Guhring 9030860111100 Square End Mill 7/16 in 3 Flute

Product Description

The GUHRING 9030860111100 is a solid carbide square end mill designed for high-performance milling in ferrous and hard-to-machine materials. Part of the Series 3086 line, this stub-length tool features a 7/16 inch cutting diameter, a 5/8 inch length of cut, and a 45-degree helix angle. The FIREX coating reduces friction and extends tool life in demanding cutting environments. With three flutes and a spiral flute geometry, it delivers efficient chip evacuation and a smooth cutting action. Licensed machinists and tool-and-die professionals commonly deploy this end mill on CNC vertical mills and machining centers.

This end mill is suited for slotting, profiling, and peripheral milling operations in cast iron, stainless steel, and steel. The stub length provides added rigidity, reducing deflection in tight-tolerance cuts. The straight cylindrical shank at 7/16 inch diameter fits standard ER collet chucks and end mill holders. It is a single-end, centercutting tool capable of plunge entry, making it practical for a wide range of roughing and semi-finishing applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• FIREX coating for reduced friction and extended tool life at elevated cutting temperatures
• 45-degree helix angle promotes smooth cutting action and efficient chip flow
• Centercutting design allows direct plunge milling without pre-drilling
• Stub length body minimizes overhang and deflection in precision milling operations
• Right-hand cut and right-hand flute spiral compatible with standard CNC spindle rotation

Compatibility

Designed for use with cast iron, stainless steel, and steel workpiece materials. Secondary compatible material categories include non-ferrous and superalloy applications per Series 3086 design parameters. Fits standard 7/16 inch straight-bore collet chucks and end mill holders.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Verify collet or holder bore matches the 7/16 inch shank diameter and that runout is within acceptable tolerance before cutting. Do not exceed manufacturer-recommended speeds and feeds for the workpiece material. Inspect the cutting edges for chipping or wear before each use.
