Built from solid carbide with a bright uncoated finish, it delivers the hardness and edge retention needed when working through fiber-reinforced plastics, laminates, and similar composite substrates. The 118-degree drill point angle features an 8-facet grind and web thinning for cleaner entry and reduced thrust. At 3.25 inches overall length with a 2-inch flute, it fits standard drill chucks and CNC toolholders alike. This bit is part of the ONSRUD Series 67-800, a line aimed at general-purpose composite drilling applications.\u003c\/p\u003e\n\u003cp\u003eThe 67-815 is suited for drilling composite panels, stacked composite assemblies, and similar non-metallic materials in production or field settings. With a 1\/4-inch straight cylindrical shank and a 2-inch maximum drilling depth, it fits directly into standard drill chucks or collet-style toolholders without adapters. The 8xD flute-to-diameter ratio provides adequate chip evacuation in through-hole applications. This bit is typically deployed by fabricators, aerospace technicians, and composite repair specialists working on structural panels or layups where clean hole geometry matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for hardness and edge retention in abrasive composite materials\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point with 8-facet grind and web-thinned tip for reduced thrust and cleaner entry\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for composite substrates where coatings may cause delamination\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral with 2 flutes for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard chucks and collet toolholders without modification\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement  -  dry or mist cutting compatible with most composite work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for drilling composite workpiece materials, part of the ONSRUD Series 67-800.

Verify the tool is fully seated and the chuck is tightened before operation. When drilling composites, use appropriate feed and speed settings to prevent delamination or heat buildup at the drill point. Wear appropriate PPE including eye protection and a dust mask rated for composite particulate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: 8 Facet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 67-800\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 67-815\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67907279159602,"sku":"67-815","price":111.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c85c5c11c3d8747e26df891e6e6e116.jpg?v=1791176350","url":"https:\/\/voomisupply.com\/products\/onsrud-67-815-solid-carbide-jobber-drill-bit-1-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
