Built from M42 cobalt high-speed steel and coated with titanium nitride (TiN), it delivers extended tool life in demanding applications. The 135-degree split point reduces walking and cutting pressure at entry, making it well-suited for hard or work-hardening metals. The bit measures 3-1\/4 inches overall with a 2-1\/8-inch flute length and a straight-cylindrical shank sized at 11\/64 inch. It is sold individually and is a fit for trades that require precision drilling in ferrous and stainless materials.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for drilling stainless steel and steel in fabrication, mechanical, and maintenance applications where standard HSS bits wear prematurely. The tapered web with web thinning reduces thrust load and chip packing in deep-hole scenarios. The regular spiral flute promotes efficient chip evacuation. It conforms to DIN 338 and NAS 907 Type J standards, making it appropriate for aerospace, industrial, and precision mechanical work where material traceability and dimensional tolerances matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for heat and wear resistance in hard metals\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends cutting life and reduces surface friction\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and prevents bit walking on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance in deep holes\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to -0.0007 to 0.0000 inches for precision fit\u003c\/li\u003e\n  \u003cli\u003eComplies with DIN 338 and NAS 907 Type J specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty OEM-style jobber drill bit for use in stainless steel and steel applications.

Machinists and maintenance technicians should verify spindle speed and feed rate are appropriate for cobalt bits working in stainless steel or hardened materials. Secure the workpiece before drilling to prevent movement. Coolant-through operation is not supported on this bit; use cutting fluid applied externally when drilling deep holes in hard alloys.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 11\/64 inch (0.1719 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 11\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1250 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 Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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\u003eMaterial\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2550\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 338, NAS 907 Type J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 54053\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51752658698546,"sku":"54053","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cacbea866cb2fb27e725f58a452ca167.jpg?v=1788929608","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-54053-cobalt-jobber-drill-bit-11-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
