Accupro 12183995 Ball End Mill 0.3543 in 2 Flute Carbide

Product Description

The ACCUPRO 12183995 is a solid carbide ball end mill designed for precision milling operations in metal and composite materials. With a 0.3543-inch (9 mm) mill diameter and 2 right-hand spiral flutes, this single-end tool delivers controlled material removal and a consistent ball-nose profile for contouring, profiling, and 3D surface work. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Micrograin carbide construction provides the hardness and edge retention needed for demanding cuts in ferrous and non-ferrous workpiece materials. The uncoated finish makes it well-suited for use with cutting fluid or for materials where coated tools are not preferred.

This end mill fits standard CNC machining centers, knee mills, and manual mills equipped with a 10 mm collet or matching toolholder. It is used in job shops, toolrooms, and production environments where small-diameter ball-nose geometry is required for finish passes, radius features, or die and mold work. The 0.9843-inch (25 mm) length of cut and 70 mm overall length provide adequate reach for most shallow-to-medium-depth pockets without excessive tool deflection.

Key Features

• Micrograin solid carbide construction for hardness and edge retention
• 0.3543-inch (9 mm) ball nose diameter for contour and radius milling
• 2 right-hand spiral flutes with 40-degree helix angle for efficient chip evacuation
• 0.9843-inch (25 mm) length of cut suits shallow to medium pocket depths
• Single-end design with 10 mm shank diameter for standard collet toolholders
• Uncoated finish compatible with cutting fluid application

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC machining centers and manual mills using 10 mm collet systems requiring a 0.3543-inch solid carbide ball end mill.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet holder. Use a calibrated torque wrench and the collet nut specifications provided by the toolholder manufacturer when securing the shank. Inspect the cutting edges for chips or wear before each use and replace the tool at the first sign of edge degradation to maintain part quality and prevent tool breakage.
