cutting force
• TiAlN coating for thermal resistance and extended tool life in hard and high-temp materials
• Micrograin solid carbide construction for rigidity and edge retention
• Centercutting geometry allows direct plunge entry
• Right-hand cut, right-hand flute with spiral flute configuration

Compatibility

Designed for use in CNC machining centers and manual milling machines accepting a 0.125 inch straight shank. Rated for primary workpiece materials including steel, stainless steel, cast iron, high-temperature alloys, and hardened materials per material codes P, M, K, S, and H.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Secure the shank in a collet or end mill holder to the full recommended grip depth to minimize runout. Verify tool projection and clearance before initiating a cut. Follow machine manufacturer guidelines and applicable shop safety procedures when working with carbide tooling.
