Measuring 9\/64 inches (0.1406 inches decimal) in diameter with a 135-degree split point, this bit cuts aggressively with less feed pressure than a conventional 118-degree point. The titanium nitride (TiN) coating adds surface hardness and heat resistance, extending tool life in demanding production and maintenance drilling applications. At 2-7\/8 inches overall length with a 1-3\/4 inch flute length, the 54051 fits standard drill chucks without modification. It is suited for machinists, fabricators, maintenance technicians, and HVAC and plumbing professionals who regularly work with corrosion-resistant alloys.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for use in metal fabrication shops, mechanical rooms, and field service environments where stainless steel and high-alloy steel are common workpiece materials. The Series 2550 design meets DIN 338 and NAS 907 Type J standards, making it appropriate for aerospace-adjacent, industrial, and commercial mechanical applications. It is sold individually and fits into standard jobber-length drill sets and power drill equipment. Professionals drilling through pipe flanges, structural stainless components, or sheet metal assemblies will find this bit well-suited to the work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction resists heat buildup when drilling stainless steel and hard alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers thrust required at bit entry\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and extends cutting life\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves chip evacuation and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for standard drilling operations\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J standards for dimensional and performance compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length replacement or addition for use with any standard straight-shank drill chuck accepting a 9\/64-inch diameter bit.

Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation. Use appropriate cutting fluid or lubricant when drilling stainless steel to manage heat and preserve coating life. Inspect the cutting edges before each use and replace the bit if chipping or dullness is observed, as a worn bit increases heat and can damage workpieces.\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\/64 inches (0.1406 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9\/64 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: Cobalt (M42 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\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: 54051\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51748679745842,"sku":"54051","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/977e83505ec8b5fb12db1f6cb5e83d2c.jpg?v=1788896579","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-54051-cobalt-drill-bit-9-64-in-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
