It carries a 0.1875 inch cutter diameter with a 0.625 inch length of cut and a 0.25 inch shank diameter, making it suited to light-depth profiling and slotting passes where surface quality on the top face of the workpiece is a priority. The downcut flute geometry pushes chips downward, reducing workpiece lift and minimizing fraying on laminates, composites, and veneered materials. A 22-degree helix angle and right-hand cut direction are standard. The bright, uncoated finish is appropriate for non-ferrous metals, plastics, and composite materials. Overall length is 2 inches.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills where a small-diameter, single-flute tool is required for detailed profiling, climb milling in soft materials, or routing operations in wood composites, carbon fiber, and similar sheet goods. The 0.25 inch shank fits standard ER collets and end mill holders commonly found in production and prototype shops. It is installed and operated by machinists and CNC operators working in aerospace, woodworking, sign-making, and general fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDowncut flute geometry pushes chips toward the workpiece surface, reducing top-face tearout on laminates and composites\u003c\/li\u003e\n\u003cli\u003eSingle-flute design allows higher feed rates in soft or gummy materials and improves chip evacuation in deep slots\u003c\/li\u003e\n\u003cli\u003e22-degree helix angle balances cutting forces for stable passes at small diameters\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance compared to high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suits non-ferrous metals, plastics, and composite materials without risk of built-up edge from coating interaction\u003c\/li\u003e\n\u003cli\u003eRight-hand cut direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use single-flute downcut end mill for CNC machining centers and manual mills accepting a 0.25 inch shank diameter through standard ER collets or end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Power down and lock out the spindle before seating or removing the tool from the collet or holder. Ensure the shank is fully seated to the minimum insertion depth required by the holder manufacturer before torquing the collet nut. Verify runout with a dial indicator after tool change, as excessive runout at small diameters accelerates wear and increases the risk of tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Downcut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 22 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 44912\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51731976945970,"sku":"44912","price":78.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd98da7cd34b21d2b06517b142c63fc5.jpg?v=1788737513","url":"https:\/\/voomisupply.com\/products\/harvey-tool-44912-square-end-mill-3-16-in-1-flute-downcut-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
