Promax 119-01026 Corner Radius End Mill 0.1563 in Carbide

Product Description

The PROMAX 119-01026 is a solid carbide corner radius end mill designed for high-performance roughing and finishing operations in a single tool. With a 0.1563-inch cutting diameter and a 0.01-inch corner radius, this end mill delivers smooth surface finishes while reducing chipping at the cutting edge. The ZrN (zirconium nitride) coating improves wear resistance and reduces friction during cuts. Three flutes with a 40-degree right-hand helix provide efficient chip evacuation and clean material removal. This is a centercutting, single-end design suited for tight-tolerance machining work in both conventional and CNC milling applications.

This end mill is built for precision milling in applications requiring fine detail work at small diameters. The stub-length configuration and straight-cylindrical shank keep runout low and improve rigidity in close-quarters cuts. It is a practical choice for mold work, die machining, and profiling operations where both a smooth floor radius and controlled wall geometry are required. Licensed machinists and CNC operators working in job shops, tool rooms, and production environments will find this tool suited for non-ferrous metals, hardened steels, and similar materials where micrograin carbide performs reliably.

Key Features

• Solid micrograin carbide construction for extended tool life in demanding cuts
• ZrN coating reduces friction and improves wear resistance without adding excessive edge thickness
• 0.01-inch corner radius reduces stress concentration and improves surface finish at the floor-wall junction
• 3-flute, 40-degree helix geometry balances chip clearance with cutting stability at small diameters
• Centercutting design allows plunge entry and ramping operations
• Straight-cylindrical shank with tight diameter tolerance supports secure collet holding

Compatibility

Designed as an OEM-style replacement or direct-fit option for standard 3/16-inch shank collets and tool holders used in CNC milling machines and manual mills accepting straight-cylindrical shanks.

Installation Notes

Installation is performed by qualified machinists or CNC operators following standard tooling procedures. Secure the straight-cylindrical shank in a clean, properly sized collet or end mill holder and torque to the tool holder specification. Ensure the spindle and machine are fully powered down before changing tooling. Verify runout with a dial indicator before beginning cuts to protect both the tool and the workpiece.
