Guhring 9031500063500 Square End Mill 0.25in 4 Flute Carbide

Product Description

The GUHRING 9031500063500 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. Built to Series 3150 specifications, it features a 0.25-inch cutting diameter, a 0.75-inch length of cut, and a 2.5-inch overall length. The 4-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Center-cutting capability allows for plunge entry as well as standard peripheral milling. This tool is installed and operated by machinists and CNC programmers working in job shops, manufacturing facilities, and tool rooms.

This end mill is suited for milling cast iron, stainless steel, and steel workpieces, covering material codes K, M, and P, with secondary capability in materials coded N and S. The straight cylindrical shank at 0.25 inches fits standard collet and end mill holders. The bright, uncoated finish and proprietary carbide grade make it a reliable general-purpose cutter for slotting, profiling, and contouring operations at appropriate cutting parameters for the workpiece material.

Key Features

• 0.25-inch cutting diameter with h10 mill diameter tolerance for consistent fit and finish
• 4-flute right-hand spiral design with 30-degree helix for balanced chip flow and surface finish
• Solid carbide construction for rigidity and wear resistance in ferrous materials
• Center-cutting geometry allows direct plunge milling without pre-drilling
• Straight cylindrical shank (h6 tolerance) for secure seating in standard collet holders
• Single-end configuration; uncoated bright finish for compatibility with a wide range of cutting fluids

Compatibility

Designed as a direct-fit replacement-style solid carbide square end mill for standard 0.25-inch collet and end mill holder tooling systems; compatible with primary workpiece materials cast iron, stainless steel, and steel (material codes K, M, P) and secondary materials coded N and S.

Installation Notes

Installation is performed by qualified machinists or CNC tooling personnel. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Seat the shank fully into the collet or end mill holder and torque the retention mechanism to the tool holder manufacturer specification. Verify runout with a dial indicator before production cuts, particularly in tight-tolerance applications.
