Built from solid carbide with a TiAlN coating, it handles high-heat cutting conditions that standard HSS tooling cannot sustain. The 1\/2 inch diameter, four-flute design with a fine pitch and right-hand spiral flutes produces a controlled chip load across a 5\/8 inch length of cut. The Weldon flat shank provides a positive drive connection in set-screw tool holders, reducing pull-out risk under heavy feeds. Machinists and tool-and-die professionals use this end mill for roughing passes on ferrous and non-ferrous workpieces in CNC milling and manual vertical mill applications.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing operations in job shop, production machining, and maintenance-repair environments. The 45-degree chamfer geometry and 20-degree maximum helix angle make it appropriate for side milling, slotting, and pocket roughing where chip evacuation and tool life under continuous cuts are priorities. The center-cutting design allows plunge entry. At 2-1\/2 inches overall length, it fits standard short-reach tool holders used on vertical machining centers and knee mills without extended-reach adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN coating for extended tool life in high-heat cuts\u003c\/li\u003e\n\u003cli\u003eFour-flute fine pitch configuration for aggressive roughing with controlled chip load\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — supports direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank eliminates pull-out in set-screw tool holders under heavy feed rates\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute spiral for standard CNC and manual mill spindles\u003c\/li\u003e\n\u003cli\u003e45-degree chamfer angle at 0.025 inch chamfer width for edge stability at cut entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 1\/2 inch bore Weldon flat tool holders on CNC vertical machining centers and manual knee mills.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the Weldon flat fully against the set screw contact point in the holder before torquing to the holder manufacturer specification. Verify runout with a dial indicator after tool changes on precision work to confirm proper seating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\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\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.0250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Helix Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.060 to -0.060 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SR420\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17004670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559791952178,"sku":"17004670","price":179.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee03d1060b4780fbf6429e3b9898ae70.jpg?v=1786441193","url":"https:\/\/voomisupply.com\/products\/seco-17004670-roughing-end-mill-1-2-inch-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
