Seco 17011754 Square End Mill 5/8 Inch 4 Flute Cobalt

Product Description

The SECO 17011754 is a cobalt square end mill built for demanding metal-removal applications in professional machining environments. Ground from M42 cobalt high-speed steel, it delivers heat resistance and edge toughness that standard HSS tooling cannot match. The cutter measures 0.625 inches in diameter with a 4-inch length of cut and a 6.125-inch overall length. The 30-degree helix spiral flute geometry promotes efficient chip evacuation, while the bright uncoated finish keeps the surface true for workpieces where coating residue or dimensional buildup is a concern. This tool is installed and run by machinists and CNC operators working in job shops, maintenance facilities, and production environments.

The 17011754 is suited for milling steel, stainless steel, cast iron, aluminum and non-ferrous materials, and high-temperature alloys. Its centercutting capability allows direct plunge entry without a pre-drilled pilot hole, making it practical for slot milling, pocketing, and ramping operations. The four-flute configuration balances feed rate capacity with chip clearance, making it a general-purpose choice for regular-length applications across a wide range of workpiece materials. This is a single-end, right-hand cut, right-hand flute tool from the SECO SPC408 series.

Key Features

• M42 cobalt construction for elevated heat and wear resistance over standard HSS
• 4-inch length of cut supports deep slot and pocket work in a regular-length form factor
• 30-degree helix angle promotes smooth cutting action and efficient chip flow
• Centercutting design allows plunge milling without a pre-drilled entry point
• Bright uncoated finish suits applications where coating interaction with the workpiece is undesirable
• Right-hand cut and right-hand flute for use in standard spindle rotation

Compatibility

Designed as an OEM-style replacement and standard production end mill for use in milling machines and machining centers accepting a 0.625-inch straight shank. Rated for steel, stainless steel, cast iron, aluminum and non-ferrous, and high-temperature alloy workpieces per SECO SPC408 series specifications.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Secure the shank in a properly sized end mill holder or collet chuck and verify runout does not exceed the specified TIR maximum before cutting. Confirm spindle speed and feed rate are set per the tool manufacturer guidelines for the specific workpiece material before engaging the cut. Inspect the cutting edges for wear or chipping before each use; a damaged edge on a centercutting end mill can cause workpiece damage or tool breakage during plunge entry.
