Harvey Tool 12016 Ball End Mill 0.25 in 2 Flute Pcd

Product Description

The HARVEY TOOL 12016 is a single-end ball end mill designed for high-performance material removal in non-ferrous metals, plastics, graphite, and carbon fiber. It features a 0.25-inch mill diameter, a 0.312-inch length of cut, and a 2-flute straight-flute geometry brazed with a polycrystalline diamond (PCD) coating applied via PVD process. The 0 degree helix angle and stub-length profile make this tool well-suited for applications where rigidity and surface finish are priorities. At 0.06 pounds, it is a compact, precision-ground carbide tool intended for use by machinists and tooling professionals working in CNC milling operations.

This ball end mill is built for stub-length, extended-reach applications in CNC machining centers handling non-ferrous workpieces. The 0.75-inch reach length and 0.438-inch neck length allow access to stepped or recessed features without sacrificing rigidity. It is appropriate for both roughing and finishing passes on materials including aluminum, brass, copper, plastic, graphite, and carbon fiber composite. Right-hand cutting and right-hand flute direction are standard. It is not designed for ferrous metal cutting.

Key Features

• Polycrystalline diamond (PCD) coating via PVD process for extended tool life on abrasive non-ferrous materials
• 0 degree helix angle with straight flute geometry for controlled chip evacuation in graphite and composite applications
• 0.75-inch reach length with extended-reach geometry for accessing recessed features
• Single-end ball nose profile with 0.125-inch nose radius for accurate radius profiling and contouring
• Straight-cylindrical shank at 0.25 inches for standard ER collet or end mill holder compatibility
• Suitable for both roughing and finishing operations in a single tool

Compatibility

Designed for use on non-ferrous metals, plastics, graphite, and carbon fiber in CNC milling applications. Part of the HARVEY TOOL Diamond End Mills for Non-Ferrous Materials series (PCD Diamond Ball). Not intended for ferrous metal machining.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine in a safe, locked-out state. Secure the 0.25-inch straight-cylindrical shank in a properly sized ER collet or end mill holder, torqued to the tool holder manufacturer specifications. Verify runout after installation before engaging the workpiece. Consult machine manufacturer guidelines and applicable shop safety standards before operation.
