Built to Series 3CR specifications, it features a 3\/8 inch mill diameter, a 1 inch length of cut, and a 0.03 inch corner radius that reduces stress concentration at the cutting edge and extends tool life compared to sharp-corner geometry. The micrograin carbide substrate supports higher cutting speeds and feeds, particularly in ferrous and hard materials. This is a single-end, right-hand cut tool with a helical flute design and a Weldon flat shank for positive drive in end mill holders. Machinists and CNC operators in job shops, tool rooms, and production machining environments are the primary installers and users.\u003c\/p\u003e\u003cp\u003eThe SGS 38249 is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its coarse pitch, 2-flute configuration provides good chip clearance in tougher workpiece materials where chip packing is a concern. The 30-degree medium helix balances cutting pressure and surface finish across this range of materials. It is appropriate for roughing material removal operations in both vertical machining centers and manual knee mills using standard end mill holders with Weldon flat retention.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03 inch corner radius reduces edge chipping and workpiece stress risers in roughing passes\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction supports aggressive feeds in steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003e2-flute, coarse pitch design promotes chip evacuation in tough and gummy materials\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank provides positive, slip-resistant seating in standard end mill holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction with 30-degree medium helix angle\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish — no coating thickness to affect dimensional tolerances on close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill holders.

Secure the Weldon flat shank in a compatible end mill holder and confirm the set screw seats fully against the flat before operation. Inspect the spindle taper and holder bore for debris or damage before seating the tool. Follow machine tool manufacturer torque specifications for the holder set screw and verify runout with a dial indicator before taking a first cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (0.7087 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 to -0.0010 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\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix\u003c\/strong\u003e: 30 degrees (Medium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003ePitch\u003c\/strong\u003e: Coarse\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: End Mill Holders\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3CR\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 38249\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51738282623282,"sku":"38249","price":88.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e343cf5b624428e82e0c7f32266ee357.jpg?v=1788797646","url":"https:\/\/voomisupply.com\/products\/sgs-38249-corner-radius-end-mill-3-8in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
