Harvey Tool 51012-C3 Ball End Mill 3/16 in 4 Flute Carbide

Product Description

The HARVEY TOOL 51012-C3 is a 4-flute, solid carbide ball end mill designed for high-performance milling in steel, stainless steel, and cast iron. It carries a 3/16 inch (0.1875 inch) mill diameter with a matching 3/16 inch straight-cylindrical shank, a 5/16 inch length of cut, and a 2 inch overall length. The AlTiN PVD coating improves heat resistance and tool life during ferrous machining. The 30-degree right-hand spiral flute geometry supports both roughing and finishing passes. This tool is sized for miniature and precision milling work and is typically installed and operated by machinists and toolroom professionals on CNC milling machines.

The 51012-C3 fits into miniature end mill applications where tight tolerances and small-feature geometry are required. It is well suited for die and mold work, aerospace components, and precision part machining in steel and stainless steel. With a stub-standard length profile, it offers increased rigidity compared to longer reach tools, making it effective for slotting, profiling, and contour milling in confined workpiece features. The single-end configuration is standard for this class of carbide end mill.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• AlTiN PVD coating for elevated heat resistance during steel and stainless steel milling
• 4-flute, right-hand spiral design supports both roughing and finishing operations
• 30-degree helix angle balances cutting efficiency and chip evacuation
• Stub-standard length profile maximizes rigidity in small-feature milling setups
• 0.0938 inch nose radius ball profile for accurate contour and 3D surface work

Compatibility

Designed as an OEM-style miniature ball end mill for use in CNC milling operations on steel, stainless steel, and cast iron workpieces, consistent with the Harvey Tool Miniature End Mills - Ball - Stub Standard series.

Installation Notes

Installation and operation should be performed by qualified machinists following standard CNC tooling procedures. Power down and lock out the spindle before changing tooling. Verify that the tool holder bore matches the 3/16 inch shank diameter before seating the tool. Do not exceed the manufacturer-rated speeds and feeds for the workpiece material and coating combination.
