Accupro 12463578 Ball End Mill 0.02 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12463578 is a miniature solid carbide ball end mill designed for precision milling operations requiring tight tolerances and fine detail work. With a 0.02-inch cutting diameter and a 0.06-inch length of cut, this single-end mill is built for small-feature machining in hardened and non-ferrous materials. The micrograin carbide construction delivers edge retention and rigidity at small diameters where tool deflection is a constant concern. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Machinists and tool-and-die professionals working on molds, dies, and precision components are the primary users of this tool.

This end mill is suited for CNC milling centers and manual mills where miniature contouring, slotting, and profiling are required. The 1/8-inch shank diameter makes it compatible with standard collet systems. Its uncoated micrograin carbide construction is well matched to non-ferrous metals, graphite, plastics, and some hardened steels at appropriate speeds and feeds. The regular-length configuration keeps overhang minimal, which is critical at this diameter to maintain rigidity and dimensional accuracy.

Key Features

• 0.02-inch ball nose diameter for fine-detail and small-feature milling
• Solid micrograin carbide construction for edge retention and rigidity
• 30-degree right-hand spiral flute for efficient chip evacuation
• 2-flute geometry balances chip clearance with cutting edge strength
• Uncoated finish suitable for a wide range of compatible materials
• 1/8-inch shank fits standard collet and toolholder systems

Compatibility

Designed as an OEM-style miniature ball end mill compatible with CNC and manual milling machines equipped with standard collet systems accepting a 1/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with proper toolholder torque and runout specifications for miniature end mills. Ensure the collet and holder are clean and free of debris before seating the shank, as contamination significantly increases runout at small diameters. Power down and lock out the spindle before changing tooling. At 0.02-inch diameter, excessive clamping depth or side load during setup can cause tool breakage prior to first cut.
