Promax US007002 Corner Radius End Mill 1/8 in 4 Flute

Product Description

The PROMAX US007002 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. Built from micrograin carbide and coated with PROMAX PowerLayer, it delivers durability and wear resistance across a range of workpiece materials. The 1/8 inch mill diameter and 0.0100 inch corner radius make it well-suited for finishing and roughing operations where edge integrity matters. With 4 flutes, a variable helix, and variable index geometry, it reduces chatter and improves chip evacuation in tight-tolerance cuts. This tool is single-end, center-cutting, and features right-hand flute direction with right-hand cutting.

The US007002 is intended for use in CNC machining centers and milling machines where precision small-diameter work is required. It is a stub-length tool with a 1/4 inch length of cut and a 1-1/2 inch overall length, making it appropriate for applications where rigidity and minimal deflection are priorities. It is compatible with standard straight-cylindrical toolholders and is commonly used by machinists working on steel, stainless steel, cast iron, superalloys, titanium, and non-ferrous metal components. No coolant-through capability is present, so external coolant or air blast is typical in production use.

Key Features

• Micrograin solid carbide construction for high hardness and wear resistance
• PROMAX PowerLayer coating optimized for steel, stainless, cast iron, superalloys, titanium, and non-ferrous metals
• Variable helix and variable index geometry reduce vibration and chatter
• Center-cutting design allows plunge entry
• Coarse pitch, spiral flute, stub-length configuration for rigidity in small-diameter applications
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed for use with straight-cylindrical toolholders. Suitable for milling steel, stainless steel, cast iron, superalloys, titanium, and non-ferrous metals. Part of the PROMAX Series US007.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Ensure the shank is fully seated and clean before clamping to avoid runout errors. Confirm spindle direction matches the right-hand cutting geometry before initiating a cut. Inspect the cutting edge for chips or coating damage before each use, as small-diameter carbide tools are sensitive to improper handling.
