It features a 12 mm mill diameter, a 25 mm length of cut, and a 1.00 mm (0.0394 inches) corner radius that reduces stress concentration at the cutting edge and extends tool life in aggressive applications. The five-flute, right-hand helical design with a high helix angle supports both roughing and finishing operations in a single tool. An AlTiN coating, marketed under the Ti-NAMITE-A designation, provides excellent heat resistance and hardness retention at elevated cutting temperatures. This end mill is intended for use by machinists and CNC operators in precision machining environments.\u003c\/p\u003e\u003cp\u003eThe SGS 42681 is suited for milling steel, stainless steel, cast iron, superalloys, and hard materials in both roughing and finishing passes. With a straight-cylindrical shank and standard length profile, it seats directly in conventional end mill holders for CNC machining centers and manual mills. The variable index geometry helps break up harmonic vibration during aggressive cuts, making it a practical choice for high-material-removal-rate operations where surface finish still matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12 mm mill diameter with 12 mm straight-cylindrical shank, shank tolerance h6\u003c\/li\u003e\n\u003cli\u003e1.00 mm corner radius (0.0394 inches) reduces edge chipping and stress risers\u003c\/li\u003e\n\u003cli\u003eFive flutes with right-hand helical flute direction and high helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eAlTiN coating (Ti-NAMITE-A) for elevated heat resistance in ferrous and exotic alloy machining\u003c\/li\u003e\n\u003cli\u003eVariable index geometry reduces vibration and chatter during roughing passes\u003c\/li\u003e\n\u003cli\u003eCapable of both roughing and finishing cuts in steel, stainless steel, cast iron, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill holders.

Seat the shank fully in a clean, undamaged end mill holder and torque the retention mechanism to the holder manufacturer's specification. Inspect the corner radius and cutting edges for chipping before each use. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 12.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 25.00 mm (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.00 mm (0.0394 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\u003c\/strong\u003e: AlTiN (Ti-NAMITE-A)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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\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; 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0508 to 0.0000 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0500 to 0.0000 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 55C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: 42681\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51740319351090,"sku":"42681","price":204.65,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75fe9bc67f3be0a902a338902241b92c.jpg?v=1788824266","url":"https:\/\/voomisupply.com\/products\/sgs-42681-corner-radius-end-mill-12mm-5-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
