Product Description
The SECO 17002986 is a solid carbide square end mill designed for high-performance milling in aluminum and non-ferrous materials. It features a 3/4 inch cutting diameter, a 2-1/4 inch length of cut, and a 5 inch overall length. The tool runs a 45-degree helix angle with two right-hand spiral flutes and a right-hand cut direction, making it well-suited for efficient chip evacuation in softer, gummy materials. Built from micrograin carbide and left uncoated in a bright finish, this single-end centercutting tool handles both peripheral and plunge cuts. Machinists and CNC operators in job shops, aerospace shops, and production environments use this tool for slotting, profiling, and pocketing operations.
The 17002986 belongs to SECO Series A245 and is optimized for primary workpiece materials classified as aluminum and non-ferrous (ISO material code N). The straight 3/4 inch shank fits standard ER, side-lock, and shrink-fit toolholders commonly found on vertical machining centers and CNC mills. The centercutting geometry allows direct plunge entry without a pre-drilled start hole, adding flexibility in pocketing and cavity work. The bright, uncoated surface finish suits applications where coating buildup or heat transfer to the tool is a concern, particularly in high-speed aluminum finishing passes.
Key Features
- Solid micrograin carbide construction for rigidity and wear resistance in non-ferrous cutting
- 45-degree helix angle promotes aggressive chip evacuation and smooth cutting action in aluminum
- Centercutting design allows direct plunge milling without a starter hole
- Bright/uncoated finish suited for aluminum and non-ferrous where coating adhesion is undesirable
- Right-hand cut, right-hand flute configuration for standard spindle rotation
- Single-end geometry with a 2-1/4 inch length of cut and 5 inch overall length for extended reach applications
Compatibility
Designed as an OEM-style replacement or direct-application tool for CNC machining centers and manual mills using standard 3/4 inch straight-shank toolholders. Primary workpiece materials are aluminum and non-ferrous metals per ISO material code N.
Installation Notes
Installation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout/tagout state before loading or changing tooling. Seat the straight shank fully into the toolholder to the minimum insertion depth recommended by the holder manufacturer, and verify runout with a dial indicator before beginning a cut. Do not exceed the tool manufacturer’s recommended depth-of-cut or feed-rate parameters for the workpiece material.
