Osg 3056212 Ball End Mill 1mm 2 Flute Solid Carbide

Product Description

The OSG 3056212 is a 2-flute solid carbide ball end mill engineered for high-precision finishing operations on hard materials and high-hardness steels. It features a 1.00 mm cutting diameter with a 0.80 mm length of cut and a 0.50 mm nose radius, making it suited for fine detail work in tight geometries. The extended long-neck design provides reach into deep cavities without sacrificing rigidity. A DUROREY PVD coating improves wear resistance and thermal stability during cutting. This tool is used by machinists and tool-and-die professionals working on hardened steel components, mold cavities, and precision part finishing where tight tolerances and fine surface finishes are required.

The OSG 3056212 is designed for use on CNC machining centers running high-hardness steels and hard materials. The extended neck at 10.90 mm and a neck diameter of 0.95 mm allow the tool to reach into deep pockets and contoured surfaces. The straight-cylindrical shank with a 4.00 mm diameter fits standard ER and precision collet systems. This mill supports both roughing and finishing passes in a single tool, reducing changeover time in production environments.

Key Features

• 1.00 mm cutting diameter with 0.50 mm nose radius for fine detail and contour work
• DUROREY PVD coating rated for hard materials and high-hardness steel applications
• Extended long-neck design with 10.90 mm neck length and 0.95 mm neck diameter for deep-cavity reach
• 30-degree medium helix angle with right-hand spiral flutes for efficient chip evacuation
• Solid carbide construction delivers rigidity and dimensional stability at small diameters
• Single-end, straight-cylindrical shank compatible with standard precision collet systems

Compatibility

Designed for use in CNC machining applications on hard materials (H) and steel (P) workpieces. Part of OSG Series 8590, a line of high-precision finishing long-neck carbide ball end mills for high-hardness steels.

Installation Notes

Installation should be performed by a qualified machinist following machine tool manufacturer guidelines. Secure the straight-cylindrical shank in a precision collet or toolholder to the recommended clamping depth before operation. Verify runout at the tool tip prior to cutting, as small-diameter carbide tools are sensitive to collet condition and spindle health. Do not exceed the tool manufacturer's recommended speeds and feeds for the coating and workpiece material combination.
