Promax 116-03212 Ball End Mill 0.5 in 4 Flute Solid Carbide

Product Description

The PROMAX 116-03212 is a single-end ball end mill designed for precision milling of high-temperature alloys, stainless steel, and steel. Built from micrograin solid carbide and coated with TiCN, this tool delivers extended wear resistance and thermal stability in demanding cutting environments. The 4-flute, 40-degree right-hand spiral geometry promotes efficient chip evacuation while maintaining a smooth finish. With a 0.5-inch mill diameter and 1.25-inch length of cut, it handles a wide range of contour milling, profiling, and slotting applications. Licensed machinists and CNC operators working in job shops, aerospace, or general fabrication will find this a reliable Series 116 tool.

This end mill is suited for milling operations on high-temperature alloys, stainless steel, and steel in both production and prototype environments. The TiCN coating provides low friction and high surface hardness, making it effective where tool life and finish quality are critical. The 0.5-inch shank diameter mounts securely in standard end mill holders and collet chucks used in vertical and horizontal machining centers.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiCN coating for improved hardness and reduced friction in ferrous and high-temp alloy applications
• 4-flute, 40-degree right-hand helix for efficient chip flow and surface finish
• Ball end geometry for contour milling, 3D profiling, and radius bottom slots
• Single-end design with right-hand cutting direction
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed for use on high-temperature alloys, stainless steel, and steel workpieces. Compatible with standard 0.5-inch end mill holders and collet systems used in CNC vertical and horizontal machining centers.

Installation Notes

This tool should be installed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify the shank is fully seated and properly torqued in the tool holder per the holder manufacturer specifications. Confirm spindle speed, feed rate, and depth of cut are set to values appropriate for the workpiece material and machine capability before engaging the cut.
