Built from high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life in demanding conditions. The 135-degree split point reduces walking on entry and lowers thrust requirements compared to conventional 118-degree points. At 2-7\/8 inches overall length with a 1-3\/4 inch flute length and a 9\/64 inch (0.1406 inch) diameter, this bit fits standard drill chucks and fits within the Series 150DHT design specification. It is suited for production drilling, maintenance work, and fabrication shops where consistent hole quality in steel alloy is required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for drilling steel alloy and similar ferrous materials in residential, commercial, and light industrial settings. The parabolic flute geometry improves chip evacuation during deeper cuts, reducing heat buildup and the risk of bit binding. Right-hand cut orientation is standard for conventional drill press and hand drill operation. Licensed tradespeople in HVAC, plumbing, and electrical work routinely use bits of this type when drilling through structural steel, sheet metal brackets, and equipment panels. The straight-cylindrical shank seats cleanly in both keyed and keyless chucks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and lowers entry thrust on hard steel\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and extends service life\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design promotes rapid chip clearance in deeper holes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade high speed steel construction for demanding production use\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber-length drill bit for use in any standard drill press, hand drill, or drill driver accepting a 9\/64 inch straight-cylindrical shank.

Secure the workpiece firmly before drilling and wear appropriate eye protection. Ensure the drill chuck is fully tightened on the shank before operation. Do not force the bit at excessive feed rates, as this can cause premature coating wear or tip breakage, particularly in hard alloy steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9\/64 inches (0.1406 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9\/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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel Alloy\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 53902\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51732720222514,"sku":"53902","price":76.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00689e15ec4e2dce4c7d6c632eb68a81.jpg?v=1788746012","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53902-9-64-inch-hss-tin-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
