Accupro 12183938 Ball End Mill 0.1719 in 2 Flute Carbide

Product Description

The ACCUPRO 12183938 is a solid carbide ball end mill designed for precision milling operations in metal and composite materials. Built from micrograin carbide, it delivers a 0.1719-inch cutting diameter with a 0.625-inch length of cut and a 2-inch overall length. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. With two right-hand flutes and a right-hand cutting direction, this single-end mill is suited for profiling, contouring, and slotting passes where tight tolerances and consistent tool life matter. It arrives uncoated, making it ready for use or compatible with aftermarket coating processes.

This end mill is used in CNC machining centers and manual milling machines for finish and semi-finish passes on ferrous and non-ferrous workpieces. The 3/16-inch shank diameter fits standard ER collet chucks and end mill holders commonly found in job shops, tool rooms, and production machining environments. It is typically installed by machinists and CNC operators working in industrial manufacturing, mold making, and precision component fabrication where small-diameter tooling is required.

Key Features

• Micrograin solid carbide construction for superior wear resistance and edge retention
• 0.1719-inch ball nose diameter for precise radius profiling and contouring
• 40-degree helix angle for efficient chip flow and reduced cutting forces
• Two right-hand spiral flutes with right-hand cutting direction
• Single-end design with uncoated finish
• Mill diameter tolerance of +0.000 to -0.002 inches for repeatable fitment

Compatibility

Designed as a direct-fit replacement or standard addition for CNC machining centers and manual mills accepting a 3/16-inch shank diameter end mill holder or ER collet system.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before loading or removing tooling. Secure the shank fully within the collet or end mill holder to the manufacturer-recommended engagement depth, and verify runout with a dial indicator before cutting. Follow shop safety protocols and applicable OSHA machine guarding requirements during setup.
