With a 1\/8 inch cutting diameter and a 3\/8 inch length of cut, this single-end tool delivers tight tolerances in small-feature work. The amorphous diamond coating provides enhanced surface hardness and lubricity, extending tool life when cutting abrasive non-ferrous materials, composites, and graphite. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. With four flutes and a right-hand cutting direction, this end mill is suited for finishing passes and fine detail work in CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is used in precision CNC milling applications where small-diameter tooling is required. Typical applications include machining of carbon fiber reinforced polymers, fiberglass, graphite electrodes, ceramics, and other abrasive non-metallic materials. The amorphous diamond coating makes it particularly effective in applications where uncoated or AlTiN-coated carbide would wear prematurely. It is used by machinist professionals and tool-and-die shops operating vertical or horizontal CNC machining centers requiring 1\/8 inch shank tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAmorphous diamond coating for extended tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate for rigidity and dimensional accuracy\u003c\/li\u003e\n\u003cli\u003e4-flute design with 30-degree right-hand spiral helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable for plunge entry\u003c\/li\u003e\n\u003cli\u003e1\/8 inch shank diameter matches cutting diameter for direct collet clamping\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 1-1\/2 inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and milling machines accepting 1\/8 inch shank tooling with standard ER or precision collet systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the spindle fully stopped and machine power locked out per shop safety procedures. Use a precision collet or toolholder rated for the 1\/8 inch shank diameter to ensure minimal runout. Confirm correct tool reach and clearance before beginning a cut cycle. Inspect the cutting edges and coating condition before each use, as chipped or worn flutes on small-diameter carbide tooling can cause workpiece damage or tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003c\/strong\u003e: Amorphous Diamond\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\u003eConfiguration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 73125-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51727634792754,"sku":"73125-C4","price":57.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9184774782667b791afe87d92ba49005_63d74a3d-1a13-4ac4-b82a-990a2d21face.jpg?v=1788680346","url":"https:\/\/voomisupply.com\/products\/harvey-tool-73125-c4-square-end-mill-1-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
