Sandvik Coromant 8036178 Corner Radius End Mill 1/4 in

Product Description

The SANDVIK COROMANT 8036178 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. Built to the CoroMill Dura series standard, this single-end tool features a 1/4 inch diameter, a 0.03 inch corner radius, and four flutes with a variable helix and variable index geometry. The AlTiN coating improves heat resistance and tool life in demanding cutting conditions. It is centercutting and right-hand cutting, making it suitable for plunge entry and conventional milling passes. Machinists and CNC operators working in job shops, aerospace, automotive, and general manufacturing will find this tool appropriate for finishing and semi-finishing operations in hard and abrasive materials.

This end mill is used in CNC machining centers and manual milling machines where tight corner radii and smooth surface finishes are required. The 5/8 inch length of cut and 2-1/2 inch overall length suit a range of pocket milling, contouring, and profiling applications. The straight cylindrical shank with a 1/4 inch diameter fits standard collet chucks and end mill holders. It is rated under material grade X1BH, indicating suitability for harder workpiece materials. This tool is appropriate for dry or minimum quantity lubrication cutting strategies when paired with appropriate spindle speeds and feed rates for the material being cut.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for elevated heat resistance and extended tool life
• Variable helix and variable index geometry reduces chatter and vibration
• Centercutting design allows direct plunge entry into workpieces
• 0.03 inch corner radius reduces stress concentration at cutting edges and improves corner durability
• Right-hand flute direction and cutting action compatible with standard CNC spindle configurations

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 1/4 inch collet chucks, end mill holders, and shrink-fit toolholders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the collet or holder and torque the clamping nut or set screw to the toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use, as carbide tooling is brittle and should not be used if the edge is compromised.
