It features a 31\/64 inch diameter, a 118-degree standard point angle, and an uncoated HSS construction that delivers reliable performance across a wide range of ferrous and non-ferrous materials. With a 12-inch overall length and a 9-inch spiral flute, this bit clears chips effectively during extended drilling operations. It is a right-hand cutting, two-flute design with a straight-cylindrical shank sized at 31\/64 inch for secure chuck engagement. Machinists, pipefitters, ironworkers, and maintenance trades use this type of bit when penetrating thick stock, structural steel, or deep assemblies.\u003c\/p\u003e\u003cp\u003eThis extra length drill bit is suited for industrial and trade applications where through-hole drilling in thick materials, deep structural members, or stacked workpieces is required. The Series 686 designation places it in a family of extended-reach HSS bits appropriate for stationary drill press use, magnetic drill setups, and heavy-duty hand drilling. The uncoated finish makes resharpening straightforward, and the spiral flute geometry helps maintain consistent chip evacuation in both metal and wood substrates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e31\/64 inch diameter with matching 31\/64 inch straight-cylindrical shank for balanced chuck grip\u003c\/li\u003e\n\u003cli\u003e12-inch overall length provides extended reach for deep-hole and through-hole work\u003c\/li\u003e\n\u003cli\u003e9-inch spiral flute length promotes efficient chip evacuation in long-run drilling\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle suits general-purpose drilling in steel, iron, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction withstands elevated cutting temperatures without rapid edge degradation\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, two-flute design compatible with standard drill presses and hand drills\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-use extra length drill bit for any chuck accepting a 31\/64 inch straight-cylindrical shank, including standard keyed and keyless drill press chucks and magnetic drill adapters.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this bit is performed by machinists, pipefitters, ironworkers, or general maintenance technicians. Secure the straight shank fully into the chuck before operation and verify chuck key is removed before starting the machine. Use appropriate cutting fluid or coolant when drilling hardened or thick steel to extend edge life, and reduce feed pressure near breakthrough to prevent grab or workpiece movement. Wear appropriate eye and hand protection per shop safety standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 31\/64 inch (0.4844 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 31\/64 inch (0.4844 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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: 686\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.46 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: TITAN USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CD68631\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51755439292722,"sku":"CD68631","price":83.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c98d93a617ea4c6a4585028a83e55ec_57ab63b7-4ea0-4717-9244-9fce583eb24d.jpg?v=1788955098","url":"https:\/\/voomisupply.com\/products\/titan-usa-cd68631-extra-length-drill-bit-31-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
