Promax US007113 Corner Radius End Mill 0.75 in 4 Flute

Product Description

The PROMAX US007113 is a single-end, corner radius end mill designed for high-performance material removal in demanding machining applications. Built from micrograin solid carbide and finished with PROMAX PowerLayer coating, this tool handles both roughing and finishing operations in a single setup. It carries a 0.75 inch mill diameter, a 0.030 inch corner radius, and a 2.0 inch length of cut, with an overall length of 2.5 inches. The 4-flute, right-hand spiral geometry with variable helix and variable index delivers improved chip evacuation and reduced chatter at the cutting edge. Centercutting capability allows for direct plunge entry into the workpiece.

This end mill is suited for use in CNC machining centers handling steel, stainless steel, cast iron, superalloys, titanium, and non-ferrous metals. Its stub-length configuration and straight cylindrical shank at 0.5 inch diameter make it compatible with standard collet-style and hydraulic toolholders. The coarse pitch and variable helix design make it well-suited for high-speed roughing passes as well as finish profiling, reducing the need for separate tool changes between operations. It is intended for use by professional machinists and tool-and-die shops working with medium to hard workpiece materials.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous cutting
• PROMAX PowerLayer coating reduces friction and extends tool life across a wide material range
• Variable helix and variable index geometry minimizes harmonic vibration and chatter during cuts
• 0.030 inch corner radius protects the cutting edge and reduces stress concentration at the tool tip
• Centercutting design allows direct plunge milling without a pilot hole
• Single-end stub configuration with straight cylindrical shank fits standard toolholder setups

Compatibility

Designed for use with standard collet, hydraulic, and shrink-fit toolholders accepting a 0.5 inch straight cylindrical shank. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and non-ferrous metals per material codes P, M, K, S, and N.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully within the toolholder to the recommended gauge line depth before tightening to prevent runout. Verify spindle direction is set to right-hand rotation before engaging the cut. Do not exceed the rated depth of cut or feed rate for the workpiece material and machine setup.
