Gws 312013 Square End Mill 1/8 in 5 Flute Solid Carbide

Product Description

The GWS 312013 is a 5-flute, solid carbide square end mill designed for precision milling in demanding machining environments. It features a 1/8 inch mill diameter with a 0.1562 inch length of cut and a 2 inch overall length. The AlCrO-MAX coating provides elevated heat and wear resistance, making this end mill well-suited for high-speed cutting of hardened steels, stainless, and abrasive alloys. The 38-degree helix angle promotes efficient chip evacuation, while the submicron carbide grade delivers edge stability under aggressive feeds and speeds. Installed by machinists and tooling professionals in CNC milling operations.

This end mill is intended for use in small-diameter, high-precision milling applications where tight tolerances and fine surface finishes are required. The extended reach geometry and right-hand cutting direction make it applicable to slotting, profiling, and pocket milling in both prototype and production environments. It is a single-end tool with an upcut flute type, suited to vertical and horizontal CNC machining centers handling ferrous and non-ferrous materials. Series 2213 from GWS targets performance in difficult-to-machine alloys where standard coatings fall short.

Key Features

• 5-flute geometry increases feed rate capability and improves surface finish compared to fewer-flute designs
• AlCrO-MAX coating provides superior oxidation and abrasion resistance at elevated cutting temperatures
• 38-degree right-hand helix promotes smooth chip evacuation and reduces cutting forces
• Submicron solid carbide grade maintains edge integrity in hardened and abrasive workpiece materials
• Center-cutting design allows plunge entry without a pre-drilled starting hole
• Extended reach configuration suitable for deeper cavity access without sacrificing rigidity

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 1/8 inch straight shank end mill with a square shank type.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully within the collet or tool holder to the recommended engagement depth before tightening to prevent runout or pullout during operation. Verify spindle speed and feed rate parameters against the workpiece material and coating specifications before starting a cut. Inspect the cutting edges for chipping or wear before each use and replace the tool if edge integrity is compromised.
