It features a 5\/16-inch cutter diameter, a 5\/8-inch length of cut, and a 2-1\/2-inch overall length. The tool carries an amorphous diamond coating, which significantly increases surface hardness and reduces friction, making it well suited for cutting abrasive non-metallic materials such as graphite, carbon fiber, fiberglass, and composites. The 0-degree helix and non-centercutting geometry reflect a design optimized for side milling and slotting in these demanding materials.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in production and job-shop machining environments where abrasive composite or non-ferrous materials are regularly encountered. The 5\/16-inch shank diameter allows direct collet chuck mounting in standard toolholding systems. Right-hand cutting direction makes it compatible with conventional CNC vertical and horizontal machining centers. It is a single-end tool sold individually and is most commonly installed by machinists and CNC programmers working with advanced materials that accelerate tool wear on uncoated carbide.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAmorphous diamond coating extends tool life in abrasive composite, graphite, and fiberglass applications\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate provides rigidity and resistance to deflection at small diameters\u003c\/li\u003e\n\u003cli\u003e2-flute geometry promotes chip evacuation during slotting and profiling\u003c\/li\u003e\n\u003cli\u003e0-degree helix angle reduces axial cutting forces, beneficial in thin or brittle workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eNon-centercutting design — suited for side milling and peripheral cuts, not plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard collet-style toolholding systems accepting a 5\/16-inch shank diameter.

The machine spindle must be fully stopped and power locked out before changing tooling. Seat the shank fully into a clean, matched collet or toolholder and torque the retention system per the toolholder manufacturer specification. This tool is non-centercutting — do not program direct plunge moves; use ramping or helical entry strategies where a full-depth entry is required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Single End, Non-Centercutting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit 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\u003ePackage Dimensions\u003c\/strong\u003e: 2.6 inches L x 0.51 inches W x 0.51 inches H\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: 14620-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51727368880434,"sku":"14620-C4","price":160.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/341d1b4b7ccbfed055cd640b4e1f7db5.jpg?v=1788676855","url":"https:\/\/voomisupply.com\/products\/harvey-tool-14620-c4-square-end-mill-5-16-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
