Accupro 95170085 Corner Radius End Mill 5/8 in 4 Flute

Product Description

The ACCUPRO 95170085 is a solid carbide corner radius end mill designed for high-performance milling operations in demanding shop environments. It features a 5/8 inch diameter with a 3-1/4 inch length of cut and a 6 inch overall length, making it well-suited for deep-reach profiling, slotting, and peripheral milling. The four-flute, right-hand spiral geometry runs with a variable index configuration and a 38-degree helix angle to reduce chatter and improve chip evacuation. An AlCrTiN coating provides heat and wear resistance at elevated cutting temperatures. The 0.120 inch corner radius protects the cutting edge and produces a controlled blend radius on finished surfaces. Installed by machinists and toolroom professionals on CNC machining centers and manual mills.

This end mill is suited for roughing and finishing operations on hardened steels, stainless steels, high-temperature alloys, and similar difficult-to-machine materials where coating performance and edge geometry are critical. The centercutting design allows plunge entry, adding flexibility for pocketing operations. The straight cylindrical shank at 5/8 inch diameter fits standard ER collet chucks and end mill holders commonly found in production and job-shop environments. Single-end configuration means the tool is replaced rather than flipped when the cutting end is worn. The micrograin carbide substrate provides the toughness and rigidity needed for aggressive metal removal rates.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlCrTiN coating for elevated-temperature cutting and extended tool life
• 4-flute, variable index geometry reduces harmonic vibration and chatter
• 0.120 inch corner radius protects edge and blends part geometry
• Centercutting design allows direct plunge entry for pocketing
• 38-degree right-hand helix promotes efficient chip evacuation in deep cuts

Compatibility

Designed for use with standard 5/8 inch straight-bore end mill holders and ER collet chucks. Suitable for CNC machining centers and manual mills configured for right-hand cutting rotation.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and power is locked out before seating or removing the tool from its holder. Clean the shank and holder bore before assembly to prevent runout. Follow the machine tool manufacturer and holder manufacturer guidelines for proper clamping torque and tool projection length.
