With a 3\/8 inch mill diameter and a 0.015 inch corner radius, it delivers a controlled edge blend that reduces stress concentration at part corners and extends tool life on hard materials. The 4-flute, right-hand spiral geometry supports both roughing and finishing passes in a single setup. At 2.5 inches overall length with a 3\/8 inch straight-cylindrical shank toleranced to h6, this end mill seats securely in standard end mill toolholders. It is suited for use by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for cutting steel, cast iron, superalloys, titanium, stainless steel, and hard materials. The variable helix and variable index geometry help reduce harmonic chatter during aggressive cuts, making it effective in high-speed machining centers and manual mills alike. It is a centercutting design, allowing plunge entry into the workpiece. The Series 1030 designation places it in a standard-reach, straight-shank family intended for use with conventional end mill toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.015 inch corner radius reduces edge chipping and stress concentration on finished part corners\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry suppress chatter during roughing and finishing cuts\u003c\/li\u003e\n\u003cli\u003eSolid carbide submicron-grade material provides rigidity and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute spiral with normal pitch for compatibility with standard CNC toolpaths\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank with h6 tolerance fits standard end mill toolholders with minimal runout\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill toolholders.

Secure the shank in a clean, properly sized collet or toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the corner radius and cutting edges for chips or wear before each use. Coolant-through is not supported on this tool, so verify that flood or mist coolant delivery is directed at the cutting zone externally.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 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: 0.180 inches (22.22 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (63.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1030\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GWS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 119337\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":51971331686706,"sku":"119337","price":131.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36537447236c65b4546837f96df8cf93_e853178f-ea21-4650-a4c0-cb14410259ef.jpg?v=1789955611","url":"https:\/\/voomisupply.com\/products\/gws-119337-corner-radius-end-mill-3-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
