Guhring 9054920200000 Square End Mill 0.7874in Pcd 2 Flute

Product Description

The GUHRING 9054920200000 is a single-end square end mill with a polycrystalline diamond (PCD) tipped cutting edge, engineered for high-performance machining of non-ferrous and abrasive materials. It carries a 0.7874 inch (20 mm) cutting diameter and a 0.4724 inch (12 mm) length of cut. The 4-degree helix angle and two-flute geometry support chip evacuation in demanding applications. The bright, uncoated finish is standard for PCD tooling of this type. This tool is installed and operated by machinists and CNC programmers working with precision milling equipment.

This end mill is suited for milling operations on non-ferrous workpiece materials, consistent with the primary workpiece material code N designation. Typical applications include finish and semi-finish milling of aluminum, composites, and other abrasive non-ferrous substrates in both production and job-shop environments. The straight-cylindrical shank with h6 tolerance fits standard collet and end mill holder systems. It belongs to GUHRING Series 5492 and is built to standard length specifications with no extended reach.

Key Features

• PCD tipped cutting edges for extended tool life in abrasive and non-ferrous materials
• Two-flute right-hand cut geometry with 4-degree helix angle for efficient chip removal
• Center-cutting capable, allowing plunge entry in applicable operations
• Straight-cylindrical shank at h6 tolerance for precise, repeatable tool holding
• Mill diameter tolerance h10 for consistent dimensional accuracy
• Bright/uncoated finish standard for PCD tooling applications

Compatibility

Designed for use with standard collet chucks and end mill holders accepting a 0.7874 inch (20 mm) straight-cylindrical shank. Compatible with CNC machining centers and manual mills configured for right-hand cut tooling. Verify spindle and holder clearance before use.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully powered down and locked out before inserting or removing the tool. Use a calibrated torque wrench with the appropriate collet nut to secure the shank within manufacturer-recommended clamping ranges for the holder type. Inspect the PCD cutting edges for chips or damage before each use, as PCD tips are brittle and sensitive to interrupted cuts in ferrous materials.
