Built from solid carbide with a diamond finish coating, this bit delivers extended tool life and clean edge quality in demanding routing applications. The compression-style geometry combines upcut and downcut flute action to shear material from both faces simultaneously, reducing delamination and fraying on composite panel surfaces. At 0.25 inches in cutting diameter with a 45-degree helix angle and right-hand cutting direction, this bit is suited for CNC routing operations where surface finish and dimensional accuracy are priorities. Licensed trades and skilled machinists handling composite fabrication rely on this tool type for consistent, repeatable results.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for routing composite materials including laminates and engineered panels. The 0.75-inch length of cut suits through-cuts and profiling passes on typical composite sheet stock. The 0.25-inch shank diameter fits standard collets on CNC routers and conventional handheld router platforms. It is most commonly found in cabinetry shops, sign fabrication environments, and industrial composite panel operations where surface integrity on both the top and bottom face of the workpiece is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompression spiral geometry minimizes delamination on composite top and bottom faces\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eDiamond finish coating reduces friction and heat buildup during cutting\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle optimized for smooth chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard CNC and handheld router spindles\u003c\/li\u003e\n  \u003cli\u003e0.75-inch length of cut suited for full-depth passes on composite sheet panels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in composite material applications.

Ensure the router or spindle is fully powered down and isolated before inserting or removing the bit. Seat the shank fully into the collet to the recommended insertion depth and torque the collet nut according to the router manufacturer specifications. Inspect the bit for chips or coating damage before each use and do not operate at speeds exceeding the router or bit manufacturer rating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRouter Style\u003c\/strong\u003e: Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.2 inches L x 0.55 inches W x 0.45 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.065 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112821\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20642516\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752548729138,"sku":"20642516","price":283.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2b9a97c586d152f052849ee9155f704.jpg?v=1788929042","url":"https:\/\/voomisupply.com\/products\/osg-20642516-compression-spiral-router-bit-0-25-in","provider":"Voomi Supply","version":"1.0","type":"link"}
