Constructed from solid carbide and finished with an amorphous diamond coating, this end mill delivers extended tool life and reduced heat buildup in abrasive workpiece materials. It features 12 flutes arranged in a diamond pattern, which minimizes surface delamination and fraying common when machining fiber-reinforced composites. The 0.5-inch cutter diameter and 1.5-inch length of cut make it well-suited for profiling, slotting, and edge finishing operations. It accepts a standard 1\/2-inch shank and reaches a 3-inch overall length, fitting most standard router and CNC spindle setups. Installation and setup require no special modifications beyond correct collet sizing.\u003c\/p\u003e\n\u003cp\u003eThis router bit is designed primarily for machining composite materials, including fiber-reinforced plastics and similar abrasive laminates. It is typically used in CNC routing operations across aerospace fabrication, marine, and industrial manufacturing environments. The 12-flute diamond pattern geometry helps manage chip load per flute, producing cleaner cut edges on materials that would otherwise fray or delaminate with conventional end mills. It is installed and operated by machinists, CNC programmers, and tooling technicians working with composite substrates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAmorphous diamond coating for extended wear resistance in abrasive composite materials\u003c\/li\u003e\n  \u003cli\u003e12-flute diamond pattern geometry reduces delamination and surface fraying\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and heat resistance during high-speed cutting\u003c\/li\u003e\n  \u003cli\u003e0.5-inch cutter diameter with 1.5-inch length of cut for profiling and slotting applications\u003c\/li\u003e\n  \u003cli\u003eStandard 1\/2-inch shank diameter fits most CNC router collets and spindle toolholders\u003c\/li\u003e\n  \u003cli\u003eEnd mill geometry supports both peripheral and plunge-style cutting passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with composite material applications.

Always power down and lock out the spindle before changing tooling. Verify collet size matches the 1\/2-inch shank before tightening, and inspect the collet and toolholder for wear or runout prior to use. Do not exceed the tool manufacturer recommended feed and speed parameters for the specific composite substrate being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: End Mill\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Amorphous Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 921032-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51731067765042,"sku":"921032-C4","price":382.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/235fb5c9983a7507c1246f5e36aeaf12_9196e0a2-e53c-49a6-9f69-bdf7e67dac7d.jpg?v=1788726528","url":"https:\/\/voomisupply.com\/products\/harvey-tool-921032-c4-diamond-pattern-router-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
