Osg 6601100 Square End Mill 0.5 in 3 Flute Powdered Metal

Product Description

The OSG 6601100 is a single-end square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. It features a 0.5 inch cutting diameter, a 1.25 inch length of cut, and a 0.5 inch shank diameter, with an overall length of 3.25 inches. Manufactured from powdered metal, this tool offers improved toughness and wear resistance compared to standard high-speed steel. The 3-flute, spiral-flute geometry with a 50-degree helix angle promotes efficient chip evacuation and smooth cutting action. The uncoated finish suits applications where coating is not required or where re-sharpening is anticipated. This end mill is intended for use by machinists and tooling professionals in CNC and manual milling environments.

The OSG 6601100 is suited for slotting, profiling, and peripheral milling in a range of shop and production settings. Its regular-length configuration makes it a practical choice for standard-depth cuts in both job shop and light production environments. The centercutting capability allows plunge entry directly into the workpiece without a pre-drilled hole, adding flexibility to machining routines. Right-hand cut and right-hand flute orientation follow the most common spindle and fixture configurations found in vertical machining centers and knee mills.

Key Features

• Powdered metal construction for improved toughness and edge retention versus standard HSS
• 3-flute spiral geometry with 50-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge milling without pre-drilling
• Uncoated finish suitable for applications requiring periodic re-sharpening
• Right-hand cut and right-hand flute for standard spindle compatibility
• Single-end configuration; OSG Series 660 designation

Compatibility

Designed as an OEM-style replacement or direct-use tooling for milling applications requiring a 0.5 inch diameter, 3-flute square end mill with a 0.5 inch straight shank. Compatible with standard ER and straight-shank collet systems accepting a 0.5 inch shank.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank in a properly sized collet chuck or end mill holder, ensuring the tool is seated to the recommended grip length for the holder type in use. Confirm spindle speed and feed rate are set per the material being machined before engaging the cut. Inspect the tool edge and runout prior to each use; discard or re-sharpen if chipping or excessive wear is detected.
