Keo 932-000-048 Corner Rounding End Mill 4 Flute Hss Tin

Product Description

The KEO 932-000-048 is a single-end corner rounding end mill designed to produce consistent, radiused edges on machined workpieces. It is manufactured from high speed steel and carries a Titanium Nitride (TiN) coating that improves surface hardness and extends tool life under moderate cutting loads. The mill features a 1/16 inch radius, a 7/16 inch mill diameter, and a 3/8 inch shank diameter with four flutes and a right-hand cutting direction. It is suited for use in manual mills, knee mills, and CNC machining centers where edge-breaking and radius profiling are required. Machinists and toolroom operators are the primary installers and users of this tool.

This end mill is appropriate for edge rounding operations on a broad range of workpiece materials including cast iron, hardened steel, non-ferrous metals, non-metals, heat-resistant superalloys, and structural steels, as indicated by the material codes H, K, M, N, P, and S. It is well suited to both production environments and toolroom applications where a repeatable corner radius is required. The 0-degree helix angle and four-flute configuration support stable engagement on edge-profiling passes.

Key Features

• 1/16 inch corner radius with a tight tolerance of plus 0.001 to minus 0.001 inches for consistent edge profiles
• 7/16 inch mill diameter (0.4375 inches) with a mill diameter tolerance of plus 0.002 to minus 0.000 inches
• 3/8 inch shank diameter for compatibility with standard collets and end mill holders
• High speed steel construction with Titanium Nitride coating for improved wear resistance
• Four-flute, single-end design with right-hand cutting direction and 0-degree helix angle
• 1/4 inch tip diameter (0.2500 inches) for clearance at the base of the radius

Compatibility

Designed for use with standard 3/8 inch collets and end mill holders on manual milling machines and CNC machining centers. Compatible workpiece material codes include H, K, M, N, P, and S.

Installation Notes

Installation of end mills should be performed by a qualified machinist. Ensure the spindle is fully powered down and locked out before inserting or removing the tool from the holder. The shank should be seated to the full recommended depth in the collet or holder, and the collet nut should be torqued using the appropriate spanner wrenches per the machine manufacturer specifications. Inspect the TiN coating and cutting edges for chips or wear before each use.
