With a 0.25-inch cutting diameter, a 1.5-inch length of cut, and a 4-inch overall length, this tool delivers consistent material removal in a compact, rigid form factor. The 2-flute geometry promotes efficient chip evacuation, and the 30-degree spiral helix angle balances cutting pressure with surface finish quality. Machinists and CNC operators use this end mill for slotting, profiling, and peripheral milling in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills equipped with a 0.25-inch collet or ER-style toolholder. The centercutting design allows plunge entry directly into the workpiece, eliminating the need for a pre-drilled pilot hole in many applications. Right-hand cut and right-hand spiral flute direction are standard for conventional CNC spindle rotation. The single-end, uncoated solid carbide construction is appropriate for shops that rely on regrinding programs or prefer uncoated tools for specific material applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003e2-flute design promotes chip clearance in slotting and deep-pocket operations\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting forces and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with spiral flute for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for regrinding or material-specific applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any 0.25-inch collet, ER collet chuck, or end mill holder with a 0.25-inch bore.

Ensure the spindle is fully stopped and the machine is powered down or in E-stop before changing tooling. Seat the 0.25-inch shank fully into the collet or holder to the recommended engagement depth and torque the retention nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing a cut to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750081\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733718171954,"sku":"750081","price":51.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8579598f74b62b98f73529a454f915be.jpg?v=1788758786","url":"https:\/\/voomisupply.com\/products\/hertel-750081-square-end-mill-0-25in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
