It is manufactured from high speed steel and finished with a titanium nitride (TiN) coating that reduces friction and extends cutting life. The 135-degree split point geometry starts on contact without a center punch, reducing walking on hard surfaces. With a parabolic flute design, the bit evacuates chips efficiently during deep drilling. Overall length is 4-3\/8 inches, with a flute length of 3-1\/16 inches. The straight-cylindrical shank measures 19\/64 inches in diameter, matching the cutting diameter for direct chuck mounting.\u003c\/p\u003e\n\u003cp\u003eThe 53912 is suited for production drilling and field work in metal fabrication, mechanical contracting, HVAC installation, and plumbing rough-in where steel alloy materials are regularly encountered. The parabolic flute geometry makes it particularly effective in applications requiring clean, fast chip removal in deeper holes. It is sold individually and is appropriate for use in handheld drills, drill presses, and magnetic base drills accepting a straight-cylindrical shank. Its heavy-duty grade rating makes it a better choice for repeated use in professional shop or jobsite environments than general-purpose utility bits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point starts on contact, no center punch required\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile improves chip evacuation in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating reduces friction and increases wear resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration for reduced thrust and smoother entry\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade high speed steel construction rated for steel alloy workpieces\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series 150DHT OEM-style replacement or direct-use jobber drill bit for applications involving steel alloy primary workpiece material, compatible with any drill accepting a 19\/64-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the chuck before operation and confirm the chuck key is removed before starting the drill. Use appropriate cutting fluid or coolant on steel alloy workpieces to preserve coating life and maintain dimensional accuracy. Right-hand cut only — do not run in reverse rotation. Inspect the cutting edges and TiN coating before each use; a chipped or worn tip should be replaced rather than field-sharpened without proper HSS grinding equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 19\/64 inches (0.2969 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\u003eOverall Length\u003c\/strong\u003e: 4-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 19\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches (33.34 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eDrill Bit Grade\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: 53912\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51737510871346,"sku":"53912","price":23.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/292ea56b2d4c62e57226be5424f9828e.jpg?v=1788789496","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53912-jobber-drill-bit-19-64-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
