Built from 3% vanadium high speed steel, this tool delivers improved wear resistance over standard M2 HSS, making it suitable for tougher interrupted cuts and abrasive workpiece materials. The TiCN surface finish further extends tool life by reducing friction and heat buildup at the cutting edge. With a 0.7188-inch (23\/32 inch) cutting diameter, four spiral flutes at a 30-degree helix angle, and a 1.625-inch length of cut, this end mill is well suited for slot milling, peripheral milling, and side milling applications in a production or job-shop environment.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard CNC machining centers and manual knee mills using a 0.5-inch shank collet or end mill holder. The centercutting geometry allows direct plunge entry into the workpiece without pre-drilling. Right-hand cut with right-hand flute direction is the conventional configuration for most vertical milling setups. The 3.625-inch overall length keeps the tool compact and rigid, minimizing deflection during full-depth passes. Machinists and tool-and-die professionals will find this a practical general-purpose tool for daily production work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3% vanadium high speed steel construction for improved wear resistance over standard HSS grades\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes at 30-degree helix angle for smooth chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration for standard vertical mill setups\u003c\/li\u003e\n\u003cli\u003eRegular length profile (3.625 inches OAL) promotes rigidity and reduces deflection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any CNC or manual milling machine equipped with a 0.5-inch collet, end mill holder, or Weldon-style toolholder.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or end mill holder to the minimum insertion depth required by the holder manufacturer to prevent pullout under cutting loads. Verify runout with a dial indicator after clamping, as excessive runout accelerates flute wear and reduces surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 23\/32 inch (0.7188 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/8 inches (3.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Vanadium High Speed Steel (3% Vanadium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 3% Vanadium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface Finish\u003c\/strong\u003e: TiCN\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\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5742108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748848107826,"sku":"5742108","price":100.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0da405d3f84ea426c56954423254774.jpg?v=1788899493","url":"https:\/\/voomisupply.com\/products\/osg-5742108-square-end-mill-23-32-in-4-flute-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
