With a 3\/16 inch cutting diameter and four helical flutes, this end mill delivers clean, accurate cuts in ferrous and non-ferrous materials. The bright, uncoated finish is suited for applications where coating is not required or where the workpiece material is sensitive to coated tooling. At 2 inches overall length with a 5\/8 inch length of cut, this tool fits standard toolholders used in CNC and manual milling setups. It is a single-end tool in HTC Series 120.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in milling operations requiring a compact, short-reach cutting tool. The 3\/16 inch shank diameter matches the cutting diameter, allowing direct mounting in collet chucks and other standard toolholding systems without reduction. Right-hand cutting and right-hand flute direction make it compatible with conventional spindle configurations. Typical applications include slotting, profiling, and peripheral milling on steel, aluminum, brass, and similar materials. The standard length designation suits production and prototype work where rigidity and tool life are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior hardness and wear resistance compared to HSS tooling\u003c\/li\u003e\n\u003cli\u003eFour helical flutes for efficient chip evacuation and improved surface finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting and right-hand flute direction for use with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for a wide range of base materials\u003c\/li\u003e\n\u003cli\u003eNon-centercutting design  -  not intended for plunge cutting\u003c\/li\u003e\n\u003cli\u003eStandard length profile maximizes rigidity and minimizes deflection in tight setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 3\/16 inch collet chucks, end mill holders, and compatible toolholding systems on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the toolholder to the recommended engagement depth before tightening. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. This end mill is non-centercutting and must not be used for direct plunge operations  -  ramp or helical entry is required when cutting closed pockets.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\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: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: HTC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 120-4187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HTC","offers":[{"title":"Default Title","offer_id":68340353597746,"sku":"120-4187","price":40.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d56c0380c280b6ad566bca1995a2ae4.jpg?v=1793866389","url":"https:\/\/voomisupply.com\/products\/htc-120-4187-square-end-mill-3-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
