With a cutting diameter of 0.0313 inches (1\/32 inch) and a 5\/64-inch length of cut, this tool is built for fine detail work in hard and abrasive materials. The AlTiN coating improves heat resistance and extends tool life in ferrous and high-temperature alloys. A 30-degree helix angle and spiral flute geometry promote efficient chip evacuation. Centercutting capability allows plunge entry directly into the workpiece. Machinists and tool-room operators working with CNC mills or manual machines in production or prototype environments rely on this type of end mill for micro-milling tasks.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for small-feature milling operations in aerospace, medical device, mold and die, and precision parts manufacturing. The 1\/8-inch shank diameter fits standard collets and end mill holders on CNC machining centers and manual knee mills. The regular-length geometry and 1-1\/2-inch overall length make it appropriate for shallow-to-moderate depth slots, pockets, and profile cuts where rigidity and minimal deflection are critical. Right-hand cut and right-hand flute orientation follow standard conventions for conventional and climb milling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0313-inch (1\/32 inch) cutting diameter for micro-milling and fine-detail work\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish for elevated heat resistance and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e4-flute, spiral flute design with 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute, standard orientation for most CNC setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/8-inch collets or end mill holders on CNC machining centers and manual milling machines.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the collet or holder. Verify runout with a dial indicator before committing to a production cut, as runout errors are amplified significantly at this diameter. Follow the machine and tooling manufacturer guidelines for speeds and feeds appropriate to the workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0313 inches (1\/32 inch)\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: 0.0781 inches (5\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5000 inches (1-1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51745386070322,"sku":"750420","price":27.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f36844804b220f5efe9baf657cdc5df0.jpg?v=1788863677","url":"https:\/\/voomisupply.com\/products\/hertel-750420-square-end-mill-1-32-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
