The bit is manufactured from high speed steel and coated with titanium nitride (TiN) to extend cutting life and reduce heat buildup at the tip. The 135-degree split point initiates cuts quickly without a center punch and minimizes walking on hard surfaces. A parabolic flute geometry moves chips out of the hole efficiently, reducing recutting and heat accumulation during deeper passes. At 4.125 inches overall length with a 2.875-inch flute, this is a standard jobber proportion suited for benchtop drill presses, CNC drilling centers, and hand-held power drills.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for drilling steel alloy workpieces in light manufacturing, fabrication, mechanical maintenance, and trade service applications. The straight-cylindrical shank at 0.2570 inches diameter seats securely in standard keyless or keyed three-jaw chucks without adapters. The Series 150DHT designation places this bit in CHICAGO-LATROBE's heavy-duty TiN-coated line, which is engineered for production and repetitive-use environments where bit longevity under load matters more than initial cost.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter F size — 0.2570 inches diameter with a tolerance of -0.0010 to 0.0000 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces thrust force and eliminates pilot-hole requirements on most steel surfaces\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and extends tool life compared to uncoated HSS bits\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile promotes fast chip evacuation in deep-hole drilling applications\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with web thinning maintains strength while lowering cutting resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank — compatible with standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct service bit for use in standard three-jaw drill chucks accepting a 0.2570-inch straight-cylindrical shank.

Secure the shank fully in the chuck and verify runout is within acceptable limits before beginning a cut. TiN-coated bits should not be reground without removing the coating in the regrind zone, as uneven coating can affect balance and cut quality. Follow applicable OSHA and shop-safety guidelines for eye protection and workpiece clamping when drilling metal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2570 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2570 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2500 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 with web thinning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eDrill Bit Material\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\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: 53873\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51732443332914,"sku":"53873","price":23.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d0ea4f8350c6b1fde3e9190d47cd83a.jpg?v=1788742821","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53873-jobber-drill-bit-letter-f-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
