Accupro 12177648 Tapered Ball End Mill 1/4in 3 Flute Carbide

Product Description

The ACCUPRO 12177648 is a tapered ball end mill designed for precision milling of contoured surfaces, angled walls, and complex 3D profiles in CNC machining operations. Built from micrograin solid carbide, it delivers the rigidity and wear resistance required for hardened materials, stainless steels, and high-temperature alloys. The ball end geometry with a 1/8 inch nose radius produces smooth, accurate finishes on sculpted and drafted surfaces. With a 5-degree taper per side, 3 right-hand spiral flutes, and a 30-degree helix angle, this tool balances material removal with surface finish quality in finish and semi-finish passes.

This tapered ball end mill is suited for die and mold work, aerospace component machining, and precision part production where drafted or angled cavity walls are required. The 3/4 inch length of cut and 1/4 inch small end diameter make it well matched to tight-radius detail work and core or cavity contouring on vertical and horizontal machining centers. It is a centercutting tool, allowing plunge entry where the toolpath requires it. Typical users include CNC machinists and toolmakers working in job shops, moldmaking facilities, and production machine shops.

Key Features

• Micrograin solid carbide construction for extended tool life in demanding materials
• Ball end geometry with 1/8 inch nose radius for smooth contoured surface finishes
• 5-degree taper per side enables accurate machining of drafted walls and angled features
• 3 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design supports direct plunge entry
• Uncoated finish suitable for a wide range of general-purpose milling applications

Compatibility

Designed as an OEM-style replacement or direct tooling option for CNC machining centers and milling machines accepting a 3/8 inch round shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolmaker. Secure the 3/8 inch shank fully within the collet or end mill holder to the recommended engagement depth before tightening. Verify spindle and tool holding equipment are fully stopped and de-energized before tool changes. Inspect the cutting edges and shank for damage or runout before starting any operation.
