Osg 36701611 Corner Radius End Mill 1/4 in 4 Flute Carbide

Product Description

The OSG 36701611 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. Built to Series 3670 standards, it features a 1/4 inch diameter, a 0.045 inch corner radius, and a WXL PVD coating that extends tool life across a wide range of workpiece materials. The 4-flute, right-hand helical geometry supports both roughing and finishing in a single tool, making it a practical choice for machinists running production or job-shop work on CNC machining centers and manual mills with appropriate toolholders.

This end mill is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The single-end, centercutting design allows plunge entry and lateral cutting in the same operation. With a regular-length flute and straight cylindrical shank, it fits standard collet chucks and end mill holders. It is appropriate for both roughing passes and finish profiling where a controlled corner radius is required to reduce stress concentrations in part geometry.

Key Features

• 0.045 inch corner radius reduces stress concentration and improves surface finish at part edges
• WXL PVD coating enhances wear resistance across steel, stainless steel, cast iron, non-ferrous metals, superalloys, and hard materials
• Solid micrograin carbide construction provides rigidity and edge retention
• Centercutting design permits plunge milling and slot entry
• 4-flute right-hand helical geometry supports both roughing and finishing material removal
• Straight cylindrical shank with h6 tolerance fits standard collet chucks and toolholders

Compatibility

Designed for use with standard end mill toolholders and collet chucks accepting a 1/4 inch straight cylindrical shank. Suitable for CNC machining centers and manual mills running steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before changing tooling. Verify runout with a dial indicator after seating the shank in the toolholder to confirm proper clamping. Do not exceed the tool's rated depth of cut or feed parameters for the workpiece material being machined.
