Accupro 14883943 Ball End Mill 0.085 in 3 Flute Carbide

Product Description

The ACCUPRO 14883943 is a solid carbide ball end mill engineered for precision milling in tight-tolerance and miniature machining applications. With a 0.0850-inch cutting diameter and a 3-flute spiral geometry, this tool delivers efficient chip evacuation and smooth surface finishes in ferrous and non-ferrous materials. The micrograin carbide construction provides rigidity and wear resistance suited to high-speed CNC operations. A 30-degree helix angle balances cutting forces for reduced chatter, making it a reliable choice for machinists working in die, mold, and precision component work.

This end mill is designed for use in vertical machining centers and CNC milling operations where small-diameter, extended-reach tooling is required. The miniature series classification and 0.4250-inch neck length make it well suited for deep-pocket profiling, slot milling, and contour work where standard-length tools cannot reach. The bright, uncoated finish makes it appropriate for use in aluminum, brass, and other non-ferrous materials, as well as general-purpose steel applications where coating is not required. A 1/8-inch shank diameter allows it to seat in standard collets and tool holders common to CNC setups.

Key Features

• 0.0850-inch ball cutting diameter with a tolerance of +0.0000 / -0.0010 inches for consistent dimensional accuracy
• 3-flute spiral geometry with a 30-degree helix angle for efficient chip removal and reduced cutting forces
• Micrograin solid carbide construction for superior hardness and extended tool life
• 0.4250-inch neck length provides extended reach into deep pockets and contoured features
• Single-end, right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Bright, uncoated finish suitable for non-ferrous and general-purpose milling without coating interference

Compatibility

Designed as an OEM-style miniature ball end mill compatible with standard 1/8-inch collets and CNC tool holders used in vertical machining centers and precision milling applications.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle at a full stop and the machine in a locked-out, de-energized state. Seat the 1/8-inch shank fully into a matched collet or tool holder and torque to the machine manufacturer's specified clamping value. Verify runout with a dial indicator before beginning a cut. Do not exceed the tool's rated cutting diameter or depth of cut for the material being machined.
