Accupro 12177269 Ball End Mill 0.0197 in 2 Flute Carbide

Product Description

The ACCUPRO 12177269 is a solid carbide ball end mill designed for precision milling of contoured surfaces, complex 3D profiles, and fine detail work in metalworking and machining applications. With a 0.0197-inch (0.50 mm) cutting diameter and a matching 0.0197-inch (0.50 mm) length of cut, this tool is built for micro-scale operations where dimensional accuracy is critical. The 2-flute, right-hand cutting geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. Micrograin carbide construction delivers the hardness and rigidity required at this scale without sacrificing edge integrity.

This end mill is suited for shops running small-feature work in ferrous and non-ferrous metals, mold and die applications, and precision component manufacturing. The extended reach design, with a 10.00 mm reach length and a 0.48 mm neck diameter, allows access to recessed features and deep pockets while maintaining centerline accuracy. The 4.00 mm shank diameter provides a stable interface with standard collet systems. Overall length is 50.00 mm. No coating is applied, making it a straightforward choice for materials and cutting conditions where an uncoated micrograin substrate performs optimally.

Key Features

• 0.50 mm (0.0197 inches) ball cutting diameter for micro-scale contouring and profiling
• Micrograin solid carbide construction for hardness and edge retention at small diameters
• 2-flute, right-hand cut with 30-degree helix for efficient chip evacuation
• Extended reach design with 10.00 mm reach length and 0.48 mm neck diameter
• 4.00 mm shank diameter compatible with standard collet toolholders
• Single-end, uncoated — ready to run without additional prep

Compatibility

Designed as an OEM-style replacement or direct-use tool for CNC machining centers and manual mills equipped with standard collet systems accepting a 4.00 mm shank diameter.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle at a full stop and machine power isolated. Ensure the collet and toolholder are clean and free of debris before seating the shank to the specified depth. At this diameter, tool runout is critical — verify runout with a dial indicator before cutting. Follow shop safety protocols and machine manufacturer guidelines for micro-diameter tooling.
