Osg 36702911 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The OSG 36702911 is a solid carbide corner radius end mill designed for precision material removal in demanding machining applications. It features a 1/2 inch diameter, a 0.06 inch corner radius, and four right-hand helical flutes with a 30-degree medium helix angle. The cutting edge is 1 inch long and the tool measures 3 inches overall. A WXL PVD coating extends tool life and improves performance across a wide range of workpiece materials. Centercutting geometry allows plunge entry, adding versatility for slotting, profiling, and pocket milling operations. This end mill is used by machinists in job shops, production floors, and tool rooms.

This end mill handles both roughing and finishing passes on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The straight cylindrical shank measures 1/2 inch in diameter with a shank tolerance of h6, making it compatible with standard toolholders used in CNC machining centers and manual mills. The normal pitch and variable-index-free design suit general-purpose material removal where consistent chip evacuation and surface finish are priorities.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard and abrasive materials
• WXL PVD coating reduces friction and heat buildup, extending tool life across steel and superalloy applications
• 0.06 inch corner radius reduces stress concentration at cutting corners and improves surface finish at part edges
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Four right-hand flutes with 30-degree medium helix optimized for chip flow in both roughing and finishing cuts
• No coolant-through requirement simplifies setup in shops without high-pressure coolant systems

Compatibility

Designed for use with standard straight-bore toolholders accepting a 1/2 inch cylindrical shank. Suitable for CNC machining centers and manual mills running steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials under OSG Series 3670.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the end mill. Verify runout at the tool tip after clamping to avoid premature edge wear. Confirm that spindle speed and feed rate are programmed within the tool manufacturer's recommended ranges for the target workpiece material before starting a cut.
