Sgs 38513 Square End Mill 0.5in 5-flute Altin Solid Carbide

Product Description

The SGS 38513 is a solid carbide square end mill designed for high-performance material removal in demanding machining applications. Built on the Z5S series platform, it features a 0.5 inch mill diameter, a 1 inch length of cut, and a 3 inch overall length. The 5-flute geometry with a 37-degree helix angle supports aggressive feed rates while maintaining surface finish quality. AlTiN coating provides thermal resistance and extended tool life in high-temperature cutting environments. Variable index flute spacing reduces harmonic chatter during deep cuts. This end mill is suited for CNC machining centers where consistent geometry and tight tolerances are required.

The SGS 38513 is intended for milling operations across a broad range of workpiece materials including steels, stainless steels, cast irons, non-ferrous metals, and superalloys, as indicated by primary workpiece material codes H, K, M, P, and S. The 0.5 inch Weldon flat shank provides positive engagement in standard end mill holders, reducing pullout risk during heavy cuts. Regular length geometry makes it a practical choice for general-purpose peripheral and slot milling where extended reach is not required.

Key Features

• 5-flute spiral geometry with variable index for chatter reduction
• 37-degree helix angle supports aggressive feed rates and efficient chip evacuation
• AlTiN coating provides high-temperature resistance and extended tool life
• Micrograin solid carbide construction for rigidity and wear resistance
• Weldon flat shank for secure clamping and reduced pullout
• Right-hand cut, right-hand flute configuration for standard CNC spindle use
• Mill diameter tolerance of +0.0000 to -0.0012 inches for consistent fitment

Compatibility

Designed for use in standard 1/2 inch end mill holders and Weldon-style tool holders on CNC machining centers. Compatible with workpiece material categories H, K, M, P, and S as specified by the manufacturer for the Z5S series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before mounting or removing tooling. Secure the Weldon flat against the set screw in the tool holder to the appropriate holder specification to prevent axial pullout. Verify runout with a dial indicator before beginning a production run to confirm proper seating.
