It features a CVD diamond coating, making it well suited for machining highly abrasive non-ferrous materials such as graphite, carbon fiber, reinforced composites, and ceramics. The cutter measures 1\/8 inch (0.125 inch) in diameter with a 3\/16 inch (0.187 inch) length of cut and a 30-degree helix angle. At 2.5 inches overall length with a 1-inch extended reach, this end mill is built for shops and toolrooms requiring consistent, tight-tolerance results in difficult materials.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers handling composite layups, printed circuit board substrates, graphite electrodes, and other high-abrasion workpieces where diamond tooling extends tool life significantly over conventional coated carbide. The 4-flute, right-hand cutting and right-hand flute configuration supports conventional and climb milling strategies. Centercutting geometry allows plunge entry when the operation requires it. The extended reach design provides clearance in deeper pocket and slot applications where standard-length tools would not reach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD diamond coating for extreme wear resistance in abrasive non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand cut and right-hand helix for rigidity and chip control\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting forces and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eExtended reach at 1 inch provides clearance for deeper features\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction maintains dimensional stability under heat and load\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for CNC machining center spindles accepting a 1\/8 inch shank diameter collet or toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists or CNC tooling technicians. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Seat the 1\/8 inch shank fully into a matched collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before production runs, as excessive runout will shorten tool life significantly on diamond-coated tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/16 inch (0.187 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\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eCoating\u003c\/strong\u003e: CVD Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 960308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51729377460530,"sku":"960308","price":229.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05bab70f38396d5e8395b8985f50adaa.jpg?v=1788703836","url":"https:\/\/voomisupply.com\/products\/harvey-tool-960308-square-end-mill-1-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
