The 3\/8-inch cutting diameter pairs with a 0.03-inch corner radius to blend strength with precision at the cutting edge. An AlTiN coating under SGS's Ti-NAMITE-A designation improves heat resistance and tool life in demanding cuts. With 4 flutes and a medium helix, the 38172 handles both roughing and finishing passes in a single setup. Licensed machinists and tool-and-die professionals use this end mill in CNC machining centers with standard end mill holders.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations in job shops, production facilities, and tool rooms working primarily with ferrous and superalloy materials. The 1-inch length of cut, 2.5-inch overall length, and 3\/8-inch Weldon flat shank make it a practical fit for medium-depth slotting, profiling, and contouring work where corner radius blending is required. The variable index geometry reduces harmonic chatter during heavier cuts. Hard materials are listed as a secondary workpiece material category, extending the range of the tool when cutting hardened steels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating (Ti-NAMITE-A) for elevated heat resistance and extended tool life in ferrous and superalloy materials\u003c\/li\u003e\n\u003cli\u003e0.03-inch corner radius reduces stress concentration at the cutting edge and improves surface finish at part corners\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing minimizes chatter and vibration during both roughing and finishing passes\u003c\/li\u003e\n\u003cli\u003eMicrograin carbide substrate provides wear resistance in abrasive and hard workpiece materials\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank ensures positive engagement in standard end mill holders\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cut with helical flutes for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill holders.

Suitable for primary workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, and superalloys and titanium; secondary application in hard materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Secure the Weldon flat shank fully into a clean, undamaged end mill holder and tighten set screws against the flat to prevent axial pullout. Verify spindle runout with a dial indicator before cutting to protect the corner radius geometry. Follow the machine shop's established speeds and feeds guidelines for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches\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: -0.002 to 0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.002 to -0.001 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: 1 inch\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: 0.375 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\u003eHelix Style\u003c\/strong\u003e: Medium\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (Ti-NAMITE-A)\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\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\u003eSeries\u003c\/strong\u003e: 01C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: SGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 38172\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51736840798514,"sku":"38172","price":98.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/504c0c69a72b716ed757d44258846af6.jpg?v=1788780948","url":"https:\/\/voomisupply.com\/products\/sgs-38172-corner-radius-end-mill-3-8-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
