Ingersoll Cutting Tools 5812863 Corner Radius End Mill Head

Product Description

The INGERSOLL CUTTING TOOLS 5812863 is a solid carbide corner radius end mill head designed for high-performance milling operations in demanding metalworking applications. Built to a 1.0 inch diameter with a 0.031 inch corner radius, this four-flute head features a TiAlN coating that extends tool life under high heat and cutting loads. The helical flute geometry and 38-degree maximum helix angle promote smooth chip evacuation and stable cutting action. Center-cutting capability allows plunge entry without a pre-drilled hole, adding flexibility to complex machining routines. This head is suited for machinists and tool-and-die professionals working on milling machines and machining centers.

This end mill head is used in precision milling applications where a controlled corner radius profile is required to reduce stress concentrations and improve surface finish at part edges. It is well suited for profiling, contouring, and pocket milling in ferrous and hardened materials. The T15 connection type mates with compatible modular tooling systems. With an overall length of 1.45 inches and a length of cut of 0.88 inches, it fits standard modular head adapters used in CNC vertical and horizontal machining centers in both job shop and production environments.

Key Features

• Solid carbide construction in material grade IN2005 for rigidity and wear resistance
• TiAlN coating provides thermal protection and extended tool life in ferrous materials
• Four helical flutes with 38-degree maximum helix angle for smooth chip flow
• 0.031 inch corner radius reduces edge chipping and improves part surface finish
• Center-cutting design allows direct plunge entry
• T15 modular connection for repeatable, secure mounting in compatible tooling systems

Compatibility

Designed for use with modular tooling systems accepting a T15 connection type. Verify adapter and collet compatibility with the specific machine spindle and toolholder before installation.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's torque and seating procedures. Power down and lock out the machine spindle before changing or seating the end mill head. Confirm the T15 interface is clean and free of chips or debris before threading the head into the adapter. Coolant-through is not supported on this head; configure machine coolant delivery accordingly.
