This single-end tool features a 3\/16 inch mill diameter, a 5\/8 inch length of cut, and a 2 inch overall length. The 4-flute geometry and 30-degree helix angle promote efficient chip evacuation and smooth cutting action. An amorphous diamond PVD coating extends tool life when cutting ferrous and non-ferrous materials. The centercutting design allows plunge entry, giving machinists flexibility in programming approach paths. Weighing 0.01 pounds, this miniature end mill is suited for tight-tolerance finish work in production and prototype environments.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for milling steel, stainless steel, cast iron, aluminum and non-ferrous alloys, and carbon fiber reinforced polymer (CFRP) materials. It fits standard CNC machining centers and manual knee mills with a 3\/16 inch collet or toolholder. The stub and standard length geometry keeps deflection low at small diameters, making it a practical choice for slots, pockets, and contours in miniature components. Right-hand cut and right-hand flute orientation are compatible with standard spindle rotation on most machine tools.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n\u003cli\u003eAmorphous diamond PVD coating rated for steel, stainless steel, cast iron, aluminum, and CFRP\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits plunge and ramp entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration in the miniature stub and standard series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fitment tool for CNC machining centers and manual mills equipped with a 3\/16 inch collet or toolholding system.

Ensure the spindle is fully stopped and the machine is powered down before loading or changing tooling. Seat the 3\/16 inch shank fully into a matched collet and torque the collet nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning 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: 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\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: Amorphous Diamond (PVD Diamond)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eVariable Index\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\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Square - Stub and Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73187-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51749407883570,"sku":"73187-C4","price":62.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7078afce062249e9400caa91850fe568.jpg?v=1788905698","url":"https:\/\/voomisupply.com\/products\/harvey-tool-73187-c4-square-end-mill-3-16-inch-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
