Sandvik Coromant 8035569 Corner Radius End Mill 4.78mm 3 Flute

Product Description

The SANDVIK COROMANT 8035569 is a solid carbide corner radius end mill from the CoroMill Dura series, designed for high-performance milling in demanding metal-cutting applications. It measures 4.78 mm (0.188 inches) in diameter with a 1.5 inch overall length and features a 0.013 inch corner radius that reduces stress concentration at the cutting edge. The AlTiN coating provides elevated heat resistance and extended tool life in dry or semi-dry cutting conditions. With three flutes, variable helix, and variable index geometry, this end mill is suited to finishing and semi-finishing passes where surface quality and dimensional accuracy are priorities. Machinists and tool-room operators handling precision components will find this a reliable choice for steel and hardened alloy work.

This end mill is appropriate for CNC machining centers handling tight-tolerance work in aerospace, die and mold, and general precision manufacturing environments. The centercutting design allows plunge entry, giving the operator flexibility in toolpath programming. The straight cylindrical shank at 0.188 inches fits standard collet chucks and shrink-fit holders common to vertical and horizontal machining centers. Right-hand cutting direction and right-hand spiral flutes are compatible with standard spindle configurations. The CoroMill Dura series material grade X1BH is positioned for use on a range of ferrous and hardened materials where wear resistance and edge integrity are critical.

Key Features

• Solid carbide construction in CoroMill Dura series material grade X1BH for rigidity and wear resistance
• AlTiN coating for high-temperature performance in dry and semi-dry cutting environments
• Variable helix and variable index geometry to reduce harmonic chatter during milling
• 0.013 inch corner radius reduces edge chipping and improves surface finish at part corners
• Centercutting capability allows direct plunge entry without pre-drilling
• Straight cylindrical shank at 0.188 inches for broad collet and holder compatibility

Compatibility

Designed as an OEM-specification solid carbide end mill for use in standard CNC machining center collet chucks, shrink-fit holders, and hydraulic holders accepting a 0.188 inch straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician following the machine tool manufacturer's tool-change procedure. Ensure the spindle is fully stopped and the machine is in a safe state before mounting or removing the end mill. Verify holder runout with a dial indicator before cutting to protect both the tool and the workpiece. Consult applicable shop safety standards and the machine tool manual for proper clamping torque and tool projection guidelines.
