Built to Series 3099 standards, this single-end tool features a 0.5-inch diameter, a 0.625-inch length of cut, and a 2.5-inch overall length with a stub-length profile. The FIREX finish provides elevated hardness and heat resistance to extend tool life at higher cutting speeds. A variable helix geometry, with angles ranging between 35 and 38 degrees, reduces chatter and harmonics during cutting. This tool is configured for right-hand cutting and right-hand spiral flutes, and it is centercutting-capable for direct plunge entry.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling cast iron, steel, stainless steel, and hard materials in both production and job-shop environments. The stub-length configuration improves rigidity in tight setups where tool deflection is a concern. The Weldon flat shank provides positive drive engagement in side-lock holders, making it appropriate for high-feed roughing and finishing passes on CNC machining centers. It is commonly installed by machinists and tooling specialists working on ferrous and high-alloy workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eFIREX coating improves thermal and oxidation resistance at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eVariable helix angles of 35 and 38 degrees reduce harmonic vibration and improve surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive rotational drive in side-lock toolholders\u003c\/li\u003e\n  \u003cli\u003eStub-length profile maximizes stiffness and minimizes deflection in short-reach setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for primary use in cast iron and steel workpieces, with secondary suitability for hard materials, stainless steel, and high-temperature alloys per material codes K, P, H, M, and S.

Secure the Weldon flat in a properly torqued side-lock holder per the toolholder manufacturer specification to prevent slippage under load. Verify runout at the cutting edge before first use, as excess runout accelerates uneven flute wear on carbide tooling. Coolant-through is not supported on this tool; flood or mist coolant should be directed at the cutting zone externally.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 to 38 degrees (variable)\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\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3099\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9030990127000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730106057010,"sku":"9030990127000","price":123.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52a22dd372cec081e9cbb6c556704345.jpg?v=1788711821","url":"https:\/\/voomisupply.com\/products\/guhring-9030990127000-square-end-mill-0-5in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
