It features a 3\/8-inch cutting diameter, three helical flutes, and a 45-degree helix angle that promotes efficient chip evacuation and smooth surface finishes in non-ferrous applications. The cutting edges carry a Zplus ZrN (zirconium nitride) coating, which reduces built-up edge and extends tool life when cutting aluminum alloys, brass, copper, and similar materials. This tool is intended for use by machinists and CNC operators running production or prototype work on vertical machining centers and mill-turn equipment.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling operations in aluminum and other non-ferrous workpiece materials. Its right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. The 3\/4-inch length of cut and 2.5-inch overall length make it appropriate for moderate-depth passes in typical fixturing setups. It is well matched to applications where chip packing and galling are concerns, particularly in high-speed aluminum roughing and finishing cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance compared to HSS tooling\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes aggressive chip lift and reduces cutting forces in aluminum\u003c\/li\u003e\n\u003cli\u003eZplus ZrN coating minimizes built-up edge and extends tool life on non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eThree-flute geometry balances chip clearance with surface finish quality\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry where required\u003c\/li\u003e\n\u003cli\u003eStraight 3\/8-inch shank fits standard ER and side-lock toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in aluminum and non-ferrous milling applications as part of the Helical Solutions End Mills for Aluminum 3 Flute Square 45 degree Helix series.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank to the full recommended engagement depth in the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning a cutting cycle, 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: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7500 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches (2-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Zplus ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.119 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: HELICAL SOLUTIONS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 81560\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51744833765682,"sku":"81560","price":80.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/abf5f097c803582698c3fff5a30bbe1f_22fcd9e6-6f87-4883-bc65-838a49adef56.jpg?v=1788861208","url":"https:\/\/voomisupply.com\/products\/helical-solutions-81560-3-8-in-3-flute-carbide-square-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
