With 4 helical flutes and a centercutting geometry, this end mill supports both plunge cuts and lateral passes without requiring a pre-drilled entry point. The 3mm mill diameter and 6mm length of cut make it well suited for fine-detail slotting, profiling, and contouring work. A helix angle in the 29 to 31 degree range promotes efficient chip evacuation and reduces chatter at moderate to high spindle speeds. Machinists and tool-and-die technicians working on CNC machining centers and manual mills will find this a reliable small-diameter cutter for tight-tolerance work.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard 3mm cylindrical shank tool holders and collets. It is intended for use in CNC milling centers, vertical mills, and similar machine tool setups performing finishing and semi-finishing passes on ferrous and non-ferrous workpieces. The 38mm overall length provides adequate reach for most shallow to mid-depth cavity work without excessive deflection risk at this diameter. It is sold individually and is a direct replacement-style cutter for worn or broken small-diameter end mills in production and job shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e4 helical flutes for improved chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eHelix angle of 29 to 31 degrees balances cutting efficiency and edge strength\u003c\/li\u003e\n\u003cli\u003eCylindrical shank fits standard 3mm collets and tool holders\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker geometry — suited for finishing and light roughing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement small-diameter square end mill for use in standard 3mm collet and tool holder systems on CNC machining centers and manual vertical mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed and changed by machinists or CNC setup technicians. Always power down and lock out the spindle before changing tooling. Use the correct collet size and torque the tool holder to the machine manufacturer's specification using appropriate spanner wrenches. Inspect the shank for runout before beginning a cut, as deflection and tool breakage risk increase significantly at small diameters if the tool is not properly seated.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3mm (0.12 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\u003eLength of Cut\u003c\/strong\u003e: 6mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3mm (0.12 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38mm (1.5 inches)\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\u003eHelix Angle\u003c\/strong\u003e: 29 to 31 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14788508\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748148445490,"sku":"14788508","price":28.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b787590137219b26255542fa8e005c9c.jpg?v=1788889657","url":"https:\/\/voomisupply.com\/products\/accupro-14788508-square-end-mill-4-flute-solid-carbide-3mm","provider":"Voomi Supply","version":"1.0","type":"link"}
