Accupro 95169796 Corner Radius End Mill 1/4 in 7 Flute

Product Description

The ACCUPRO 95169796 is a solid carbide corner radius end mill designed for precision milling in demanding machining environments. It features a 1/4 inch diameter, a 7-flute geometry, and a 38-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The end mill carries an AlCrTiN coating, which provides high heat resistance and extended tool life in hard and abrasive workpiece materials. With an overall length of 2.5 inches and a length of cut of 0.75 inches, it is sized for short-reach profiling and finishing passes. This is a single-end, non-centercutting tool intended for right-hand cutting and right-hand flute direction.

This end mill is suited for finish milling, contour profiling, and corner blending operations on hardened steels, stainless, and high-temp alloys. The corner radius end geometry reduces stress concentration at the cutting edge and produces a controlled radius at the base of milled features. It is a fit for CNC machining centers in tool and die, aerospace component, and precision parts manufacturing. The straight-cylindrical shank accepts standard ER or end mill holders sized for 1/4 inch shanks.

Key Features

• Solid carbide micrograin substrate for rigidity and wear resistance
• AlCrTiN coating rated for high-heat cutting in hard and abrasive materials
• 7-flute design increases feed rate capability and improves surface finish
• 38-degree helix angle promotes efficient chip flow and reduced cutting forces
• Corner radius end type protects the cutting edge and blends floor-to-wall transitions
• Right-hand cut, right-hand spiral, single end configuration

Compatibility

Designed as a direct-fit replacement for Series HS corner radius end mills with a 1/4 inch straight-cylindrical shank compatible with standard ER collet chucks and end mill holders sized for 1/4 inch bore.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates edge wear on multi-flute carbide tools.
