Seco 17002438 Square End Mill 1/16 in 2 Flute Carbide

Product Description

The SECO 17002438 is a solid carbide square end mill designed for precision material removal in metalworking applications. With a 0.0625-inch mill diameter and a 0.18-inch length of cut, this tool is built for tight-tolerance work in small-bore and fine-detail milling. The micrograin carbide construction delivers hardness and wear resistance suited to demanding cutting environments. A 30-degree helix angle promotes chip evacuation and smooth cutting action. Centercutting geometry allows the tool to plunge as well as mill laterally, adding versatility in multi-axis and CNC machining operations. It ships in a single-end, uncoated configuration as part of the ME230 series.

This end mill is suited for machining steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys. The 0.125-inch straight cylindrical shank fits standard collet and end mill holders commonly found on vertical machining centers and CNC milling machines. At 1.5 inches overall length, it is optimized for short-reach applications where rigidity and runout control are critical. It is well-suited to prototype shops, tool and die operations, and production environments requiring consistent performance at small diameters.

Key Features

• Solid micrograin carbide construction for hardness and long tool life
• Centercutting design enables both plunge and peripheral milling
• 30-degree helix angle promotes efficient chip evacuation
• Right-hand cut and right-hand flute spiral for standard CNC spindle compatibility
• Bright/uncoated finish suitable for a wide range of workpiece materials
• Two-flute configuration optimized for small-diameter precision cutting

Compatibility

Designed for use in standard collet chucks and end mill holders accepting a 0.125-inch straight cylindrical shank. Compatible workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys per ME230 series specifications.

Installation Notes

Installation and use of this end mill should be performed by a qualified machinist familiar with CNC or manual milling equipment. Ensure the spindle is fully stopped and the machine is locked out before loading or unloading the tool. Verify collet or holder runout does not exceed the tool TIR maximum of 0.0002 inches before commencing the cut. Follow the machine manufacturer guidelines and applicable shop safety procedures for small-diameter tooling, which is susceptible to breakage if feed rates or depths of cut are not appropriate for the material being machined.
