Accupro 14881878 Ball End Mill 3/16 in 3 Flute Carbide

Product Description

The ACCUPRO 14881878 is a solid carbide ball end mill designed for precision milling in demanding machining applications. Built to miniature-series standards, this single-end tool features a 3/16 inch (0.1875 inch) mill diameter, a 9/32 inch length of cut, and a 3-flute spiral flute geometry with a 30-degree helix angle. The micrograin carbide construction delivers rigidity and edge retention in hardened materials, stainless steels, and high-temperature alloys. A bright, uncoated finish makes it suitable for use with cutting fluids or where coating buildup must be avoided. Machinists and CNC operators use this mill for profiling, slotting, and contouring in tight geometries.

This ball end mill is suited for CNC machining centers and manual knee mills in both job-shop and production environments. The extended-reach design accommodates deep-pocket and undercutting operations that standard-length tools cannot reach. Its 3/16 inch shank diameter fits standard collets and end mill holders. The chipbreaker feature aids chip evacuation during extended cuts in gummy or high-buildup materials. Applications include die and mold work, aerospace component finishing, and medical part contouring where small-diameter accuracy is critical.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• 3-flute spiral geometry with 30-degree right-hand helix for efficient chip evacuation
• Ball nose profile for 3D contouring and radius floor finishing
• Chipbreaker design reduces cutting forces in difficult materials
• Extended reach for deep-pocket and undercutting operations
• Bright/uncoated finish compatible with most cutting fluid chemistries

Compatibility

Designed as an OEM-style miniature-series ball end mill compatible with standard 3/16 inch collets and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before changing tooling. Seat the shank fully in the collet or holder to the recommended grip length and torque the retention hardware per the toolholder manufacturer specifications. Inspect the cutting edges and shank for runout before initiating a cut.
