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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePowdered metal construction for improved toughness and edge retention versus standard HSS\u003c\/li\u003e\n\u003cli\u003e3-flute spiral geometry with 50-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for applications requiring periodic re-sharpening\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration; OSG Series 660 designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned 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.

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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 50 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 660\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6601100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732956610866,"sku":"6601100","price":125.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bcd0cdff15a6d02a93c1a74782f9aee.jpg?v=1788749530","url":"https:\/\/voomisupply.com\/products\/osg-6601100-square-end-mill-0-5-in-3-flute-powdered-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
