Guhring 9036890080000 Square End Mill 0.315 in 6 Flute

Product Description

The GUHRING 9036890080000 is a solid carbide square end mill designed for precision material removal in demanding machining applications. Part of the Series 3689 line, this single-end tool features a 45-degree helix angle and FIREX coating, which provides thermal resistance and reduces friction during high-speed cutting operations. With 6 flutes and a 0.315-inch cutting diameter, it delivers superior surface finishes and chip evacuation. The centercutting geometry allows for plunge entry. This tool is intended for use by machinists and CNC operators working in production and job shop environments.

This end mill is suited for milling ferrous metals, non-ferrous alloys, stainless steel, and high-temperature alloys, consistent with its primary workpiece material codes covering cast iron, stainless, steel, and superalloys. The FIREX finish makes it particularly effective when cutting hard materials. It is configured with a straight cylindrical shank for standard collet or end mill holder retention on vertical and horizontal machining centers as well as manual knee mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard material applications
• FIREX coating for high-temperature performance and extended tool life
• 6-flute design for improved surface finish and feed rates
• 45-degree helix angle promotes smooth cutting action and efficient chip flow
• Centercutting capability allows direct plunge milling
• Right-hand cut and right-hand spiral flute configuration
• Straight cylindrical shank with h6 tolerance for precise holder fit

Compatibility

Designed for use with standard straight-bore collets and end mill holders accepting an 8 mm (0.315-inch) shank. Suitable for primary workpiece materials coded K (cast iron), M (stainless steel), P (steel), and S (superalloys), with secondary suitability for hard materials (H) and non-ferrous materials (N).

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Tighten the collet or set screw to the holder manufacturer's specified procedure. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates wear on multi-flute solid carbide tooling.
