Seco 10023145 Corner Radius End Mill 3/8 in 3 Flute Carbide

Product Description

The SECO 10023145 is a solid carbide corner radius end mill designed for precision milling of non-ferrous metals. It measures 3/8 inch in diameter with a 0.0300-inch corner radius and a 3/4-inch length of cut. The 5-inch overall length and 3-inch extended reach make this an extra-long tool suited for deep-pocket and extended-reach applications where standard-length end mills cannot access the workpiece. Three flutes with a 45-degree high helix angle and coarse pitch geometry support both roughing and finishing operations in a single setup. The ANF PVD coating is applied to extend tool life and reduce built-up edge when cutting aluminum, brass, copper, and similar non-ferrous workpiece materials.

This end mill is intended for use in CNC machining centers and manual milling machines where extended reach into cavities, slots, or profiled features is required. The centercutting design allows plunge entry directly into the workpiece. The straight-cylindrical shank seats in standard toolholders. Right-hand flute direction and right-hand cutting direction are consistent with conventional CNC spindle configurations. It is well suited for mold, die, and general precision machining work in non-ferrous materials where corner radius blending is specified on the part print.

Key Features

• 0.0300-inch corner radius blends sharp transitions and reduces stress concentrations at milled corners
• Solid carbide construction provides rigidity and dimensional stability at extended reach lengths
• ANF PVD coating optimized for non-ferrous metal cutting, resisting built-up edge
• 3-inch extended reach with 0.3600-inch neck diameter for deep-cavity access
• Centercutting geometry allows direct plunge milling without a pre-drilled entry hole
• Coarse pitch, high-helix spiral flutes support both roughing and finishing passes

Compatibility

Designed for use with standard straight-bore toolholders accepting a 3/8-inch cylindrical shank. Intended for milling non-ferrous metals including aluminum and copper alloys. Part of the SECO AN345R series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the full recommended engagement depth in the toolholder and verify runout does not exceed the specified maximum TIR before cutting. Do not use this tool on ferrous materials; it is rated for non-ferrous workpiece materials only.
