Promax 120-01012 Roughing Finishing End Mill Solid Carbide

Product Description

The PROMAX 120-01012 is a solid carbide roughing finishing end mill designed for high-efficiency material removal and finish passes in a single tool. With a 0.1563-inch mill diameter, four flutes, and a 0.01-inch corner radius, this end mill handles both aggressive roughing cuts and smooth finishing operations. The TiCN coating improves wear resistance and reduces friction at the cutting edge. A 40-degree helix angle promotes efficient chip evacuation, making this tool well suited for tight-tolerance work in harder materials. It is a single-end tool with right-hand flute direction and right-hand cutting action.

This end mill is used in CNC milling operations where a small-diameter tool with a corner radius is required. The 0.1563-inch diameter and 0.5-inch length of cut make it a practical choice for slotting, profiling, and pocketing in ferrous and non-ferrous metals. The Weldon flat shank in 3/16 inch provides a secure grip in standard Weldon-style tool holders, reducing pullout risk during roughing passes. Machinists and tool-and-die professionals working in job shop, mold-making, or precision manufacturing environments will find this tool relevant to tight-feature work.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• TiCN coating extends tool life and reduces built-up edge in ferrous materials
• 0.01-inch corner radius blends roughing and finishing capability in one tool
• 40-degree helix angle promotes efficient chip flow and reduces heat buildup
• Weldon flat shank minimizes tool pullout in high-feed applications
• Center-cutting design allows plunge entry without a pre-drilled pilot hole

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC milling machines accepting a 3/16-inch Weldon flat shank end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Power down and lock out the spindle before changing tooling. Seat the Weldon flat fully against the set screw in the tool holder and torque the holder to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as even minor runout will accelerate wear on a small-diameter carbide tool.
