Built on the ZH1C series platform, it features a 1\/4 inch mill diameter, a 1\/2 inch length of cut, and a 0.0200 inch corner radius that reduces stress concentrations at the cutting edge. The 4-flute, single-end geometry uses a variable helix and variable index design — ranging from 38 to 41 degrees — to dampen vibration and improve surface finish. An AlTiN coating, marketed under the Ti-NAMITE-A designation, provides thermal resistance and hardness for extended tool life in difficult materials. Machinists and CNC programmers working with ferrous and exotic alloys will find this tool suited for both roughing and finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills equipped with standard end mill toolholders accepting a 1\/4 inch straight cylindrical shank. Primary target materials include steel, stainless steel, cast iron, superalloys, and titanium. It also carries a secondary rating for hard materials. The short flute length and 2.5 inch overall length make it appropriate for close-tolerance work where rigidity and runout control are critical. Right-hand cutting direction with right-hand flute spiral is standard for conventional spindle setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix (38 to 41 degrees) and variable index reduce harmonic vibration during cutting\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating (Ti-NAMITE-A) delivers elevated thermal and abrasion resistance for ferrous and exotic alloy machining\u003c\/li\u003e\n  \u003cli\u003e0.0200 inch corner radius extends edge life and reduces chipping versus a sharp-corner end mill\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides stiffness and wear resistance across roughing and finishing operations\u003c\/li\u003e\n  \u003cli\u003eSingle-end, 4-flute geometry balances chip evacuation with cutting edge strength\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank with h6 tolerance ensures consistent clamping in collet chucks and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill toolholders accepting a 1\/4 inch straight cylindrical shank.

Confirm the spindle is fully stopped and the machine is in an appropriate safe state before tool changes. Seat the shank fully into the toolholder and torque the collet nut or set screw to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning cuts, as excessive runout will accelerate edge wear on carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5000 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: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 to 41 degrees (variable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand Spiral\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0012 \/ 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00000 to -0.00200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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, 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\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\u003eSeries\u003c\/strong\u003e: ZH1C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 36570\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51732331921714,"sku":"36570","price":60.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08ed5165d1994f40357a519026cdeb87.jpg?v=1788741709","url":"https:\/\/voomisupply.com\/products\/sgs-36570-corner-radius-end-mill-1-4-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
