Seco 17002979 Square End Mill 1/2 in 2 Flute Solid Carbide

Product Description

The SECO 17002979 is a solid carbide square end mill designed for high-precision material removal in aluminum and non-ferrous applications. This single-end, center-cutting tool features a 0.5 inch mill diameter, a 3.125 inch length of cut, and a 6 inch overall length. Built from micrograin solid carbide substrate in an uncoated bright finish, it runs a 2-flute, right-hand spiral flute geometry at a 45-degree helix angle. That combination delivers efficient chip evacuation and clean surface finishes on soft metals. Licensed machinists and CNC operators working in job shops, production environments, and aerospace or automotive component manufacturing will find this tool appropriate for a wide range of milling operations.

The 17002979 belongs to SECO Series A245 and is optimized for cutting aluminum and other non-ferrous materials (ISO material code N). The straight shank measures 0.5 inches in diameter, making it compatible with standard ER or side-lock collet chucks. The regular-length classification and 3.125 inch length of cut support slotting, profiling, and pocketing operations in setups where extended reach is not required. This is a fractional-inch tooling system part suited for machine shops running both conventional and CNC milling equipment.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in non-ferrous materials
• 45-degree helix angle with 2 right-hand spiral flutes for efficient chip evacuation
• Center-cutting geometry allows plunge entry into the workpiece
• Bright uncoated finish optimized for aluminum and non-ferrous alloys
• Mill diameter tolerance of +0.0000 to -0.0020 inches for consistent dimensional accuracy
• Right-hand cut and right-hand flute direction; straight shank for broad chuck compatibility

Compatibility

Designed for use in standard 0.5 inch straight-shank collet or side-lock toolholders on vertical and horizontal milling machines. Primary workpiece material is aluminum and non-ferrous metals (ISO material code N).

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the holder. Verify runout does not exceed the specified TIR maximum of 0.0005 inches after tool mounting. Do not use this tool on ferrous materials, as the uncoated carbide substrate and flute geometry are optimized specifically for non-ferrous applications.
