Constructed from high speed steel (HSS) with a titanium nitride (TiN) coating, it offers improved surface hardness and wear resistance compared to uncoated HSS tooling. The cutter measures 1\/8 inch in diameter with a 3\/8 inch length of cut and a 2-5\/16 inch overall length. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation and a smooth cutting action. This end mill is center-cutting, allowing it to plunge directly into material as well as profile and slot.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for light-duty milling operations on ferrous and non-ferrous metals, plastics, and composites in job shop, toolroom, and maintenance machining environments. The 3\/8 inch shank diameter fits standard collet chucks and end mill holders on manual knee mills, CNC machining centers, and benchtop milling machines. Right-hand cut and right-hand flute geometry make it compatible with conventional right-hand spindle setups. The regular length classification positions it for general-purpose work where extended reach is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiN coating increases surface hardness and extends tool life compared to bare HSS\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry into material\u003c\/li\u003e\n  \u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle setups\u003c\/li\u003e\n  \u003cli\u003eRegular length classification for general-purpose slotting and profiling\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch shank fits common collet and end mill holder systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock end mill for use in any milling machine or machining center equipped with a collet chuck or end mill holder accepting a 3\/8 inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder to the recommended minimum engagement depth before tightening. Verify runout with a dial indicator after clamping, as excessive runout accelerates wear and reduces cut quality on a small-diameter tool like this one.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: 2-5\/16 inches (2.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: -20550-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691842306354,"sku":"-20550-2","price":27.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe8cfba86a1b3f1d5d52527e93861623.jpg?v=1788290348","url":"https:\/\/voomisupply.com\/products\/value-collection-20550-2-square-end-mill-1-8-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
