Seco 17011832 Square End Mill 1 in 6 Flute Cobalt SPC408

Product Description

The SECO 17011832 is a single-end, square-profile cobalt end mill engineered for demanding metal-removal applications in production and job-shop environments. Built from M42 cobalt high-speed steel, it offers superior heat and wear resistance compared to standard M2 HSS tooling. The cutter measures 1 inch in diameter with a 4-inch length of cut and a 6-1/2-inch overall length, placing it in the long-series category suited for deep-pocket and extended-reach operations. The 6-flute geometry supports higher feed rates and improved surface finish in finishing and semi-finishing passes. The bright uncoated finish keeps regrinding straightforward and cost-effective.

This end mill is rated for use on steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys, covering a broad range of workpiece materials commonly encountered in aerospace, general machining, and mold-and-die work. The right-hand cut, right-hand spiral flute design and 30-degree helix angle provide stable chip evacuation in vertical and horizontal milling centers. The centercutting geometry allows direct plunge entry without a pre-drilled pilot hole, adding setup flexibility. The 1-inch shank diameter fits standard CAT, BT, HSK, and straight-bore toolholders in that bore size.

Key Features

• M42 cobalt construction for elevated heat resistance and longer tool life in tough alloys
• 6-flute configuration supports aggressive feed rates and improved surface finish
• 4-inch length of cut in a long-series (6-1/2-inch OAL) profile for deep-pocket reach
• Centercutting design enables direct plunge milling without a pilot bore
• 30-degree right-hand spiral helix promotes efficient chip evacuation
• Bright uncoated finish simplifies regrinding and is compatible with a wide range of cutting fluids

Compatibility

Rated for primary workpiece materials including steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys (material codes P, M, K, N, S). Part of the SECO SPC408 long-series end mill line. Fits any 1-inch-bore toolholder in compatible milling machine spindles.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Seat the shank fully into a clean, properly torqued toolholder and verify runout against the published TIR maximum of 0.0010 inches using a dial indicator before cutting. Power down and lock out the machine spindle before changing or adjusting tooling. Follow the machine manufacturer and tooling manufacturer feed-and-speed recommendations for the specific workpiece material to avoid premature edge wear or tool failure.
