Sandvik Coromant 6334848 Ball End Mill 5/32 in 4 Flute Carbide

Product Description

The SANDVIK COROMANT 6334848 is a solid carbide ball end mill designed for precision milling of steel, stainless steel, cast iron, superalloys, and titanium. With a 5/32 inch (0.1563 inch) cutting diameter and a 4-flute spiral geometry, this single-end tool delivers both roughing and finishing capability in a compact form factor. The 30-degree medium helix angle promotes smooth chip evacuation and stable cutting across a range of workpiece materials. A bright/uncoated finish makes this mill suitable for general-purpose metal removal where coating buildup or added cost is a concern. Licensed machinists and CNC operators working in job shops or production environments will find this tool appropriate for contour milling, profiling, and slot work in harder materials.

This end mill is suited for CNC machining centers and manual mills where a small-diameter ball nose profile is required. The 5/16 inch length of cut and 3 inch overall length make it a standard-reach tool for pocketing and 3D contouring in confined features. It is part of the SANDVIK COROMANT Series 1B240, catalog number 1B2400397XA1630. The straight-cylindrical 1/4 inch shank fits standard ER or end mill collet holders common in production and toolroom setups. Primary workpiece material classifications covered are P (steel), M (stainless steel), K (cast iron), and S (superalloys and titanium).

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and exotic alloy applications
• 4-flute spiral geometry supports both roughing and finishing passes
• 30-degree medium helix angle for efficient chip evacuation
• Ball nose profile with 0.0782 inch nose radius enables 3D contouring and profiled surface work
• Bright/uncoated finish — no coating delamination risk in interrupted cuts or thin-wall features
• Mill diameter tolerance h9 and shank diameter tolerance h6 for consistent tool-to-holder fit

Compatibility

Designed as a standard-reach OEM-style solid carbide ball end mill in the SANDVIK COROMANT Series 1B240 line, compatible with ER collet chucks and straight-bore end mill holders accepting a 1/4 inch straight-cylindrical shank. Suitable for machining steel, stainless steel, cast iron, superalloys, and titanium workpieces.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling and runout specifications. Secure the shank fully within the collet or holder to the recommended grip length before torquing. Verify spindle runout at the cutting tip before commencing cuts to protect the carbide substrate from premature chipping. Do not use this tool beyond its rated length of cut or with excessive overhang, as carbide is brittle and sensitive to lateral deflection.
