Accupro 72036809 Corner Radius End Mill 1/2 in 6 Flute

Product Description

The ACCUPRO 72036809 is a solid carbide corner radius end mill designed for high-performance milling in demanding applications. Built with a 0.5000-inch (1/2 inch) mill diameter and a 0.2500-inch corner radius, this single-end tool features 6 flutes and an AlTiN+ coating that provides thermal resistance and extended tool life at elevated cutting temperatures. The variable helix and variable index geometry reduce harmonic chatter, improving surface finish and dimensional accuracy. It is installed by CNC machinists and tool-and-die professionals in production and job-shop environments.

The 72036809 is engineered primarily for cutting high-temperature alloys (material code S), including nickel-based superalloys, titanium, and cobalt-chrome materials common in aerospace, medical device, and power generation component machining. With a 1.2500-inch length of cut and a 3.000-inch overall length, it suits deep-pocket and side-wall milling operations on vertical and horizontal machining centers. The 1/2-inch shank diameter fits standard ER and end mill holder tooling commonly found in production CNC setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN+ coating provides oxidation resistance and hardness at high cutting temperatures
• Variable helix and variable index design reduce chatter and improve surface finish
• 0.2500-inch corner radius protects the cutting edge and reduces stress concentrations at corners
• 6-flute configuration supports higher feed rates and better chip evacuation in finishing cuts
• Center-cutting capable, allowing plunge entry into the workpiece

Compatibility

Designed for use in CNC machining centers with standard 1/2-inch end mill holders or ER collet systems. Optimized for high-temperature alloy workpieces as the primary material application per ACCUPRO Series HS specifications.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank to the minimum recommended engagement depth in the tool holder and torque the retention hardware per the holder manufacturer's specifications. Inspect the cutting edges and coating for damage before each use; do not run a chipped or delaminated carbide tool at full parameters.
