Guhring 9067760063500 5-flute Square End Mill

Product Description

The GUHRING 9067760063500 is a 5-flute square-end roughing and finishing end mill designed for high-efficiency material removal and surface finishing in a single tool. Built to Series 6776 specifications, it features a 45-degree helix angle and a Nano-A coating that extends tool life in demanding milling applications. The 0.25-inch diameter and 0.75-inch length of cut make it well-suited for slotting, profiling, and side milling operations in tight tolerances. Right-hand cutting with right-hand flute direction ensures compatibility with standard CNC and manual milling setups. Weighing approximately 0.01 pounds, it is a single-end tool of regular length at 2.5 inches overall.

This end mill is intended for use in precision machining environments where both roughing and finishing passes are required without a tool change. The 0.25-inch shank diameter fits standard ER collet chucks and end mill holders commonly found in CNC machining centers and manual knee mills. The Nano-A finish provides enhanced lubricity and wear resistance, making it appropriate for ferrous and non-ferrous materials in production and job-shop settings. Machinists and CNC operators in aerospace, general manufacturing, and tool-and-die applications will find this tool applicable to a range of milling strategies.

Key Features

• 5-flute geometry supports both roughing and finishing in a single pass
• 45-degree helix angle improves chip evacuation and reduces cutting forces
• Nano-A coating extends tool life and reduces heat buildup at the cutting edge
• Square end profile for flat-bottom slots, shoulders, and profiling cuts
• Right-hand cut and right-hand flute direction for standard spindle operation
• Regular length with 0.75-inch length of cut for rigid, accurate milling

Compatibility

Designed as a direct-fit replacement for 0.25-inch shank end mills in standard ER collet systems and end mill holders used in CNC machining centers and manual milling machines. Series 6776 classification applies.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a properly sized ER collet or end mill holder and torque the retention nut to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning the cut to prevent premature tool wear or workpiece damage.
