Built from micrograin carbide, it delivers consistent edge integrity and dimensional accuracy across a wide range of workpiece materials. The 4-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The variable index design reduces harmonic vibration during cuts, contributing to better surface finish. At 0.375 inches in diameter with a 0.625-inch length of cut and a 2.0-inch overall length, this stub-length tool is suited for rigid setups where reach is not the primary concern. It is installed and used by machinists and tool-and-die professionals in CNC and manual milling applications.\u003c\/p\u003e\u003cp\u003eThe SGS 31617 is intended for use in stub-length milling applications where rigidity and accuracy are priorities. Its centercutting geometry allows plunge entry, adding flexibility to slotting and pocket milling operations. The primary workpiece material codes cover a broad spectrum: H, K, M, N, P, and S material groups, which correspond to hardened steels, cast irons, stainless steels, non-ferrous materials, carbon and alloy steels, and heat-resistant superalloys. It is well suited for general-purpose machining in job shop, production, and maintenance environments running ferrous and non-ferrous stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for extended tool life and edge retention\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces vibration and improves surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard CNC and manual mill spindles\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for secure clamping in collet or end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for stub-length square end mill applications across CNC machining centers and manual knee mills accepting a 3\/8-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using a collet chuck, end mill holder, or Weldon-style holder matched to the 3\/8-inch shank diameter. Ensure the spindle and machine are fully powered down and locked out before changing tooling. Verify shank seating depth and runout with a dial indicator before commencing cuts. Follow shop-standard torque procedures for the holder type in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\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\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eChipbreaker\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 31617\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51738505183538,"sku":"31617","price":70.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc3f10d1059819ab1652e1ff9f384b90.jpg?v=1788800369","url":"https:\/\/voomisupply.com\/products\/sgs-31617-square-end-mill-3-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
