Built from M35 powdered metal high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and improved wear resistance compared to standard HSS tooling. The 1\/8 inch cutting diameter and 3\/8 inch length of cut make it well suited for slotting, profiling, and peripheral milling in tight geometries. The 30-degree helix angle promotes smooth chip evacuation, while the right-hand cut and right-hand spiral flute configuration are standard for most CNC and manual milling setups. This is a single-end, centercutting tool, so it can plunge directly into workpiece material.\u003c\/p\u003e\u003cp\u003eThis end mill is used in machine shops, tool rooms, and production environments where small-diameter precision cutting is required. It fits applications in ferrous and non-ferrous metals where an M35 cobalt-content steel provides the hardness and heat resistance needed at elevated feeds and speeds. The regular length designation and compact 1-7\/8 inch overall length make it a practical choice for close-tolerance work in vertical milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM35 powdered metal high speed steel construction for elevated hardness and heat resistance\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating extends tool life and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand spiral helix promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003e2-flute configuration provides adequate chip clearance in slotting and profiling cuts\u003c\/li\u003e\n\u003cli\u003eOSG Series 673 regular-length design for consistent dimensional repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/16 inch collets or end mill holders on CNC machining centers and manual vertical mills.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a calibrated collet or end mill holder rated for the 3\/16 inch shank diameter to maintain runout tolerances. Verify tool projection and engagement length before initiating a cut to prevent deflection or premature tool failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches (1.875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Mill Material\u003c\/strong\u003e: Powdered Metal High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 673\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: 6737605\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51755764875570,"sku":"6737605","price":43.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b474f03ff46e8e1b04c7938ad8e8dcd.jpg?v=1788959381","url":"https:\/\/voomisupply.com\/products\/osg-6737605-square-end-mill-1-8-in-2-flute-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
