Seco 03007670 Corner Radius End Mill 1 in 6 Flute Altin

Product Description

The SECO 03007670 is a solid carbide corner radius end mill built for demanding material removal in steel, stainless steel, cast iron, superalloys, and titanium. It carries a 1-inch mill diameter with a 0.2500-inch corner radius, a 2-inch length of cut, and a 5-inch overall length. The six-flute, right-hand spiral geometry runs at a medium helix angle of 38 degrees and is finished with an AlTiN (aluminum titanium nitride) PVD coating for heat resistance and extended tool life under aggressive cutting conditions. The micrograin carbide substrate supports both roughing and finishing operations in a single setup, making it a productive choice where tool changes need to be minimized.

This end mill is suited for CNC machining centers handling ferrous and exotic workpiece materials in job shop, aerospace, and general manufacturing environments. The centercutting design allows plunge entry, and the straight-cylindrical shank seats directly in standard toolholders. The close pitch and stub length classification make it especially effective in low-clearance setups where rigidity and chip control are priorities. Single-end configuration means the tool is replaced rather than re-indexed when worn.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating provides thermal barrier and oxidation resistance at elevated cutting speeds
• Six flutes with close pitch for high material removal rate and surface finish quality
• 0.2500-inch corner radius (tolerance plus or minus 0.00100 inch) reduces stress concentration at corners and extends part life
• Centercutting geometry supports plunge milling without a pre-drilled lead hole
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed for use with standard toolholders accepting a 1-inch straight-cylindrical shank. Primary workpiece material codes P, M, K, and S cover steel, stainless steel, cast iron, superalloys, and titanium. Part of the SECO S638R series.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and lock out the spindle before seating or removing the tool from the toolholder. Verify runout does not exceed the 0.0005-inch TIR maximum before beginning a cut. Follow the machine tool manufacturer and applicable shop safety guidelines for cutting speed, feed rate, and coolant selection appropriate to the workpiece material.
