Osg 36700111 Corner Radius End Mill 1/16 in 4 Flute Carbide

Product Description

The OSG 36700111 is a solid carbide corner radius end mill designed for precision milling in demanding material applications. It features a 1/16 inch (0.0625 inch) cutting diameter with a 0.01 inch corner radius, 3/16 inch length of cut, and a 4-flute, single-end configuration. The tool is coated with OSG WXL finish applied via PVD process, which improves wear resistance and heat dissipation during high-speed cutting. With a 30-degree medium helix and centercutting capability, it supports both plunge entry and lateral passes. Machinists and tool-and-die professionals install this end mill in standard toolholders on CNC mills and machining centers.

This end mill is suited for finish and roughing operations across a wide range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its micrograin carbide substrate handles the elevated cutting forces and temperatures common in these applications. The 1/8 inch straight-cylindrical shank fits standard collet and toolholder systems, making it a practical choice for production shops, mold and die work, and precision component machining where tight corner geometry control is required.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention in hard and abrasive materials
• WXL PVD coating reduces friction and extends tool life in steel, stainless, and superalloy cuts
• 0.01 inch corner radius minimizes stress concentration at the cutting edge and improves part surface finish
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Right-hand cut, right-hand flute direction with normal pitch and helical flute geometry for efficient chip evacuation
• Single-end configuration with 1-1/2 inch overall length fits compact toolholder setups

Compatibility

Designed for use with standard collet-style toolholders accepting a 1/8 inch straight-cylindrical shank. Suitable for CNC milling applications in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials per OSG Series 3670 application guidelines.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The tool must be seated fully and evenly in a clean, properly sized collet or toolholder to the manufacturer-specified engagement depth before tightening. Verify spindle runout is within acceptable limits prior to cutting, as excess runout will accelerate edge wear on small-diameter end mills. Always confirm machine is at a full stop and spindle lock is engaged before changing tooling.
