Seco 17007033 Corner Radius End Mill 0.5in 5 Flute Altin

Product Description

The SECO 17007033 is a solid carbide corner radius end mill engineered for high-performance finishing operations in demanding materials. It features a 0.5-inch diameter, a 0.0200-inch corner radius, and five right-hand spiral flutes with a high-helix geometry at 45 degrees. The cutting surfaces are coated with AlTiN via a PVD process, providing thermal resistance and extended tool life when machining steel, stainless steel, superalloys, titanium, and hard materials. At 3 inches overall length with a 1.25-inch length of cut, this single-end, centercutting tool handles both plunge and peripheral milling. It belongs to the S545R series and is intended for use in standard toolholders with a straight cylindrical shank.

This end mill is suited for finishing passes on ferrous and exotic alloys in CNC machining centers across job shop, aerospace, and general manufacturing environments. Its AlTiN coating and solid carbide substrate make it particularly effective in dry or minimal-coolant cutting conditions at elevated speeds. The S545R series is designed for applications where tight tolerances and smooth surface finishes are required on steel and high-temperature alloys. Licensed machinists and CNC programmers working in production or toolroom environments are the primary users of this tool.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• AlTiN (PVD) coating provides oxidation resistance and extended tool life in high-heat cutting applications
• 0.0200-inch corner radius protects the cutting edge and reduces stress concentration at the tool tip
• Five-flute, high-helix design at 45 degrees improves chip evacuation and surface finish in finishing operations
• Centercutting geometry allows direct plunge entry into workpiece material
• Right-hand cut, right-hand flute spiral with normal pitch and straight cylindrical shank for broad toolholder compatibility

Compatibility

Designed for use with standard straight-bore toolholders accepting a 0.5-inch shank diameter. Suitable for CNC machining of steel, stainless steel, superalloys, titanium, and hard materials as identified by material codes P, M, S, and H. Part of the SECO S545R series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the toolholder bore is clean and within tolerance before seating the shank, as the shank diameter tolerance is tight (-0.0001 to -0.0004 inches). Confirm runout does not exceed the specified TIR maximum of 0.0005 inches after installation. Power down and lock out the spindle before tool changes, and verify all clamping torque specifications per the toolholder manufacturer guidelines.
