Accupro 12463570 Ball End Mill 0.017in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12463570 is a miniature solid carbide ball end mill designed for precision milling operations in hardened and difficult-to-machine materials. With a 0.0170-inch cutting diameter and a 0.0510-inch length of cut (LOC), this tool is engineered for tight-tolerance work in small-feature applications. The AlTiN coating provides elevated heat resistance and surface hardness, extending tool life in demanding cutting conditions. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is specified by machinists and toolroom technicians working with CNC machining centers and high-speed spindles.

This miniature end mill is suited for milling small slots, pockets, and contoured surfaces in ferrous metals, hardened steels, stainless, and similar alloys. The 1/8-inch shank diameter fits standard collets and tool holders used on benchtop CNC machines, micro-machining centers, and precision die and mold work. Single-end configuration delivers one cutting end per tool. Right-hand cutting and right-hand flute direction are standard for conventional CNC setups.

Key Features

• Solid carbide micrograin substrate for rigidity and wear resistance in hard-material applications
• AlTiN coating increases surface hardness and thermal resistance for dry or semi-dry cutting
• 0.0170-inch ball nose diameter allows machining of very small radii and fine detail features
• 30-degree right-hand spiral flutes promote chip evacuation and reduce cutting forces
• 2-flute geometry balances chip clearance and cutting edge strength at miniature diameters
• Single-end design; Miniature series for micro-machining and precision toolroom use

Compatibility

Designed for use with standard 1/8-inch collets and precision tool holders on CNC machining centers and micro-milling spindles capable of accommodating miniature-series solid carbide end mills.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with CNC tooling and collet systems. Ensure the spindle and machine are fully powered down and locked out before changing tooling. Seat the shank fully in the collet to the recommended projection length and torque the collet nut per the tool holder manufacturer specifications. Inspect the cutting edges under magnification before use; miniature carbide tools are brittle and should never be forced into a cut beyond their rated parameters.
