Seco 17004711 Roughing End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The SECO 17004711 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from solid carbide with a TiCN coating, it delivers extended tool life and heat resistance in demanding cutting environments. The coarse-pitch, 3-flute spiral geometry with a right-hand cut and right-hand flute direction promotes efficient chip evacuation. Key dimensions are a 0.25 inch mill diameter, 0.75 inch length of cut, and 2.5 inch overall length. This tool is installed and run by machinists and CNC operators working in production and job-shop settings.

The 17004711 is suited for roughing passes on metals and hard materials where high material removal rate is the priority. The coarse pitch reduces chatter and helps clear chips at elevated feed rates. The 45-degree chamfer angle and 0.02 inch chamfer width contribute to controlled entry and edge stability. A maximum helix angle of 30 degrees balances cutting force and chip flow. The straight-cylindrical shank with a 0.25 inch diameter fits standard collets and end mill holders used in vertical and horizontal milling centers.

Key Features

• Solid carbide construction for rigidity and wear resistance
• TiCN coating improves surface hardness and thermal resistance
• 3-flute coarse-pitch design promotes chip clearance at high feed rates
• Right-hand cut and right-hand spiral flute direction
• Center-cutting capability allows plunge entry
• 45-degree chamfer angle with 0.02 inch chamfer width for controlled edge engagement

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide roughing end mill for standard 1/4 inch collets and end mill holders in vertical or horizontal milling machine setups.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state per applicable machine safety procedures. Verify collet or holder bore size matches the 0.25 inch straight-cylindrical shank before mounting. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material and coating type. Inspect the cutting edges for chips or wear before each use.
