Promax 100-06412 Corner Radius End Mill 1 in 5 Flute Carbide

Product Description

The PROMAX 100-06412 is a solid carbide corner radius end mill designed for precision milling operations requiring a controlled edge radius and high surface finish quality. With a 1 inch cutting diameter, a 1-3/4 inch length of cut (LOC), and a corner radius ranging from 0.055 to 0.065 inches, this tool reduces stress concentration at the cutting edge and extends tool life in demanding applications. The 5-flute, right-hand cutting geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN coating provides enhanced hardness and wear resistance for use in ferrous and non-ferrous materials. This end mill is center-cutting and belongs to the PROMAX Series 100 product line.

The 100-06412 is suited for vertical machining centers and CNC milling operations in job shop, die-and-mold, and production environments. The coarse pitch flute spacing and right-hand flute direction make it effective for profiling, contouring, and slotting passes where a corner break or blend radius is required on the finished part. The 1 inch shank diameter matches standard ER and side-lock toolholders common in these setups. A licensed machinist or CNC operator typically selects this tool for finish passes on hardened or medium-hardness workpiece materials.

Key Features

• Corner radius range of 0.055 to 0.065 inches reduces edge chipping and stress risers on finished parts
• 5-flute geometry increases feed rate capability and improves surface finish compared to 4-flute designs
• TiCN coating adds wear resistance and lubricity for extended tool life in ferrous and non-ferrous cuts
• 30-degree helix angle promotes smooth cutting action and effective chip evacuation
• Center-cutting design allows plunge entry without a pre-drilled hole
• Solid carbide construction maintains rigidity and edge integrity at elevated cutting speeds

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills using 1 inch diameter straight-shank toolholders. Compatible with standard ER32, side-lock, and hydraulic chucks accepting a 1 inch shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before inserting or removing the end mill from the toolholder. Seat the shank to the recommended minimum engagement depth for the toolholder type in use. Inspect the cutting edges and coating for chips or wear before each use; a damaged TiCN coating or chipped flute indicates the tool should be replaced before running the next operation.
