Built from micrograin carbide, this single-end tool delivers sharp cutting edges and consistent performance in high-demand shop environments. It features a 10 mm shank diameter, a 25 mm overall length, and a 4-flute geometry that supports efficient chip evacuation and smooth surface finishes. The bright, uncoated finish makes it well suited for general-purpose cutting where coating is not required. This end mill is installed and operated by machinists and CNC operators working in production and job-shop settings.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills where a compact, short-reach tool is appropriate. The 25 mm overall length suits tight-clearance setups and applications requiring close spindle-to-workpiece proximity. Right-hand cutting direction and right-hand flute direction follow standard tooling conventions. The centercutting capability allows plunge milling in addition to peripheral and slot milling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003e4-flute design supports higher feed rates and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables plunge, slot, and peripheral milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand helix for standard CNC and manual mill compatibility\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for general-purpose machining\u003c\/li\u003e\n  \u003cli\u003eCompact 25 mm overall length for close-clearance setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-fitment square end mill for CNC machining centers and manual mills accepting a 10 mm round shank.

Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before inserting or removing the tool from the holder. Use an appropriate collet or end mill holder rated for the 10 mm shank diameter and verify runout with a dial indicator before cutting. Follow the machine manufacturer and tooling manufacturer feed and speed guidelines for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Type\u003c\/strong\u003e: Square\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\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 25 mm (0.984 inches)\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\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 404-3937\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746400698674,"sku":"404-3937","price":55.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/176ef6d222499ecf730f2a400c41a2f6_0c3712f9-c0fc-4a56-9dbd-72125c7167eb.jpg?v=1788869586","url":"https:\/\/voomisupply.com\/products\/osg-404-3937-square-end-mill-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
