Built from 3% vanadium high speed steel, it delivers improved wear resistance compared to standard M2 HSS tooling. The cutter measures 3\/16 inch in diameter with a 7\/16 inch length of cut, a 3\/8 inch shank diameter, and a 2-5\/16 inch overall length. The two-flute spiral configuration with a 30-degree helix angle promotes chip evacuation and reduces cutting resistance. Centercutting geometry allows the tool to plunge directly into the workpiece. Right-hand cut and right-hand flute orientation conform to standard milling setups. No coating is applied, making the tool suitable for regrinding and general shop use.\u003c\/p\u003e\u003cp\u003eThis end mill is used in manual mills, knee mills, and CNC machining centers for slotting, profiling, and plunging cuts. The regular-length body fits standard tool holders and collets sized for a 3\/8 inch shank. Its small diameter makes it well suited for tight-tolerance detail work, keyways, and narrow slots in ferrous and non-ferrous materials. Machinists, tool-and-die makers, and maintenance technicians commonly use this size in both production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3% vanadium high speed steel construction for improved abrasion resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e30-degree helix spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eTwo-flute geometry maximizes chip clearance in slotting and pocket milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle setups\u003c\/li\u003e\n\u003cli\u003eUncoated finish supports easy regrinding and reconditioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard ER, DA, and straight-shank collet systems accepting a 3\/8 inch shank.

Secure the shank fully within the collet or tool holder to the recommended engagement depth before tightening. Confirm spindle speed and feed rate are appropriate for the workpiece material and cut depth before engaging the tool. Inspect the cutting edges for damage or wear before each use and remove the tool from service if chipping or deflection is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/16 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\u003eEnd Mill Material\u003c\/strong\u003e: Vanadium High Speed Steel (3% Vanadium)\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\u003eCoating\u003c\/strong\u003e: Uncoated\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: 573\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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: 5730300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731817103666,"sku":"5730300","price":35.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5671e5ad2667c79f4a09e664cdc0330c.jpg?v=1788735251","url":"https:\/\/voomisupply.com\/products\/osg-5730300-square-end-mill-3-16-in-2-flute-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
