With a 0.0550-inch cutting diameter and a 0.275-inch length of cut, this end mill is built for small-diameter work where accuracy and tool rigidity are critical. The 0.125-inch shank diameter and 2.5-inch overall length allow it to seat securely in standard collet holders. Three flutes and a 30-degree helix angle promote efficient chip evacuation and a smooth cutting action. The bright, uncoated finish makes it well-suited for a range of workpiece materials. Machinists and CNC operators performing fine detail work or finishing passes in tight geometries are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for light to moderate material removal in precision machining environments including job shops, aerospace component work, and mold and die applications. The small 0.0550-inch diameter makes it particularly useful for slotting, profiling, and contouring in confined areas or small-feature geometries. Centercutting capability allows plunge entry directly into the workpiece. Right-hand cut and right-hand flute direction conform to standard CNC spindle rotation, requiring no special toolpath adjustments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0550-inch cutting diameter for small-feature and fine-detail milling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for a broad range of materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/8-inch collet holders and compatible tool holders accepting a 0.125-inch shank diameter.

Ensure the spindle is fully stopped and the machine is powered down or in a safe state before changing tooling. Seat the shank fully and evenly in the collet to the recommended engagement depth to minimize runout and prevent tool pullout during cutting. At small diameters, excessive feed rates or lateral forces can cause tool breakage  -  follow the manufacturer recommended speeds and feeds for the specific workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.0550 inches (1.4 mm)\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: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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\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\u003eEnd Mill Material\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: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31855\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51740400714034,"sku":"31855","price":53.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8842c115dffb99c3f73becd1f95e76e1_23dc55eb-22b5-41d6-a887-8e4105c88b44.jpg?v=1788824764","url":"https:\/\/voomisupply.com\/products\/harvey-tool-31855-square-end-mill-0-0550-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
