Sandvik Coromant 8036891 Corner Radius End Mill 1in 5fl

Product Description

The SANDVIK COROMANT 8036891 is a solid carbide corner radius end mill engineered for demanding milling applications in ferrous and hardened materials. It features a 1-inch cutting diameter, a 0.06-inch corner radius, and five flutes with a variable helix and variable index geometry. The AlTiN coating improves heat resistance and tool life at elevated cutting temperatures. This end mill belongs to the CoroMill Dura series and is designed for single-end, center-cutting use in right-hand cutting and right-hand flute configurations. Machinists and tool-and-die professionals use it in CNC vertical and horizontal machining centers.

This tool is suited for finishing and semi-finishing operations in steel, stainless steel, and hardened alloys where corner integrity and surface finish matter. The 1.5-inch length of cut and 4-inch overall length make it appropriate for moderate-depth pocketing, contouring, and profile milling. The straight-cylindrical shank with 1-inch diameter fits standard ER and hydraulic toolholders used in production and job-shop environments. It is classified under material grade X1BH, indicating suitability for hard and difficult-to-machine workpiece materials.

Key Features

• 1-inch cutting diameter with 0.06-inch corner radius for controlled edge blending
• 5-flute variable helix and variable index design reduces chatter and improves surface finish
• AlTiN coating provides thermal resistance for dry or near-dry machining in hard materials
• Center-cutting geometry allows plunge entry and ramping operations
• Solid carbide construction delivers rigidity and wear resistance in high-speed applications
• CoroMill Dura series, material grade X1BH, for hard and abrasive workpiece materials

Compatibility

Designed as an OEM replacement-style solid carbide end mill compatible with standard 1-inch straight-cylindrical toolholders including ER collet chucks, hydraulic chucks, and shrink-fit holders used in CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the toolholder bore and collet are clean and free of chips before seating the shank to the recommended gauge-line depth. Confirm runout with a dial indicator before cutting, as excessive runout accelerates edge wear on carbide end mills. Follow the machine tool manufacturer torque specifications for drawbar and collet nut tightening.
