Guhring 9030860031700 Square End Mill 1/8 in 3 Flute Carbide

Product Description

The GUHRING 9030860031700 is a solid carbide square end mill designed for precision milling in demanding shop environments. Part of the Series 3086 line, it features a 1/8 inch cutting diameter, a 1/4 inch length of cut, and a 1-1/2 inch overall length. The 45-degree helix spiral flute geometry and FIREX coating work together to extend tool life and improve chip evacuation in ferrous and stainless materials. With three flutes and a centercutting design, this end mill handles both slotting and plunge operations. It is installed and operated by machinists and tool-and-die professionals on CNC mills and manual knee mills.

This end mill is suited for milling cast iron, stainless steel, and steel in both production and job-shop applications. The stub length configuration and straight cylindrical shank keep deflection low in tight-clearance setups. The right-hand cut, right-hand flute orientation is standard for conventional CNC milling operations. No coolant-through capability is present, so flood or mist cooling applied externally is the standard approach for these material groups.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• FIREX coating provides oxidation resistance and reduced friction at elevated cutting temperatures
• 45-degree helix angle promotes smooth chip flow and reduced cutting forces
• Centercutting design allows direct plunge entry into the workpiece
• Stub length reduces overhang and minimizes deflection in precision setups
• Mill diameter tolerance h10 and shank diameter tolerance h6 ensure consistent fit in standard collets

Compatibility

Primary workpiece materials include cast iron, stainless steel, and steel (material codes K, M, and P). Secondary workpiece material codes N and S are also supported. Designed for use in standard 1/8 inch collets or tool holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom procedures. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Seat the straight cylindrical shank fully in a clean, undamaged collet or end mill holder and torque the retention mechanism to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut.
