Harvey Tool 769112-C8 Square End Mill 3/16 in 3 Flute Carbide

Product Description

The HARVEY TOOL 769112-C8 is a solid carbide square end mill engineered for precision milling in metal and composite materials. It features a 3/16 inch (0.1875 inch) cutting diameter with a 9/16 inch (0.5630 inch) length of cut and a 1/8 inch straight-cylindrical shank. The tool carries a Titanium Diboride (TiB2) coating, which reduces friction and extends tool life in ferrous and non-ferrous applications. A variable helix geometry minimizes chatter and improves chip evacuation, making this end mill well suited for finishing passes and complex contour work. It is a single-end, right-hand cut, right-hand flute design with a chipbreaker and centercutting capability.

This end mill is used in CNC machining centers and manual mills for slotting, profiling, and plunging operations. The long flute type and 2 inch overall length make it a practical choice where moderate reach is needed without sacrificing rigidity. The TiB2 coating makes it particularly effective in aluminum, copper, and other non-ferrous materials as well as certain hardened steels. Machinists, tool-and-die makers, and CNC operators working in job shops, aerospace, and precision manufacturing environments typically specify this tool.

Key Features

• 3/16 inch cutting diameter with 9/16 inch length of cut for detail and finish milling
• Titanium Diboride (TiB2) coating reduces friction and extends tool life
• Variable helix flute geometry reduces chatter and improves chip flow
• Chipbreaker design aids chip control during deeper cuts
• Centercutting capable — supports direct plunge entry
• Single-end, right-hand cut with straight-cylindrical 1/8 inch shank

Compatibility

Designed as an OEM-style replacement or direct-application solid carbide end mill for CNC machining centers and manual mills accepting a 1/8 inch straight-cylindrical shank.

Installation Notes

This tool is installed and changed by machinists or CNC operators. Always power down and lock out the spindle before changing tooling. Secure the shank fully within the collet or tool holder to the depth specified by the holder manufacturer, and verify runout before cutting. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.
