Osg 36700611 Corner Radius End Mill 1/8 in 4 Flute Carbide

Product Description

The OSG 36700611 is a solid carbide corner radius end mill designed for precision milling in demanding machining environments. With a 1/8 inch (0.1250 inch) mill diameter and a 0.02 inch corner radius, this single-end tool generates a controlled radius at the cutting edge to reduce stress concentrations and extend tool life in both roughing and finishing operations. The 4-flute, right-hand helical geometry runs at a medium helix angle of 30 degrees and is finished with OSG WXL PVD coating for enhanced wear resistance and heat management. This tool is sold individually and weighs 0.2 pounds.

The OSG 36700611 is suited for machining steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, covering ISO material groups P, M, K, N, S, and H. Its centercutting design allows plunge entry, making it versatile for slot milling, profiling, and pocket work. The regular-length configuration, with a 1/2 inch length of cut and 1-1/2 inch overall length, fits standard toolholder setups commonly found on CNC machining centers and manual mills. The micrograin carbide substrate supports the tight tolerances required in precision component manufacturing.

Key Features

• 0.02 inch corner radius reduces edge chipping and stress concentration at part corners
• WXL PVD coating improves wear resistance across a broad range of workpiece materials
• Centercutting geometry permits direct plunge entry without pre-drilling
• Micrograin solid carbide substrate supports tight mill diameter tolerance of 0.0000 to -0.0008 inches
• Right-hand cut, right-hand flute direction with normal pitch for chip control in both roughing and finishing
• Straight-cylindrical shank with h6 tolerance fits standard precision toolholders

Compatibility

Designed for use with standard toolholders accepting a 1/8 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 or CNC setup technician. Ensure the machine spindle is fully stopped and the tool is secured with the appropriate collet or end mill holder before tightening to the toolholder manufacturer's specification. Confirm runout is within acceptable limits before beginning a cut, as even minor runout on a 1/8 inch diameter tool accelerates wear and risks breakage. Follow shop safety procedures and applicable OSHA machine guarding requirements during tool changes.
