Accupro 95168460 Corner Radius End Mill 5/16 in 4 Flute

Product Description

The ACCUPRO 95168460 is a solid carbide corner radius end mill designed for precision milling in metalworking applications. It features a 5/16 inch (0.3125 inches) cutting diameter with a 0.0200 inch corner radius, a 4-flute configuration, and an AlTiN coating for extended tool life in high-heat cutting environments. The overall length is 4 inches, with a length of cut of 7/16 inch (0.4375 inches) and a matching 5/16 inch shank diameter. This is a single-end, centercutting tool with right-hand flute direction and right-hand cutting direction, suited for machinists running CNC mills and manual vertical mills on ferrous and non-ferrous materials.

This end mill is suited for finishing and semi-finishing operations where a controlled corner radius is required to reduce stress concentrations in milled pockets, slots, and contours. The extended reach design, with a reach length of 2-1/8 inches (2.1250 inches) and a neck diameter of 0.2813 inches, allows access to deeper features without sacrificing rigidity. It is typically used in job shops and production environments machining steel, stainless steel, cast iron, and similar materials where AlTiN coating performance is most effective.

Key Features

• 0.0200 inch corner radius reduces stress risers in milled profiles
• AlTiN coating provides oxidation resistance and hardness at elevated cutting temperatures
• Solid micrograin carbide construction for wear resistance and dimensional stability
• Centercutting design allows plunge entry into workpiece material
• Extended reach with 2.1250 inch reach length and 0.2813 inch neck diameter for deep-feature access
• Right-hand spiral flutes with regular length classification for standard milling setups

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for CNC machining centers and manual mills accepting a 5/16 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Seat the shank fully in the collet or holder to the minimum insertion depth recommended by the toolholder manufacturer, and verify runout with a dial indicator before engaging the workpiece. Do not exceed the tool's rated cutting parameters for the workpiece material and coating type.
