Built from micrograin solid carbide, it delivers the rigidity and wear resistance required for demanding cuts in ferrous and non-ferrous materials. The 0.25-inch diameter and 0.75-inch length of cut make it well suited for profiling, slotting, and finishing passes where accuracy and edge retention are critical. A TiCN coating reduces friction and extends tool life compared to uncoated carbide. The right-hand cut and right-hand spiral flute geometry, combined with a 30-degree helix angle and variable index design, promote smooth chip evacuation and reduce chatter during the cut.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for use in CNC machining centers and manual knee mills across residential shop, job shop, and production environments. The centercutting geometry allows direct plunge entry into the workpiece without a pre-drilled pilot hole. Compatible workpiece material codes include H, K, M, N, P, and S, covering hardened materials, cast iron, stainless steel, non-ferrous alloys, steel, and high-temperature alloys. The straight cylindrical shank fits standard ER and set-screw style collet chucks sized for 0.25-inch tooling. This is a regular-length, single-end tool intended for general-purpose milling tasks where tight dimensional tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and improves wear resistance over uncoated tooling\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand spiral configuration promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle reduces cutting forces and minimizes vibration\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing helps suppress chatter in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuitable for machining workpiece materials corresponding to codes H, K, M, N, P, and S, which include hardened steels, cast iron, stainless steel, non-ferrous metals, carbon and alloy steels, and high-temperature superalloys.

Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before inserting or removing the end mill. Seat the shank fully into the collet or tool holder to the recommended gauge line depth before torquing the retention nut. Verify runout with a dial indicator after clamping, as excessive runout accelerates edge wear and reduces dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 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: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00035 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: 39031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51728464740658,"sku":"39031","price":45.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1de11e04264b6aa311469bbac30fb496_c1fdc828-a78d-49fe-875b-25be74c46433.jpg?v=1788691618","url":"https:\/\/voomisupply.com\/products\/sgs-39031-square-end-mill-0-25-in-4-flute-solid-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
