Built from high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during cutting. The 135-degree split point starts on contact without a center punch, and the parabolic flute profile clears chips efficiently at higher feed rates. At 4.25 inches overall length with a 9\/32-inch straight-cylindrical shank, it fits standard drill chucks used by machinists, pipefitters, and HVAC and plumbing techs drilling through structural steel, angle iron, and mechanical components.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production and maintenance drilling in steel alloy workpieces across residential and light commercial trade applications. Typical scenarios include drilling pilot holes in steel brackets, electrical enclosures, ductwork hangers, pipe hangers, and similar metal fabrication tasks. The parabolic flute geometry and web-thinned tip make it a reliable choice when drilling through harder grades of carbon and alloy steel where standard jobber bits tend to walk or deflect. The Series 150DHT designation identifies it within the CHICAGO-LATROBE heavy-duty TiN-coated line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiN coating reduces friction and extends cutting life compared to uncoated HSS bits\u003c\/li\u003e\n  \u003cli\u003e135-degree split point starts on contact, eliminating the need for a center punch\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design improves chip evacuation at higher feed rates\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction reduces thrust and cutting resistance\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade rated for steel alloy as the primary workpiece material\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 a jobber length replacement or general-purpose drill bit for use in standard drill chucks accepting a 9\/32-inch straight-cylindrical shank.

Ensure the workpiece is clamped or secured before drilling to prevent rotation or shifting. Use appropriate cutting fluid or lubricant when drilling through steel alloy to extend bit life and maintain cutting edge integrity. Inspect the cutting edge before each use and replace the bit if chipping or dulling is observed.\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\/32 inch (0.2812 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 53911\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51730432786738,"sku":"53911","price":21.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/486223d907f5d2125b35c64cb3bab824.jpg?v=1788717378","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53911-jobber-drill-bit-9-32-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
