Seco 17003169 Square End Mill 3/4 in 3 Flute Carbide

Product Description

The SECO 17003169 is a solid carbide square end mill designed for cutting aluminum and non-ferrous materials in milling operations. Built from micrograin carbide, it delivers the edge retention and dimensional stability required for precise material removal. The tool features a 45-degree helix angle and a bright uncoated finish, both suited to the low-friction, high-speed demands of non-ferrous machining. With a 3/4 inch cutting diameter and three flutes, it balances chip evacuation with rigidity. This is a single-end, centercutting tool, meaning it can plunge directly into the workpiece as well as perform peripheral milling. Machinists and CNC operators in production and job-shop environments are the primary installers of this tool.

This end mill is intended for use in milling machines and CNC machining centers where aluminum, brass, copper, and similar non-ferrous workpiece materials are processed. The short flute length classification and 1-5/8 inch length of cut make it appropriate for applications requiring stability and minimal deflection, particularly in shallow-to-moderate depth passes. The straight shank fits standard ER collet chucks, end mill holders, and similar toolholding systems common in horizontal and vertical machining setups.

Key Features

• Solid micrograin carbide construction for edge durability in non-ferrous applications
• 45-degree helix angle promotes efficient chip flow in aluminum and soft metals
• Centercutting design allows both plunge and peripheral milling operations
• Bright uncoated finish minimizes built-up edge on non-ferrous workpiece materials
• Right-hand cut and right-hand flute spiral for standard spindle rotation
• Tight tolerances: mill diameter -0.0000/-0.0020 inches, TIR maximum 0.0005 inches

Compatibility

Belongs to SECO Series A345 and is rated for primary workpiece material code N, covering aluminum and non-ferrous metals. Designed for use in standard straight-shank toolholders with a 3/4 inch bore. Coolant-through and extended-reach configurations are not applicable to this part number.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the machine placed in a locked-out, de-energized state per applicable lockout/tagout procedures. Secure the straight shank fully within the toolholder to the recommended engagement depth for the holder type in use; insufficient engagement is a common cause of tool pullout under load. Verify runout with a dial indicator before cutting; TIR for this tool is rated at a maximum of 0.0005 inches. Handle carbide tooling carefully to avoid chipping the cutting edges during setup.
