Accupro 14881885 Ball End Mill 0.25 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 14881885 is a single-end ball end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide, it delivers rigidity and edge retention in demanding cutting applications. The 0.25-inch diameter tool features a 0.75-inch length of cut and a 30-degree helix angle, making it well suited for finishing passes and contour work in tight geometries. With 4 spiral flutes and a right-hand cutting direction, it promotes efficient chip evacuation. The bright, uncoated finish is appropriate for general-purpose use across a range of work materials. Machinist and CNC operators typically run this tool in both vertical and horizontal machining centers.

This miniature-series end mill is intended for applications where small cutter diameter and precise ball-nose geometry are required. It fits residential and light industrial machine shops, tool rooms, and production floors running CNC milling equipment. Typical use cases include 3D contouring, slotting, and profiling of small features in steel, aluminum, and similar machinable metals. The 0.25-inch shank diameter is compatible with standard collet holders and end mill adapters of matching bore size.

Key Features

• Micrograin solid carbide construction for extended tool life and edge stability
• Ball-nose geometry supports 3D contouring and radius profiling
• 4 spiral flutes with right-hand helix promote chip clearance and smooth cutting action
• 30-degree helix angle balances cutting force and surface finish quality
• Bright uncoated finish suitable for general-purpose milling applications
• Single-end design with no chipbreaker and no extended reach

Compatibility

Designed as an OEM-style replacement or direct-fit miniature ball end mill for CNC machining centers and manual mills accepting a 0.25-inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and machine is locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention nut per the toolholder manufacturer specification. Verify runout with a dial indicator before commencing cuts.
