Osg 403-1181-BN Ball End Mill 3mm 3 Flute Solid Carbide

Product Description

The OSG 403-1181-BN is a single-end ball end mill from the 403BN series, designed for both roughing and finishing operations in metalworking applications. It features a 3.00 mm diameter, a 10.00 mm length of cut, and a 3-flute solid carbide construction. The 30-degree medium helix angle promotes efficient chip evacuation while maintaining surface finish quality. The bright uncoated finish makes it suitable for a range of workpiece materials. This tool is typically installed and operated by machinists and CNC programmers working in precision manufacturing environments.

This end mill is suited for milling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The 3.00 mm shank diameter matches the cutting diameter, allowing straightforward setup in standard collet chucks or end mill holders. With a 39.00 mm overall length and a 1.50 mm nose radius, it is appropriate for profiling, contouring, and slotting operations where a ball-nose geometry is required. The straight-cylindrical shank ensures consistent clamping in standard toolholding systems.

Key Features

Compatibility

Designed as an OEM-style replacement and standard tooling option for machining centers and CNC milling machines requiring a 3.00 mm ball end mill with a straight-cylindrical shank. Compatible workpiece material categories include steel (P), stainless steel (M), cast iron (K), non-ferrous metal (N), superalloys and titanium (S), and hard materials (H) per ISO material classification codes provided in the product data.

Installation Notes

This end mill should be installed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet or end mill holder bore size matches the 3.00 mm shank diameter before clamping. Do not exceed the tool manufacturer's recommended cutting parameters for the selected workpiece material and machine type.
