Sgs 37325 Square End Mill 0.5in 5-flute Solid Carbide

Product Description

The SGS 37325 is a solid carbide square end mill engineered for high-performance metal removal in demanding machining applications. It features a 0.5 inch cutting diameter, five flutes, and a 37-degree helix angle with a variable index design that reduces harmonic vibration and chatter during aggressive cuts. The cutting edges carry a Titanium Nitride (TiN) coating that extends tool life by improving surface hardness and lubricity. Manufactured from micrograin carbide, the 37325 holds tight tolerances across a range of workpiece materials and is suited for milling operations run on CNC machining centers by machinists and tool-and-die professionals.

The SGS 37325 belongs to the Z5S series and is designed for use on ferrous alloys, stainless steels, titanium alloys, cast irons, high-temperature superalloys, and general steel applications as indicated by its primary material codes H, K, M, P, and S. The straight-cylindrical shank fits standard ER collet chucks, end mill holders, and hydraulic chucks with a 0.5 inch bore. The regular-length geometry makes it a practical choice for slotting, profiling, contouring, and peripheral milling at typical reach depths without the deflection risk of long-reach variants.

Key Features

• 5-flute design with variable index spacing reduces chatter and improves surface finish
• 37-degree helix angle promotes efficient chip evacuation and aggressive feed rates
• Titanium Nitride (TiN) coating increases surface hardness and extends cutting edge life
• Micrograin solid carbide construction maintains rigidity and edge sharpness at elevated cutting temperatures
• Center-cutting geometry allows direct plunge entry into workpiece material
• Right-hand cut, right-hand spiral flute configuration compatible with standard spindle rotation

Compatibility

Designed for use in standard 0.5 inch end mill holders, ER collet chucks, and hydraulic chucks on CNC vertical and horizontal machining centers. Suitable for machining ferrous steels, stainless steels, cast irons, titanium alloys, and high-temperature superalloys per Z5S series application guidelines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding torque and runout specifications. Confirm holder bore cleanliness and check radial runout at the cutting diameter before beginning a production run. Set appropriate spindle speed and feed rate per the material being cut and the manufacturer's speeds-and-feeds data for the Z5S series. Never exceed the rated depth of cut for the flute length or shank diameter to avoid tool breakage.
