Seco 02941943 Corner Radius End Mill 0.5in 2 Flute Altin Carbide

Product Description

The SECO 02941943 is a solid carbide corner radius end mill designed for demanding metal removal in professional machining environments. Featuring a 0.5-inch diameter, a 2.5-inch length of cut, and a 0.010-inch corner radius, this single-end tool is built for both roughing and finishing passes on ferrous and non-ferrous materials. The AlTiN (aluminum titanium nitride) PVD coating improves heat resistance and extends tool life in high-temperature cutting conditions. With a 40-degree high helix angle and a 2-flute configuration, the 02941943 promotes efficient chip evacuation and reduced cutting forces across a wide range of workpiece materials.

This end mill is suited for use on CNC machining centers and manual mills where tight tolerances and surface finish quality are required on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The centercutting design allows for plunge entry, expanding its versatility in complex toolpaths. The straight-cylindrical shank fits standard toolholders and collet chucks. It is a strong candidate for shops handling aerospace, toolroom, and general metalworking applications that demand consistent performance across multiple material types and cut conditions.

Key Features

• 0.010-inch corner radius with tolerance of plus 0.00100 to minus 0.00100 inches for controlled edge protection and part blending
• AlTiN PVD coating provides elevated thermal and oxidation resistance for extended tool life in difficult-to-machine alloys
• 40-degree high helix angle promotes smooth chip flow and reduced heat buildup at the cutting edge
• Centercutting geometry allows direct plunge milling without a pre-drilled entry hole
• Micrograin solid carbide substrate delivers rigidity and wear resistance for both roughing and finishing operations
• Right-hand cut and right-hand flute spiral optimized for conventional CNC milling setups

Compatibility

Designed for use with standard straight-bore toolholders and collet chucks accepting a 0.5-inch shank. Suitable for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces. Part of the SECO NS240R series.

Installation Notes

Installation is performed by a machinist or toolroom professional. Ensure the toolholder bore and collet are clean and free of debris before seating the shank to achieve maximum runout accuracy. The TIR maximum for this tool is 0.0005 inches — verify runout at setup to maintain that specification. Follow machine tool manufacturer guidelines and applicable shop safety procedures when securing and indicating end mills.
