Osg HP441-1562 Square End Mill 5/32 Inch 4 Flutes Carbide

Product Description

The OSG HP441-1562 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. With a 5/32-inch (0.1562-inch) cutting diameter and a 9/16-inch length of cut, this tool is built for precision slotting, profiling, and peripheral milling operations. The 4-flute geometry and 35-degree helix angle promote efficient chip evacuation and smooth cutting action. A TiAlN coating enhances heat resistance and tool life, making this end mill well suited for cutting hardened steels, stainless steels, and other difficult-to-machine alloys at elevated speeds. Machining professionals and CNC operators rely on this series for consistent, repeatable results in production environments.

The HP441-1562 is suited for use in CNC machining centers and manual milling machines handling precision work in ferrous and non-ferrous materials. Its 3/16-inch shank diameter and 2-inch overall length make it appropriate for tight-clearance applications and compact workholding setups. Right-hand cut and right-hand spiral flute configuration is standard for use with conventional spindle rotation. The centercutting design allows plunge milling where required, adding versatility to its application range.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-speed applications
• TiAlN coating improves heat resistance and extends tool life in ferrous materials
• 4-flute, 35-degree helix spiral design promotes chip flow and surface finish quality
• Centercutting capable - supports plunge entry without a pre-drilled pilot hole
• Right-hand cut, right-hand flute for standard spindle rotation compatibility
• Regular length profile suits general-purpose milling with minimal deflection

Compatibility

Designed as an OEM-style cutting tool in the OSG HP441 series, suited for use in CNC and manual milling applications requiring a 3/16-inch shank diameter tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank firmly in a collet or end mill holder rated for the shank diameter before operating. Verify spindle rotation direction matches the right-hand cut orientation before engaging the workpiece. Inspect the cutting edges for chips or damage before each use, and follow the machine tool manufacturer guidelines for speed and feed parameters appropriate to the workpiece material.
