With a 0.25 inch cutter diameter and a 1.25 inch length of cut, it delivers clean, accurate profiles in a compact geometry. The right-hand upcut flute with a 22-degree helix angle efficiently evacuates chips while pulling them upward away from the workpiece. At 3 inches overall length and a 0.25 inch shank diameter, it fits standard collets and tool holders found on most CNC machining centers and manual mills. Centercutting geometry allows plunge entry, adding versatility to slotting and profiling applications. Weighing 0.06 pounds, it is a lightweight tool suited for fine detail work and tight-tolerance jobs.\u003c\/p\u003e\u003cp\u003eThis end mill is well-suited for applications requiring high chip clearance in single-pass cuts, particularly in soft metals, plastics, and composites where the single-flute geometry prevents chip re-cutting and reduces heat buildup. The bright uncoated finish makes it a practical choice for materials where coated tools may cause adhesion issues or where re-sharpening is anticipated. Machinists and CNC operators working on prototyping, pattern work, or production runs with non-ferrous materials will find this geometry efficient and predictable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-flute upcut design promotes aggressive chip evacuation and reduces recutting\u003c\/li\u003e\n\u003cli\u003e22-degree helix angle balances cutting forces and surface finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance compared to HSS tooling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for non-ferrous metals, plastics, and composites\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide end mill for use in standard 1\/4 inch collets, ER collet chucks, and tool holders on CNC machining centers, routers, and manual milling machines requiring a single-flute square end mill.\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 inserting or removing the tool from its holder. Ensure the shank is fully seated to the recommended insertion depth in the collet or tool holder and torqued to the tool holder specification before operation. Inspect the cutting edges for chips or damage before each use, as solid carbide tools can fracture under interrupted cuts or improper runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches (1-1\/4 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: 3 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: Upcut\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\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 52516\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51785755918642,"sku":"52516","price":85.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d199482b9b47746c1eb0fe2a32d2eed6_5aceca5a-3718-42fa-94a8-7ef29ec888cb.jpg?v=1789201212","url":"https:\/\/voomisupply.com\/products\/harvey-tool-52516-square-end-mill-1-4-in-1-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
