Promax US007006 Corner Radius End Mill 1/8 Inch 4 Flute

Product Description

The PROMAX US007006 is a solid carbide corner radius end mill designed for high-performance milling in demanding industrial and machining applications. Built on the Series US007 platform, it features a 1/8 inch (0.1250 inch) shank diameter, a 1/2 inch mill diameter, and a 0.5 inch length of cut with an overall length of 2.5 inches. The end mill carries a PROMAX PowerLayer coating and a variable helix, variable index geometry that reduces chatter and improves surface finish. It is rated for both roughing and finishing operations, making it a versatile single-tool solution for machinists working across a broad range of materials.

This end mill is suited for use in CNC machining centers, vertical mills, and similar toolholding setups where a straight-cylindrical shank is compatible. Its primary workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and non-ferrous metals. The corner radius geometry extends tool life at the cutting edge and reduces chipping in interrupted cuts. The stub length classification and center-cutting design allow for plunge entry and slot milling where clearance is limited.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance
• PROMAX PowerLayer coating for extended tool life across ferrous and non-ferrous materials
• Variable helix and variable index geometry reduces vibration and chatter
• Corner radius of 0.0300 inches with a tight tolerance of -0.0010 to 0.0010 inches
• Center-cutting and right-hand flute direction supports plunge and climb milling
• Rated for both roughing and finishing in a single tool

Compatibility

Designed for use with standard toolholders accepting a 1/8 inch straight-cylindrical shank. Compatible workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and non-ferrous metals as designated by material codes P, M, K, S, and N.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the toolholder collet or end mill holder is clean and within spec before seating the shank. Power down and lock out the spindle before changing tooling. Verify runout after clamping and confirm feeds and speeds are set appropriately for the workpiece material and depth of cut before initiating a cut.
