Harvey Tool 18893-C6 Ball End Mill 0.093 in 2 Flute Carbide

Product Description

The HARVEY TOOL 18893-C6 is a miniature solid carbide ball end mill designed for high-precision milling in ferrous and hard materials. With a 0.093 inch cutting diameter, a 0.14 inch length of cut, and a tapered-reach extended neck measuring 1.86 inches, this tool reaches into deep pockets and complex contours without sacrificing rigidity. The AlTiN Nano PVD coating delivers elevated heat resistance and surface hardness, making it well suited for both roughing and finishing passes in steel, stainless steel, cast iron, and hard materials. It is used by machinists and CNC programmers in tool and die, aerospace component, and precision parts applications.

This end mill fits standard 1/4 inch straight-cylindrical shank toolholders and is sized for CNC machining centers, high-speed spindles, and precision manual mills where miniature tooling is required. The 30-degree right-hand helix and two-flute geometry support chip evacuation in slotting, profiling, and finishing operations on ferrous alloys and hard workpiece materials rated under ISO material codes P, M, K, and H. The stub-length classification and 2.0 inch reach make it a practical choice for cavities and contoured surfaces that require extended reach with minimal deflection.

Key Features

• 0.093 inch ball cutting diameter with a 0.0465 inch nose radius for precise contour and 3D surface work
• AlTiN Nano PVD coating for high-temperature resistance in steel, stainless steel, cast iron, and hard materials
• 1.86 inch neck length and 2.0 inch reach length provide extended access into deep pockets and features
• 30-degree right-hand helical flutes promote efficient chip flow during both roughing and finishing cuts
• Single-end, two-flute solid carbide construction with straight-cylindrical 1/4 inch shank for broad toolholder compatibility
• Mill diameter tolerance of +0.0000 / -0.0010 inches for tight dimensional control on finished surfaces

Compatibility

Designed for use in standard 1/4 inch straight-cylindrical shank toolholders on CNC machining centers and precision mills. Intended for machining steel, stainless steel, cast iron, and hard materials as defined by ISO material codes P, M, K, and H.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the shank to the full recommended grip depth in the toolholder collet or chuck, and verify runout with a dial indicator before beginning a cut. Avoid exceeding the manufacturer's recommended depth-of-cut guidelines for miniature carbide tooling, as small-diameter carbide is brittle and susceptible to breakage under excessive lateral load.
