Built from high speed steel with a titanium nitride (TiN) coating, this 19\/32-inch diameter bit delivers extended tool life and reduced friction compared to uncoated HSS tooling. The 135-degree split point reduces walking on entry and allows drilling without a center punch on most surfaces. With an overall length of 8.75 inches and a 6.5-inch parabolic flute, the 55270 handles deeper holes while maintaining efficient chip evacuation. Machinists, tool-and-die technicians, and maintenance mechanics are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe 55270 is suited for drilling into alloy steel, carbon steel, aluminum, and other non-ferrous metals in production machining, maintenance repair, and fabrication settings. The tanged shank with a 0.5-inch shank diameter seats securely in standard Morse taper drill press spindles and similar machine tool holders. The right-hand cutting direction and parabolic flute geometry promote aggressive chip clearing in deeper holes, reducing heat buildup and bit deflection. This bit is part of the Chicago-Latrobe Series 120DHT lineup, which is built for heavy-duty drilling cycles where standard-length bits are insufficient for depth requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiN coating extends tool life and lowers cutting friction on ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point self-centers on entry, minimizing the need for a center punch\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile promotes fast, clean chip evacuation in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eTanged shank provides positive drive in Morse taper spindles, preventing slippage under load\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty Series 120DHT grade construction handles high-cycle and production drilling demands\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0012 inches ensures close-fit hole accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill press and machine tool spindles accepting a tanged shank with a 0.5-inch shank diameter.

Always secure the workpiece and confirm spindle speed is appropriate for the material and bit diameter before beginning a cut. Use cutting fluid when drilling steel to manage heat and prolong bit life. Inspect the cutting edges before each use and remove the bit from service if the TiN coating is worn through or the flutes show chipping.\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\/32 inch (0.5938 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 Length\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Tanged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\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\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel (HSS)\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: +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Non-Ferrous Metals\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: 120DHT\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: 55270\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51962041499954,"sku":"55270","price":105.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308b778c8c5cb245de4334c38cada87c_23ca4f11-9e5e-44d2-bb6d-33c4c9d48c10.jpg?v=1789947430","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-55270-taper-length-drill-bit-19-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
