Accupro 14883976 Ball End Mill 0.0450 in 3 Flute Carbide

Product Description

The ACCUPRO 14883976 is a miniature solid carbide ball end mill designed for precision milling operations in tight tolerances and small-feature work. With a 0.0450-inch mill diameter and a 0.0670-inch length of cut, this tool is built for fine detail passes in ferrous and non-ferrous materials. The micrograin carbide substrate provides the hardness and edge retention needed for demanding cuts at small scales. Three spiral flutes with a 30-degree helix angle promote efficient chip evacuation and a smooth cutting action. A licensed machinist or CNC operator will typically deploy this tool for finishing passes, engraving, and contour work on molds, dies, and precision components.

This miniature ball end mill is suited for CNC machining centers and high-speed spindle applications where small-diameter tooling is required. The extended reach design, with a 0.5500-inch neck length and 2.5-inch overall length, allows access to recessed features without sacrificing rigidity. The right-hand cut and right-hand flute direction make it compatible with standard CNC spindle rotation. It is commonly used in tool and die shops, medical device manufacturing, and aerospace component work where micro-feature geometry is critical.

Key Features

• 0.0450-inch ball nose diameter for fine detail and contour milling
• 3 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Micrograin solid carbide construction for hardness and edge retention
• Extended reach with 0.5500-inch neck length for access to recessed features
• Bright/uncoated finish suitable for a wide range of base materials
• Single-end design with 1/8-inch shank for standard collet fitment

Compatibility

Designed as a miniature single-end ball end mill with a 1/8-inch shank diameter, compatible with standard 1/8-inch collets and tool holders used in CNC machining centers and high-speed spindle setups.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 1/8-inch shank fully and evenly in the collet and torque the collet nut to the tool holder specification. At this diameter, runout control is critical — verify TIR before beginning a cut to avoid premature tool failure.
