Seco 17003161 Square End Mill 1/2 in 3 Flute Carbide

Product Description

The SECO 17003161 is a single-end, solid carbide square end mill designed for precision milling of aluminum and non-ferrous materials. It features a 1/2 inch cutting diameter, a 1-1/4 inch length of cut, and a 45-degree helix angle that promotes efficient chip evacuation and smooth cutting action in softer, gummy materials. The three-flute geometry balances rigidity and chip clearance, making it well-suited for slotting, profiling, and peripheral milling operations. The bright uncoated finish is standard for aluminum applications, avoiding the built-up edge issues that can occur with coated tools on non-ferrous stock. Machinists and CNC operators in job shops and production environments are the primary users of this tool.

This end mill is intended for use on CNC machining centers and manual mills where aluminum, copper, brass, and other non-ferrous workpiece materials are the primary stock. The 1/2 inch straight shank fits standard ER collet chucks, end mill holders, and shrink-fit tooling systems commonly found in production and prototype shops. Its single-end configuration makes it a standard replacement tool for high-run non-ferrous machining programs. The Series A345 designation places it within SECO's solid carbide end mill line for non-ferrous and general-purpose applications.

Key Features

• Solid carbide micrograin substrate for edge sharpness and wear resistance in non-ferrous materials
• 45-degree helix angle promotes aggressive chip evacuation and reduces cutting forces in aluminum
• Three-flute design balances chip clearance with core strength for slotting and profiling
• Bright uncoated finish eliminates coating adhesion issues common with aluminum and copper alloys
• Center-cutting geometry allows plunge entry in addition to peripheral and slot milling
• Right-hand cut and right-hand flute direction for standard spindle rotation

Compatibility

Designed as a direct-fit replacement for 1/2 inch straight-shank solid carbide end mills used in non-ferrous milling applications. Compatible with standard ER collet systems, end mill holders, and shrink-fit toolholders accepting a 1/2 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Clean the collet bore and shank contact surfaces before seating the tool to maintain runout within specification. Confirm that TIR does not exceed 0.0005 inches after installation to preserve tool life and surface finish quality.
