Accupro 12184055 Ball End Mill 0.7874 in 2 Flute Carbide

Product Description

The ACCUPRO 12184055 is a solid carbide ball end mill designed for precision milling operations in metal cutting applications. With a 0.7874 inch (20 mm) mill diameter and a 1.4961 inch (38 mm) length of cut, this tool delivers consistent performance in contouring, profiling, and finishing passes. The 2-flute configuration and 40-degree right-hand helix promote efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, the tool offers high rigidity and wear resistance compared to high-speed steel alternatives. The uncoated finish makes it suitable for a range of base material types where coating interaction is a concern. Machinists and tool-and-die professionals are the primary users of this end mill.

This ball end mill is suited for CNC machining centers and manual mills performing 3D contouring, cavity work, and finish milling on ferrous and non-ferrous materials. The single-end design concentrates mass in the shank for stability in deeper reach applications. The 20 mm shank diameter matches the mill diameter, allowing direct collet or end mill holder mounting without adapter reduction. The 100 mm overall length provides adequate reach for most standard workpiece setups without introducing excessive overhang.

Key Features

• Micrograin solid carbide construction for high hardness and edge retention
• 0.7874 inch (20 mm) ball nose diameter for accurate radius generation in contoured surfaces
• 40-degree right-hand spiral helix for aggressive chip evacuation
• 2-flute design balances chip clearance with cutting edge strength
• Uncoated finish for broad material compatibility without coating-related adhesion concerns
• Single-end configuration with 20 mm shank diameter for direct toolholder mounting

Compatibility

Designed for use in standard end mill holders, collet chucks, or shrink-fit holders accepting a 20 mm shank diameter on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the machine spindle is fully stopped and the control is in a safe state before changing tooling. Verify runout with a dial test indicator after seating the tool in the holder, as excessive runout accelerates carbide edge chipping. Confirm spindle RPM and feed rate settings are appropriate for the workpiece material and depth of cut before engaging the cut.
