Harvey Tool 54893-C6 Corner Radius End Mill 0.093 in 3 Flute

Product Description

The HARVEY TOOL 54893-C6 is a solid carbide corner radius end mill engineered for demanding material removal in high-temperature alloys, steels, stainless steels, cast iron, and hard materials. It measures 0.093 inches in diameter with a 0.01-inch corner radius and a 3/4-inch reach length, making it well-suited for long-reach, stub-flute applications where rigidity and precision are critical. The variable helix geometry reduces harmonic chatter and promotes chip evacuation during both roughing and finishing passes. An AlTiN (aluminum titanium nitride) PVD coating provides thermal resistance and extended tool life in high-heat cutting environments. This tool is single-end, right-hand cut, and center-cutting.

The 54893-C6 belongs to HARVEY TOOL's Variable Helix End Mills for High Temp Alloys series, specifically the Long Reach, Stub Flute, Corner Radius configuration. It is intended for precision machining operations in aerospace, die and mold, and general metalworking applications where tight tolerances and surface finish are required. The extended reach of 0.75 inches allows access to deep pockets and stepped features while the stub flute length limits deflection. This tool is typically set up by a CNC machinist or tool-and-die professional in high-precision toolholders as specified by the manufacturer.

Key Features

• Variable helix design reduces chatter and improves chip flow in difficult-to-machine alloys
• AlTiN PVD coating delivers thermal and wear resistance for high-temp alloy cutting
• 0.01-inch corner radius protects cutting edges and improves surface finish at part corners
• Extended reach (0.75 inches) with stub flute minimizes deflection in deep-pocket operations
• Center-cutting geometry allows plunge entry where required
• Right-hand flute direction and cutting action compatible with standard CNC spindle configurations

Compatibility

Designed for use with high-precision toolholders. Suitable for machining steel, stainless steel, cast iron, and hard alloys. Part of the HARVEY TOOL Variable Helix End Mills for High Temp Alloys - Corner Radius - Long Reach, Stub Flute series.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom professional. Secure the 1/8-inch straight cylindrical shank in a high-precision collet or toolholder to the manufacturer-recommended gauge length before use. Verify runout at the toolholder before starting the cut, as excess runout will accelerate wear on a tool of this diameter. Power down and lock out the machine spindle before changing or inspecting the tool.
