Accupro 14788683 Ball End Mill 0.203 in 4 Flute Carbide

Product Description

The ACCUPRO 14788683 is a solid carbide ball end mill designed for precision milling operations in metal and composite materials. With a 0.203 inch (13/64 inch) cutting diameter and a 0.625 inch length of cut, this tool handles contour milling, profiling, and finishing passes where a full-radius tip is required. The AlTiN+ coating improves heat resistance and extends tool life in high-temperature cutting environments. Four flutes with a medium flute type provide a balance of chip evacuation and surface finish quality. This end mill is used by machinists and tool-and-die professionals working on CNC mills and machining centers.

This tool is suited for milling ferrous metals, hardened steels, stainless alloys, and similar materials where the AlTiN+ coating delivers thermal and oxidation resistance. The 0.250 inch cylindrical shank fits standard ER and shrink-fit collet toolholders common in CNC machining setups. The 2.5 inch overall length gives adequate reach for most standard cavity and contour work without sacrificing rigidity. No extended reach or chipbreaker geometry is present, making this a straightforward choice for general-purpose ball nose finishing.

Key Features

• 0.203 inch (13/64 inch) ball nose cutting diameter for contour and profile milling
• AlTiN+ coating for elevated heat resistance and longer tool life in ferrous materials
• 4-flute, medium flute geometry balances chip clearance and finish quality
• Solid carbide construction provides rigidity and wear resistance over HSS alternatives
• 0.250 inch cylindrical shank fits standard collet toolholders
• 2.5 inch overall length suits typical CNC cavity and finishing applications

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 0.250 inch cylindrical shank collet or toolholder. No specific machine model compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Ensure the spindle and toolholder are clean and free of chips before seating the shank. Verify collet size matches the 0.250 inch shank diameter before tightening. Never exceed the end mill manufacturer recommended speeds and feeds for the workpiece material and coating type.
