Built from M42 cobalt high-speed steel, it handles interrupted cuts and harder workpiece materials that would wear down standard HSS tooling faster. The 9\/16 inch diameter cutting head features 4 flutes with a 30-degree helix angle and a square end profile, delivering efficient chip evacuation and a smooth finish on exit passes. The bright, uncoated surface finish is well-suited for general-purpose machining where coating is not required. This is a single-end tool with a Weldon flat shank for positive rotational drive in the spindle.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal milling applications across job shops, toolrooms, and production environments. The 1\/2 inch Weldon flat shank seats securely in side-lock holders, making it a reliable choice for face milling, slotting, and profiling operations on ferrous and non-ferrous materials. Right-hand cutting direction and right-hand flute direction are standard for conventional milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for improved hardness and heat resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003e4-flute, 30-degree helix square end geometry for roughing and finishing in one pass\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank for positive engagement in side-lock tool holders\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose milling applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for conventional spindle setups\u003c\/li\u003e\n\u003cli\u003eSingle-end design for straightforward indexing and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard side-lock Weldon flat end mill holders accepting a 1\/2 inch shank diameter.

Power down and lock out the spindle before changing tooling. Ensure the Weldon flat is properly aligned with the set screw in the holder to prevent slippage under cutting loads. Do not use this end mill in applications requiring center-cutting entry, as this tool is not centercutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/16 inches (0.5625 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: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/8 inches (1.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eWeight\u003c\/strong\u003e: 0.02 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: 724-4131\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692643287346,"sku":"724-4131","price":89.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebc25ebd90dba866a1c09e2182ac53ac.jpg?v=1788300475","url":"https:\/\/voomisupply.com\/products\/value-collection-724-4131-roughing-finishing-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
