Built from high speed steel (HSS) and coated with titanium nitride (TiN), it delivers improved surface hardness and extended tool life compared to uncoated HSS. The 135-degree split point reduces walking on contact and lowers the thrust required to start a hole. At 2-5\/8 inches overall length with a 7\/64-inch diameter, this bit fits standard drill chucks and is sized for precision work in tight or moderate clearance applications. It is suited for machinists, HVAC technicians, plumbers, and electricians who need reliable hole placement in metal components.\u003c\/p\u003e\n\u003cp\u003eThe 54086 is used in production drilling, maintenance, and field service applications where accurate, clean holes in steel alloy workpieces are required. The parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup and the risk of chip packing in deeper holes. It is a practical choice for drilling through sheet metal, bracket stock, pipe hangers, and structural components encountered in mechanical and electrical trades work. No coolant-through capability is present, so conventional cutting fluid or dry drilling practice applies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/64-inch (0.1094 inch) diameter with a tight diameter tolerance of -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and minimizes bit walking on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and reduces friction\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design promotes fast, efficient chip removal in steel alloy\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber drill bit replacement for use in standard drill chucks accepting a 7\/64-inch straight-cylindrical shank, with primary workpiece compatibility rated for steel alloy materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and operated by machinists, maintenance technicians, and trade professionals using handheld or bench-mounted drills. Secure the straight-cylindrical shank firmly in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Apply appropriate cutting fluid when drilling steel alloy to extend bit life and improve hole quality. Inspect the cutting edges for wear or chipping before each use and replace if the split point or flute geometry is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/64 inches (0.1094 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\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: 150DHT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 54086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51730747654450,"sku":"54086","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac936d5270b852c6540971f2b1ee1eab.jpg?v=1788722172","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-54086-7-64-in-jobber-drill-bit-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
