Harvey Tool 35716 Ball End Mill 0.25 in 3 Flute Carbide

Product Description

The HARVEY TOOL 35716 is a solid carbide ball end mill designed for precision milling in steel, stainless steel, cast iron, and non-ferrous metals. The 0.25-inch diameter cutter features a 3-flute, right-hand helical geometry with a 30-degree helix angle, delivering a balance of chip evacuation and surface finish suited for both roughing and finishing passes. With a 6-inch overall length and extended reach of 3 inches, this tool is built for deep-cavity and hard-to-reach milling operations. The bright uncoated finish makes it a general-purpose choice when coating compatibility with a specific workpiece material is a concern. Licensed machinists and CNC mill operators are the primary end users.

This end mill is suited for CNC machining centers and manual mills handling tight-tolerance work in steel and non-ferrous metals. The stub flute length of 0.375 inches paired with a long reach shank allows the tool to machine deep slots, pockets, and contoured surfaces without the flute length causing interference. The 2.625-inch neck length provides clearance in deep-reach applications. It belongs to the Harvey Tool Miniature End Mills series and is packaged as a single unit.

Key Features

• 0.25-inch diameter ball nose with a 0.125-inch nose radius for contour and 3D surface milling
• 3-flute solid carbide construction for rigidity and wear resistance
• 30-degree right-hand helix for efficient chip evacuation in steel and stainless
• Extended reach design: 3-inch reach length and 2.625-inch neck length for deep-cavity access
• Stub flute (0.375 inches LOC) reduces deflection in deep-reach configurations
• Bright uncoated finish suitable for use across steel, cast iron, and non-ferrous workpieces

Compatibility

Designed for use in CNC machining centers and manual mills with a straight 0.25-inch collet or end mill holder. Rated for primary workpiece materials including steel, stainless steel, cast iron, and non-ferrous metals per ISO material codes P, M, K, and N.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. The machine spindle must be fully stopped and locked out before tool changes are made. Use a properly sized collet or end mill holder torqued per the machine manufacturer's specifications. Inspect the shank for runout and ensure the holder bore is clean and free of chips before securing the tool.
