Seco 17011630 Square End Mill 7/32 in 2 Flute Cobalt

Product Description

The SECO 17011630 is a single-end square end mill designed for material removal in ferrous and high-strength alloy applications. Manufactured from M42 cobalt high-speed steel, it provides better heat and wear resistance than standard M2 HSS tooling. The cutter measures 7/32 inch (0.2188 inch) in diameter with a 1/2 inch length of cut and a 3/8 inch shank diameter. A 30-degree right-hand spiral helix promotes efficient chip evacuation and reduces cutting forces. This tool ships bright and uncoated, which is appropriate for general-purpose milling where a coating is not required. Machinists and tool-and-die tradespeople are the primary users.

The 17011630 is suited for milling operations on steel, stainless steel, cast iron, and high-temperature alloys, covering ISO material codes P, M, K, and S. Its short-length geometry makes it well matched for slotting, profiling, and step milling on CNC machining centers and manual knee mills where rigidity is a priority. The 2-flute configuration provides adequate chip clearance when working softer steels or when chip load per tooth needs to remain manageable. Centercutting geometry allows plunge entry into the workpiece without pre-drilling.

Key Features

• M42 cobalt steel construction for improved heat resistance over standard HSS in demanding cuts
• 2-flute, right-hand spiral at 30 degrees for efficient chip evacuation
• Centercutting design allows direct plunge milling without a pre-drilled pilot hole
• Bright/uncoated finish suitable for general-purpose ferrous and high-temp alloy work
• Short flute length provides added rigidity and reduced deflection at small diameters
• Single-end configuration; Series SP205

Compatibility

Designed for use in standard 3/8 inch collets or end mill holders on CNC machining centers and manual milling machines. Primary workpiece materials include steel, stainless steel, cast iron, and high-temperature alloys (ISO P, M, K, S).

Installation Notes

A licensed machinist or trained toolroom technician should install and set this end mill. Secure the 3/8 inch shank in a properly sized collet or end mill holder and verify runout before cutting; maximum TIR is 0.0010 inch. Confirm spindle speed, feed rate, and depth of cut are appropriate for the workpiece material and machine rigidity before engaging the cut. Do not exceed the rated length of cut to avoid tool deflection or premature breakage.
