Osg 20220600 Corner Radius End Mill 0.1563in 2 Flute Carbide

Product Description

The OSG 20220600 is a solid carbide corner radius end mill designed for precision milling of non-ferrous metals. The tool measures 0.1563 inches in diameter with a 0.02 inch corner radius and a 1.25 inch length of cut. A 2-flute, right-hand helical flute geometry promotes efficient chip evacuation, while the bright uncoated finish is suited for aluminum, copper, brass, and similar soft or gummy materials. Overall length is 2 inches with a 3/16 inch straight cylindrical shank. This is a single-end, centercutting tool capable of plunge entry and lateral passes. It belongs to OSG Series 2022 and is sized for toolholders accepting a 0.1875 inch shank.

This end mill is used in CNC machining centers and manual milling setups where non-ferrous workpieces require a controlled edge radius to reduce stress concentrations, prevent chipping at pocket corners, or produce a blended floor-to-wall transition. The coarse pitch, medium helix configuration suits roughing operations in aluminum and other non-ferrous alloys. Typical users include machinists and CNC operators working in job shops, aerospace component manufacturing, and general precision fabrication where small-diameter tooling and tight tolerances are standard.

Key Features

• 0.02 inch corner radius reduces stress risers and produces blended inside corners in non-ferrous workpieces
• Solid carbide construction provides rigidity and wear resistance in small-diameter end mills
• 2-flute, right-hand helical geometry supports chip clearance in soft, gummy non-ferrous materials
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Bright uncoated finish is compatible with cutting fluids and recommended for non-ferrous applications where coatings may cause built-up edge
• Straight cylindrical shank with h6 tolerance fits standard collet chucks and end mill holders

Compatibility

Designed for use with standard toolholders accepting a 3/16 inch (0.1875 inch) straight cylindrical shank. Intended for machining non-ferrous metals. No specific machine model compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation is performed by machinists using a collet chuck or end mill holder sized to the 0.1875 inch shank diameter. Confirm the toolholder bore and collet are clean and free of runout before seating the tool. Secure to the manufacturer-specified retention torque for the toolholder type in use. Verify spindle direction is set to right-hand rotation before initiating a cut.
