Accupro 14883949 Ball End Mill 0.0750 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14883949 is a solid carbide ball end mill designed for high-precision milling of complex contoured surfaces, cavities, and 3D profiles. At 0.0750 inches in diameter with a 3-flute geometry and a 30-degree helix angle, this tool is built for tight-tolerance work in hardened and difficult-to-machine materials. The AlTiN coating provides thermal resistance and extended tool life in dry or minimal-lubrication cutting conditions. Micrograin carbide construction contributes to edge sharpness and rigidity at small diameters. This end mill is appropriate for CNC machining center applications where surface finish and dimensional accuracy are critical requirements.

This miniature-series ball end mill is suited for precision machining operations including die and mold work, medical component machining, aerospace part finishing, and small-feature cavity milling. The extended reach design, with a 0.6250-inch neck length, allows access to deeper features without sacrificing rigidity. The 1/8-inch shank diameter fits standard ER collet systems and toolholders common in vertical machining centers and high-speed spindle setups. Single-end configuration means the tool is replaced rather than flipped when the cutting edge is worn.

Key Features

• 0.0750-inch ball nose diameter with mill diameter tolerance of +0.0000 / -0.0010 inches for tight dimensional control
• 3-flute spiral flute geometry for improved chip evacuation and surface finish at small diameters
• AlTiN coating for high-heat resistance and extended tool life in alloy steels, stainless, and hardened materials
• Micrograin solid carbide construction for edge integrity and rigidity at miniature scale
• 0.6250-inch neck length with extended reach for deep-cavity and contour milling access
• 30-degree helix angle balances cutting forces and chip flow in fine-pitch applications

Compatibility

Designed for use in CNC machining centers with 1/8-inch ER collet toolholders or equivalent precision collet systems; shank diameter tolerance is -0.0001 / -0.0003 inches for consistent runout performance in high-speed spindle applications.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 1/8-inch shank fully into the collet and torque the collet nut to the toolholder manufacturer's specification using the appropriate spanner wrench. Verify runout with a dial indicator before commencing cuts, as excessive runout at this diameter will accelerate edge wear and reduce dimensional accuracy.
