Guhring 9035400200000 Square End Mill 0.787 in 3 Flute Carbide

Product Description

The GUHRING 9035400200000 is a solid carbide square end mill designed for high-performance milling in demanding metalworking applications. Part of the Series 3540, it features a 0.787-inch (20 mm) cutting diameter and a stub-length geometry with a 0.787-inch length of cut. The 45-degree helix angle promotes aggressive chip evacuation and reduced cutting forces. Three flutes provide a balance of chip clearance and edge strength. The FIREX coating delivers elevated heat resistance and extended tool life in ferrous and hardened materials. Licensed machinists and CNC operators are the primary users of this tool.

This end mill is suited for general-purpose milling, slotting, and peripheral cutting in ferrous metals, alloy steels, and similar materials where a hard, heat-resistant coating is required. The stub-length body provides rigidity, making it a strong choice for applications where deflection and chatter must be minimized. The centercutting design allows plunge entry directly into the workpiece. Right-hand cut and right-hand spiral flute configuration is standard for conventional CNC vertical and horizontal machining centers.

Key Features

• 0.787-inch (20 mm) cutting diameter with 0.787-inch (20 mm) length of cut in stub configuration
• FIREX coating for heat resistance and extended tool life in ferrous materials
• 45-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge milling without a pre-drilled entry hole
• Solid carbide construction provides rigidity and wear resistance superior to HSS tooling
• Right-hand cut, right-hand flute — compatible with standard CNC spindle direction

Compatibility

Designed as an OEM-style replacement or direct-fit option for Series 3540 solid carbide square end mill applications requiring a 20 mm shank diameter and stub-length geometry on standard CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Use a calibrated tool holder matched to the 0.787-inch (20 mm) shank diameter and torque the retention mechanism per the tool holder manufacturer specification. Verify runout with a dial indicator before initiating a cut, as excessive runout accelerates edge wear on carbide tooling.
