Accupro 95168553 Ball End Mill 1/4 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 95168553 is a single-end ball end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from micrograin solid carbide, it delivers superior hardness and wear resistance compared to high-speed steel alternatives. The tool features a nACRo coating that reduces friction and extends tool life in demanding cutting environments. With a 1/4 inch mill diameter, 3/4 inch length of cut, and 2-1/2 inch overall length, this end mill is well suited for cavity work, contour milling, and profiling passes where a ball nose geometry is required.

This end mill is intended for use in CNC machining centers and manual milling machines where tight tolerances and consistent surface finishes are required. The 4-flute, right-hand spiral configuration with a high helix angle improves chip evacuation and supports higher feed rates. Variable helix geometry helps reduce chatter during deep cuts or long-reach applications. It is commonly installed by machinists and tool-and-die professionals working in job shops, production facilities, and aerospace or automotive component manufacturing environments.

Key Features

• Micrograin solid carbide construction for high hardness and edge retention
• nACRo coating reduces friction and extends tool life in high-temperature cuts
• 4-flute, right-hand cut and right-hand spiral for efficient chip removal
• Variable helix design minimizes vibration and chatter during milling
• High helix style supports aggressive feed rates and smooth finishes
• Single-end configuration with 1/4 inch shank for standard collet or end mill holder fitment

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill for CNC machining centers and manual mills accepting a 1/4 inch shank diameter toolholder or collet.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism according to the toolholder manufacturer's specifications. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates edge wear and reduces part quality.
