Guhring 9031500071400 Square End Mill 0.2813 in 4 Flute Carbide

Product Description

The GUHRING 9031500071400 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. Built to Series 3150 standards, this single-end mill features a 0.2813-inch cutting diameter, a 0.75-inch length of cut, and a 30-degree helix angle with right-hand spiral fluting. The four-flute geometry provides efficient chip evacuation and a stable cutting action suited to ferrous and non-ferrous materials. At 2.5 inches overall length with a 0.3125-inch shank diameter, it fits standard collet and end mill holders on vertical mills, machining centers, and CNC routers. It ships bright and uncoated, which is appropriate for applications where coating is unnecessary or where re-grinding is anticipated.

This end mill is intended for use in professional machine shop environments, production facilities, and toolroom applications where dimensional accuracy and consistent surface finish are required. The regular-length flute geometry makes it a practical choice for slotting, peripheral milling, and light profiling in both ferrous and non-ferrous workpieces. It is not center-cutting, so plunge operations require a pre-drilled entry point. Machinists and CNC programmers working with small-diameter tooling in tight-tolerance applications will find the solid carbide construction appropriate for maintaining rigidity at elevated spindle speeds.

Key Features

• 0.2813-inch (9/32 inch) cutting diameter for small-feature and narrow-slot work
• Four flutes with right-hand spiral cut and 30-degree helix angle
• Solid carbide construction for rigidity and heat resistance at high RPM
• 0.75-inch length of cut in a regular-length configuration
• Bright, uncoated finish suitable for general-purpose or re-grindable tooling programs
• Not center-cutting — requires pre-drilled entry for plunge moves

Compatibility

Designed as an OEM-style solid carbide end mill for use in standard 5/16-inch collet chucks and end mill holders on manual vertical mills and CNC machining centers where small-diameter tooling is required.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and machine power is locked out before changing tooling. Seat the 0.3125-inch shank fully into the collet or holder to the recommended engagement depth before torquing the retention mechanism. Verify runout with a dial indicator after installation, as excessive runout will accelerate wear on small-diameter solid carbide tooling.
