Seco 03116006 Corner Radius End Mill 1/2 in 7 Flute Altin

Product Description

The SECO 03116006 is a solid carbide corner radius end mill engineered for high-demand material removal in steel, stainless steel, cast iron, and superalloys including titanium. It carries a 1/2 inch mill diameter, a 2 inch length of cut, and a 0.0300 inch corner radius ground to a tolerance of plus or minus 0.00100 inch. The 7-flute, close-pitch geometry is optimized for roughing operations where chip load and tool life are the primary concerns. An AlTiN PVD coating adds heat and wear resistance suited to dry or semi-dry cutting conditions. The tool weighs 0.35 pounds and is intended for use by machinists and CNC operators in production or job-shop environments.

This end mill is used in milling operations on ferrous and exotic materials where a corner radius profile is required to reduce stress concentration at the base of a cut. Its long-length configuration — 4 inch overall length with a 2 inch length of cut — supports deeper pocket and slot work where standard-reach tools cannot reach. The straight cylindrical 1/2 inch shank is compatible with standard ER collet chucks and hydraulic or shrink-fit toolholders. Right-hand cutting direction and right-hand flute spiral are standard orientation for conventional CNC milling centers.

Key Features

• 7-flute, close-pitch design for aggressive roughing and high metal removal rates
• AlTiN PVD coating provides elevated thermal resistance during dry and semi-dry cutting
• 0.0300 inch corner radius reduces tool and workpiece stress at cut boundaries
• Micrograin solid carbide substrate delivers rigidity and edge retention on hardened ferrous and superalloy workpieces
• Long series length (4 inch OAL, 2 inch LOC) enables deep pocket and slot milling applications
• 38 degree helix angle supports smooth chip evacuation in medium-helix style cutting
• Single-end configuration; chipbreaker geometry included for interrupted-cut stability

Compatibility

Designed for use with standard straight-cylindrical-bore toolholders including ER collet chucks, hydraulic chucks, and shrink-fit holders accepting a 1/2 inch shank. Rated for primary workpiece materials: Steel (P), Stainless Steel (M), Cast Iron (K), and Superalloys and Titanium (S) per ISO material classification. Part of the SECO SCS738R series.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Ensure the toolholder bore is clean and free of chips or burrs before seating the shank. Confirm runout against the TIR maximum of 0.0005 inch after clamping to protect edge integrity. This tool is not center-cutting and should not be plunged axially; use ramping or helical entry for pocket work.
