Accupro 95169905 Corner Radius End Mill 3/4 in 4-flute

Product Description

The ACCUPRO 95169905 is a solid carbide corner radius end mill engineered for high-performance milling in demanding machining environments. It features a 3/4 inch diameter with a 0.2500 inch corner radius, four flutes, and an AlCrTiN coating that provides excellent heat resistance and tool life at elevated cutting speeds. The 38-degree variable index helix promotes chip evacuation and reduces chatter during aggressive cuts. At 3 inches overall length with a 7/8 inch length of cut, this single-end mill is sized for a wide range of profiling, slotting, and finishing operations on hard and abrasive workpiece materials.

This end mill is suited for use in CNC machining centers handling ferrous and hardened materials where corner strength and surface finish are critical. The centercutting design allows plunge entry, giving machinists flexibility in toolpath programming. The straight-cylindrical shank at 3/4 inch diameter provides secure clamping in standard ER collet chucks and end mill holders. It is commonly used in tool and die, mold making, and precision part manufacturing across job shops and production floor environments.

Key Features

• AlCrTiN coating for elevated heat resistance and extended tool life in high-speed applications
• Variable index flute spacing reduces harmonic vibration and improves surface finish
• Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Micrograin solid carbide construction delivers rigidity and edge retention in hard materials
• 0.2500 inch corner radius protects edge integrity and reduces stress concentration at corners
• Right-hand cut and right-hand spiral flute direction for compatibility with standard CNC spindle configurations

Compatibility

Designed as an OEM-style replacement or direct-use tool for CNC machining centers and knee mills accepting a 3/4 inch straight-cylindrical shank in standard ER collet or end mill holder tooling systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify shank seating depth meets the tool holder manufacturer minimum engagement specification before tightening. Follow the tool manufacturer and machine builder guidelines for appropriate feeds, speeds, and depth of cut when programming for this tool geometry.
