Seco 17002340 Corner Radius End Mill 1/2 in 7 Flute Altin

Product Description

The SECO 17002340 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. It features a 1/2 inch cutting diameter, a 2 inch length of cut, and a 0.0300 inch corner radius that reduces stress concentrations at the cutting edge. Seven right-hand spiral flutes with a 38-degree helix angle and close pitch geometry support efficient chip evacuation. An AlTiN PVD coating provides thermal and abrasion resistance during high-speed cutting of ferrous and hard-to-machine materials. This tool is suited for CNC milling operations where both roughing and finishing passes are required in a single setup.

This end mill is built for machining steel, stainless steel, cast iron, superalloys, and titanium. Its long-length configuration, 4 inch overall length with a 1/2 inch straight cylindrical shank, allows access to deeper features and pockets while maintaining rigidity. It is a single-end tool intended for use in compatible toolholders on CNC machining centers. Machinists and tooling specialists working in precision manufacturing, aerospace, mold and die, and general metalworking will find this tool well suited to close-tolerance profiling and contouring work.

Key Features

• 7-flute, right-hand spiral design with close pitch for smooth cutting action and high surface finish quality
• AlTiN PVD coating rated for steel, stainless steel, cast iron, superalloys, and titanium (material codes P, M, K, S)
• 0.0300 inch corner radius reduces edge chipping and improves tool life at workpiece transitions
• 38-degree helix angle supports effective chip flow in long-reach and deep-pocket applications
• Micrograin solid carbide substrate provides rigidity and edge retention at elevated cutting temperatures
• Suitable for both roughing and finishing operations in a single tool

Compatibility

Designed for use with standard straight-bore toolholders accepting a 1/2 inch cylindrical shank. Part of the SECO S738R series of corner radius end mills for demanding multi-material machining environments.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the toolholder manufacturer's clamping specifications. Ensure the machine spindle is fully stopped and the tool is secured with appropriate runout verification before initiating a cut — maximum TIR for this tool is 0.0005 inches as specified. Confirm tool projection length and holder compatibility before mounting to avoid excessive overhang. Follow shop-standard feeds and speeds guidelines for the specific workpiece material when programming this tool.
