It is designed for milling, slotting, and profiling operations on a wide range of metals and engineering materials. The cutter diameter is 20 mm (0.7874 inches), with a length of cut of 1.875 inches and an overall length of 4.125 inches. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation and smooth cutting action. The bright, uncoated finish is standard for general-purpose HSS tooling. This end mill is installed and operated by machinists and tool-and-die professionals on vertical mills, CNC machining centers, and manual knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for general-purpose milling in job shops, maintenance facilities, and production environments. The 20 mm cutter diameter and 1.875-inch length of cut make it appropriate for full-slot and peripheral milling passes at moderate depths. The 3\/4-inch shank diameter fits standard ER collet chucks, end mill holders, and Weldon-style holders common across vertical and horizontal milling setups. It is centercutting, allowing direct plunge entry into the workpiece without a pre-drilled pilot hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2 high speed steel construction for reliable performance across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e20 mm (0.7874 inch) cutter diameter with a 1.875-inch length of cut\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral design at 30-degree helix angle for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry permits direct plunge milling\u003c\/li\u003e\n\u003cli\u003e3\/4-inch shank diameter compatible with standard milling machine toolholders\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — suitable for use with cutting fluids on a wide range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or working-stock square end mill for standard milling machines and CNC machining centers accepting a 3\/4-inch shank.

Ensure the milling machine spindle is fully stopped and locked out before inserting or removing the end mill. Seat the shank to the full recommended insertion depth in the toolholder to prevent pullout under cutting load. Verify runout with a dial indicator after installation and before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 20 mm (0.7874 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: High Speed Steel, M2 grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.875 inches (1-7\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches (4-1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches (3\/4 inches)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eVariable Helix\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: VCCC-HSS-4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.047 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 720-8200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723651907890,"sku":"720-8200","price":80.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d65d90f46e75075b6808b3514a539a6.jpg?v=1788607222","url":"https:\/\/voomisupply.com\/products\/value-collection-720-8200-square-end-mill-20mm-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
