Accupro 95168696 Corner Radius End Mill 1/2 in 5 Flute

Product Description

The ACCUPRO 95168696 is a solid carbide corner radius end mill designed for precision milling of ferrous metals, hardened steels, and high-temp alloys. It measures 0.5000 inches in diameter with a 1.2500-inch length of cut, a 3.0000-inch overall length, and a 0.0200-inch corner radius. The five-flute geometry and variable helix angle reduce chatter and improve chip evacuation at higher feed rates. An AlTiN coating extends tool life in dry and semi-dry cutting conditions by increasing surface hardness and heat resistance. This end mill is a single-end, centercutting tool, meaning it can be used for plunge cuts and slot milling as well as peripheral profiling.

This end mill is suited for CNC machining centers and manual mills performing finishing and semi-finishing passes on ferrous and non-ferrous workpieces. The right-hand spiral flute direction and right-hand cutting direction make it compatible with standard spindle configurations. The 0.5000-inch shank diameter fits standard ER and side-lock toolholders. Typical applications include 3D profiling, pocket milling, and contour work where a radius corner is required to reduce stress concentration or meet part geometry tolerances.

Key Features

• 0.0200-inch corner radius reduces stress risers in milled features and extends part fatigue life
• Five-flute design increases material removal rate compared to four-flute equivalents at equivalent chip load
• Variable helix angle minimizes harmonic chatter during deep-wall profiling
• AlTiN coating provides high heat resistance for dry and near-dry cutting of hardened and abrasive materials
• Centercutting geometry allows direct plunge entry without pre-drilled pilot holes
• Micrograin solid carbide substrate delivers edge sharpness and wear resistance across the full length of cut

Compatibility

Designed as an OEM-style replacement or direct-specification solid carbide corner radius end mill for CNC machining centers and manual milling machines accepting a 0.5000-inch shank diameter toolholder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank to the specified minimum engagement depth in the toolholder and torque the retention mechanism per the toolholder manufacturer's guidelines. Inspect the collet or chuck for runout before first use, as excessive runout accelerates flute wear and can cause premature tool failure. Never exceed the tool's rated depth of cut or feed rate for the workpiece material being machined.
