Osg 37710013 Corner Radius End Mill 8mm 4 Flute Carbide

Product Description

The OSG 37710013 is a solid carbide corner radius end mill designed for precision milling across a wide range of workpiece materials. It features an 8 mm cutting diameter with a 0.5 mm corner radius, a 19 mm length of cut, and a 100 mm overall length. The 4-flute, single-end geometry with a medium helix and right-hand cutting direction suits both roughing and finishing operations. An 8 mm straight-cylindrical shank with h6 tolerance ensures consistent tool holding in standard toolholders. The WXL PVD coating extends tool life in demanding applications involving steel, stainless steel, cast iron, and hard materials.

This end mill is suited for use in CNC machining centers and manual mills where a corner radius profile is required to reduce stress concentrations at workpiece edges or to produce radiused floor-to-wall transitions. It performs across a broad material range including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The centercutting design allows plunge entry, adding flexibility to the toolpath. It is appropriate for shop environments handling general production and high-mix low-volume work in these material categories.

Key Features

• 0.5 mm corner radius reduces edge chipping and stress concentrations in the workpiece
• WXL PVD coating provides wear resistance across steel, stainless, cast iron, non-ferrous, superalloys, and hard materials
• Centercutting geometry enables direct plunge entry without a pre-drilled hole
• 4-flute helical design supports both roughing and finishing in a single tool
• Straight-cylindrical shank with h6 shank diameter tolerance for precise toolholder fitment
• Normal pitch, no chipbreaker, no coolant-through — suited for external coolant or dry machining setups

Compatibility

Designed for use with standard cylindrical toolholders accepting an 8 mm straight shank. Compatible with CNC machining centers and manual mills using collet chucks, end mill holders, or shrink-fit holders sized for 8 mm shanks.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the toolholder and spindle are clean and free of debris before seating the shank to the recommended gauge length. Confirm runout with a dial indicator after clamping, as excessive runout accelerates wear on corner radius tools. Follow the machine builder and toolholder manufacturer torque specifications for the clamping mechanism used.
