Accupro 14881852 Ball End Mill 0.0781 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14881852 is a miniature solid carbide ball end mill designed for precision milling operations in hardened and high-strength materials. Built from micrograin solid carbide, it delivers rigidity and wear resistance in demanding cutting environments. The 0.0781-inch (5/64-inch) diameter cutter features three right-hand spiral flutes with a 30-degree helix angle and a chipbreaker geometry that promotes chip evacuation in tight cutting zones. An AlTiN coating adds thermal resistance and extends tool life during high-speed and dry cutting. This single-end tool has a 0.5-inch length of cut and is suited for machinists and tool-and-die professionals working in CNC milling applications that require small-diameter, extended-reach capability.

This end mill is built for detailed contouring, slotting, and profiling work where fine feature resolution and tight tolerances are required. Its miniature series classification makes it appropriate for mold and die work, aerospace component machining, medical device manufacturing, and precision prototype work. The extended-reach design, with a 1.0-inch neck length and 2.5-inch overall length, allows access to deep pockets and narrow cavities that standard-length tools cannot reach. A 1/8-inch shank diameter provides a secure grip in compatible collet-style toolholders.

Key Features

• Micrograin solid carbide construction for hardness and dimensional stability
• AlTiN coating for elevated-temperature resistance and extended tool life
• 3-flute, right-hand spiral design with chipbreaker for efficient chip evacuation
• 30-degree helix angle optimized for smooth cutting action in ferrous and non-ferrous materials
• Extended-reach geometry with 1.0-inch neck length for deep-pocket access
• Tight diameter tolerance of +0.0000/-0.0010 inches for consistent fit and finish

Compatibility

Designed as an OEM-style miniature ball end mill for use in CNC machining centers and manual mills equipped with 1/8-inch collet or toolholder systems accepting standard shank diameters.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the collet to the recommended engagement depth before torquing the collet nut. Avoid side-loading the tool beyond rated cutting parameters, as the small diameter makes it susceptible to deflection and breakage if feeds and speeds are not properly set for the material being cut.
