Accupro 12177598 Tapered Ball End Mill 3/32 in 3 Flute Carbide

Product Description

The ACCUPRO 12177598 is a tapered ball end mill designed for precision milling of contoured surfaces, slots, and die cavities. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding cutting operations. The small end diameter measures 3/32 inches with a nose radius of 3/64 inches, a 2-degree taper angle per side, and a 30-degree helix angle. With 3 spiral flutes and a right-hand flute direction, this tool produces smooth finishes on ferrous and non-ferrous materials. It is centercutting, allowing direct plunge entry into workpiece material without a pre-drilled hole.

This end mill suits CNC machining centers and manual milling operations where tight-radius profiling and tapered wall geometry are required. Common applications include mold and die work, aerospace component finishing, and precision part production. The 3/4-inch length of cut and 3/16-inch shank diameter make it well suited for shallow-to-moderate depth passes in confined areas. The uncoated finish is appropriate for use with cutting fluids on a wide range of workpiece materials.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• Ball end geometry with 3/64-inch nose radius for contoured and profiled surfaces
• 2-degree taper angle per side for tapered wall milling in mold and die applications
• 3 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge milling without pre-drilling
• Uncoated finish compatible with cutting fluid applications across multiple material types

Compatibility

Designed as a standard shank tapered ball end mill compatible with CNC and manual milling machine tool holders accepting a 3/16-inch round shank diameter.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state. Ensure the tool holder collet or chuck is clean and undamaged before seating the shank. Verify runout with a dial indicator before beginning a cut. Follow the machine manufacturer and tooling manufacturer guidelines for appropriate feed rate, spindle speed, and depth of cut for the workpiece material.
