Accupro 12184430 Ball End Mill 1 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12184430 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 1 inch cutting diameter and a 2.25 inch length of cut, this tool handles deep-cavity profiling, contouring, and finishing passes where rigidity and edge retention matter. The 3-flute geometry balances chip evacuation with wall finish quality. Micrograin carbide construction provides superior hardness and wear resistance compared to standard carbide grades. The 40-degree helix angle promotes smooth cutting action and reduces chatter during aggressive passes. Licensed machinists and CNC programmers working in job shops, tool rooms, and production environments are the primary users.

This end mill suits vertical and horizontal CNC machining centers running general profiling, slotting, and 3D contouring work. The single-end, right-hand cutting and right-hand flute configuration is standard for conventional CNC setups. The long-length designation with a 5 inch overall length provides reach into deep pockets and molds where a standard-length tool cannot access the full feature depth. The uncoated finish makes it a practical choice for aluminum and other non-ferrous materials where coatings can cause built-up edge or adhesion issues.

Key Features

• 1 inch cutting diameter with 2.25 inch length of cut for deep-pocket profiling
• 3-flute spiral geometry balances material removal rate with surface finish
• Micrograin solid carbide construction for extended tool life and edge stability
• 40-degree right-hand helix for reduced cutting forces and smoother chip flow
• Long overall length of 5 inches provides reach into deep molds and cavities
• Uncoated finish suited for aluminum, brass, and other non-ferrous workpiece materials

Compatibility

Designed as a single-end ball nose end mill compatible with standard 1 inch collet chucks, hydraulic chucks, and shrink-fit toolholders used on CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool changer is in a safe state before loading or removing the tool. Verify runout at the cutting edge after clamping using a dial test indicator, as excessive runout accelerates tool wear and degrades surface finish. Confirm programmed speeds and feeds are appropriate for the workpiece material and the long-length overhang before beginning the cut.
