Accupro 95168437 Corner Radius End Mill 1/4 in 5 Flute

Product Description

The ACCUPRO 95168437 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. It features a 1/4 inch diameter, a 3/4 inch length of cut, and a 0.0450 inch corner radius that blends strength with surface finish quality. The five-flute geometry with variable helix reduces chatter and improves chip evacuation at higher feed rates. An AlTiN coating adds heat resistance and hardness for extended tool life in ferrous and high-temp alloy materials. This tool is single-end and centercutting, allowing direct plunge entry into the workpiece. The 1/4 inch shank diameter and 2.5 inch overall length suit standard collet and toolholder setups used in CNC machining centers.

This end mill is suited for finish milling, contouring, and slotting operations in tool and die, aerospace component, and precision part manufacturing. The corner radius reduces stress concentration at the cutting edge, making it a preferred choice when machining hardened steels, stainless alloys, and similar difficult-to-cut materials. Right-hand flute direction and right-hand cutting action are standard for conventional CNC spindle configurations. It is appropriate for both light and moderate depths of cut in production and job-shop environments.

Key Features

• 0.0450 inch corner radius for improved edge strength and surface finish
• 5-flute design with variable helix reduces vibration and improves material removal rates
• AlTiN coating provides high heat and wear resistance for extended tool life in ferrous alloys
• Centercutting geometry allows plunge milling directly into the workpiece
• Micrograin solid carbide substrate for rigidity and dimensional stability
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills using 1/4 inch collets or toolholders with a 1/4 inch bore.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the 1/4 inch shank in a matched collet or end mill holder to the manufacturer-specified clamping torque range for that holder type. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
