Osg HP441-1562-BN Ball End Mill 0.1563 in 4 Flute Carbide

Product Description

The OSG HP441-1562-BN is a solid carbide ball end mill from the HP441BN Hy-Pro-Carb series, engineered for extended tool life in demanding machining applications. It carries a 0.1563-inch mill diameter and a 4-flute helical configuration with a 35-degree helix angle, supporting both roughing and finishing operations. The TiAlN PVD coating adds thermal resistance and wear protection at elevated cutting speeds. The submicron carbide grade provides the toughness and edge retention needed when working harder materials. Licensed machinists and CNC operators install this tool in vertical and horizontal machining centers requiring a small-diameter ball profile.

This end mill is suited for work in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The single-end, straight-cylindrical shank design fits standard collet and end mill holders. With no chipbreaker, no coolant-through, and no extended reach, it is built as a standard-length tool for close-tolerance contouring, 3D profiling, and finish passes in tight pockets where a ball nose geometry is required. It cuts right-hand with a right-hand flute direction.

Key Features

• Solid carbide submicron grade construction for edge retention in hard and abrasive materials
• TiAlN PVD coating for thermal resistance and extended tool life
• 4-flute helical design at 35-degree helix angle supports both roughing and finishing passes
• Ball nose profile with 0.0782-inch nose radius for accurate 3D contouring
• Single-end, straight-cylindrical shank with h6 shank diameter tolerance for consistent runout in precision holders
• Part of the HP441BN Hy-Pro-Carb series, designed as a performance upgrade over standard carbide end mills

Compatibility

Rated for use in steel (P), stainless steel (M), cast iron (K), superalloys and titanium (S), and hard materials (H) per ISO workpiece material codes. Fits standard 3/16-inch collet and end mill holders with a straight-cylindrical shank.

Installation Notes

Installation is performed by a CNC machinist or toolroom technician. The machine spindle must be brought to a full stop and the tool path program verified before mounting this end mill in a collet or shrink-fit holder. Verify holder runout with a dial indicator before cutting to protect the small-diameter cutting edge. Follow the machine manufacturer and OSG series guidelines for feeds, speeds, and depth of cut when engaging hard or exotic materials.
