Accupro 14556472 Ball End Mill 1/4 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 14556472 is a single-end ball end mill designed for precision milling of contoured surfaces, slots, and complex 3D profiles in ferrous and non-ferrous materials. Built from micrograin solid carbide, the tool offers high rigidity and wear resistance at elevated cutting speeds. The 40-degree right-hand spiral helix promotes efficient chip evacuation and reduces cutting forces. An AlTiN+ coating provides thermal and oxidation resistance, extending tool life in dry or minimum-quantity lubrication (MQL) machining environments. With a 0.2500-inch diameter and 0.7500-inch length of cut, this mill is well suited for fine-detail work in die, mold, and component machining applications.

This ball end mill is used in CNC machining centers for finishing and semi-finishing passes on hardened steels, alloy steels, stainless, and similar materials. The standard-length geometry and 1/4-inch shank make it compatible with common collet chucks and end mill holders found in production and job-shop environments. Machinists and CNC programmers select this tool for small-radius floor blending, core and cavity work, and contoured surface finishing where tight tolerances and surface quality are priorities.

Key Features

• Micrograin solid carbide construction for rigidity and extended tool life
• AlTiN+ coating for high-heat and oxidation resistance in ferrous machining
• 40-degree right-hand helix for efficient chip evacuation and smooth cutting action
• 4-flute geometry balances material removal rate with surface finish quality
• Ball end profile enables contour milling, 3D profiling, and radius blending
• Single-end design with standard-length reach for general CNC milling applications

Compatibility

Designed as a standard 1/4-inch shank ball end mill compatible with collet chucks, shrink-fit holders, and end mill holders sized for 1/4-inch shanks in CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and the machine is in a safe state before inserting or removing tooling. Confirm the holder bore and collet are clean and free of chips before seating the shank. Verify runout at the tool tip after clamping, as excessive runout will accelerate wear and degrade surface finish on ball-nose tools.
