It features a 3\/16 inch (0.1875 inch) cutter diameter, a 5\/8 inch (0.6250 inch) length of cut, and a drill point end type that allows plunge entry into workpieces. The AlTiN (Aluminum Titanium Nitride) coating extends tool life by reducing heat buildup and wear during aggressive composite cutting cycles. The right-hand cutting direction suits standard CNC spindle rotation, and the 1\/4 inch shank fits common CNC collet systems without adapters.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for composite material applications including fiberglass, carbon fiber, G10, and similar laminates typically routed on CNC machining centers in aerospace, industrial, and fabrication environments. The diamond pattern geometry helps manage chip evacuation and reduces delamination at cut edges, which is a common concern when routing layered composite panels. The 1-3\/8 inch shank length provides adequate grip depth in standard ER or straight-bore collets, and the 2 inch overall length keeps the tool compact for rigid, chatter-free cuts in production setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and long tool life in abrasive composite materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating reduces friction and heat, extending usable tool life in high-speed CNC cycles\u003c\/li\u003e\n  \u003cli\u003eDrill point end type allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eDiamond pattern geometry promotes clean cuts and reduced delamination in composite laminates\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank fits common ER16 and ER20 collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on CNC machines with a 1\/4 inch collet; intended for routing composite materials as part of the ONSRUD 66-900 series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified CNC machinist or tooling technician. Power down and lock out the CNC spindle before changing tooling. Insert the shank fully into the collet to the recommended grip depth and torque the collet nut to the machine manufacturer's specification using the correct collet wrench. Verify runout with a dial indicator before beginning production cuts, as excessive runout accelerates wear on carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6250 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.375 inches (1-3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Drill Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Tool Type\u003c\/strong\u003e: CNC Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 66-900\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: ONSRUD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66-908ALTIN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67911856062770,"sku":"66-908ALTIN","price":163.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d156f2ae9a8d4d356acb2f712215cb5.jpg?v=1791221958","url":"https:\/\/voomisupply.com\/products\/onsrud-66-908altin-diamond-pattern-router-bit-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
