Seco 17002338 Corner Chamfer End Mill 1/2 in 7 Flute Altin

Product Description

The SECO 17002338 is a solid carbide corner chamfer end mill designed for high-performance material removal in demanding metalworking applications. It features a 1/2 inch cutting diameter, a 2 inch length of cut, and 7 variable-index flutes with a 45-degree chamfer angle and a 0.0060 inch chamfer width. The AlTiN PVD coating provides thermal resistance and extended tool life at elevated cutting temperatures. Built from micrograin carbide, this end mill handles roughing and finishing operations including shouldering, slotting, ramp-down entry, helical interpolation, drill milling, and plunging. It is a single-end, right-hand cut tool with a straight cylindrical shank and a super close pitch flute configuration suited for tight-tolerance work.

This end mill is engineered for use on steel, stainless steel, cast iron, superalloys, and titanium workpiece materials. Its long flute length and extended reach make it well suited for deeper pocket work, cavity milling, and complex contour operations on CNC machining centers. The Series S738 designation places it within SECOs family of variable-index roughing and finishing tools intended for production environments where chatter suppression and tool life consistency are critical. It is appropriate for both job shop and high-volume production settings.

Compatibility

Designed for use on CNC machining centers and milling machines accepting a 1/2 inch straight cylindrical shank. Primary workpiece materials are steel, stainless steel, cast iron, superalloys, and titanium per material codes P, M, K, and S.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. The machine spindle must be fully stopped and the tool changer or spindle lock engaged before inserting or removing the tool. Use a properly sized collet or end mill holder matched to the 1/2 inch shank diameter to ensure secure clamping and minimize runout. Verify tool projection and reach against the programmed path before cutting to avoid interference with workholding or fixture components.
