Accupro 72029549 Corner Radius End Mill 3/4 in 6 Flute

Product Description

The ACCUPRO 72029549 is a 6-flute solid carbide corner radius end mill designed for high-performance milling in demanding material applications. Built with an AlTiN+ coating, this single-end tool handles the elevated cutting temperatures associated with high-temp alloys and other difficult-to-machine materials. It features a variable helix and variable index geometry, which reduces harmonic vibration and chatter during aggressive cuts. The 0.12-inch corner radius protects the cutting edge and improves surface finish at part corners. With a 3/4-inch diameter and 1.25-inch length of cut, this tool suits a range of roughing and finishing operations where edge integrity and heat resistance are critical.

This end mill is intended for use in CNC machining centers and milling applications where the primary workpiece material is high-temp alloy, including nickel-based superalloys and similar S-class materials. It is a single-end, right-hand cut, right-hand flute tool with centercutting capability, allowing plunge entry where the operation requires it. The 3/4-inch shank diameter and 4-inch overall length make it compatible with standard CAT, BT, HSK, and Weldon-style toolholders used in production and job-shop environments. Machinists and CNC operators working aerospace, power generation, and precision manufacturing applications will find this tool suited to their requirements.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-temp alloy cutting
• AlTiN+ coating provides thermal barrier and extended tool life at elevated cutting speeds
• Variable helix and variable index design reduces vibration and improves surface finish
• 0.12-inch corner radius protects cutting edge and reduces stress concentration at corners
• Centercutting capable for direct plunge entry without pre-drilling
• 6-flute configuration supports higher feed rates and improved chip evacuation in finish passes

Compatibility

Designed for use with standard 3/4-inch bore toolholders in CNC milling applications. Primary workpiece material is high-temp alloy (material code S). No specific machine model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the toolholder to the manufacturer-recommended engagement depth and verify runout before cutting. Ensure the spindle and coolant system are fully stopped before changing or inspecting the tool. Follow applicable shop safety procedures and machine builder guidelines when setting tool offsets and cutting parameters.
