It is built from M42 high-speed cobalt steel, a material grade that retains hardness at elevated cutting temperatures. The 135-degree split point self-centers on contact, reducing the need for a center punch and minimizing walking on hard surfaces. The TiN coating lowers friction and extends edge life compared to uncoated cobalt. This bit is suited to production drilling and maintenance work where tool longevity under repeated use is the primary concern.\u003c\/p\u003e\n\u003cp\u003eThe 54045 is intended for drilling stainless steel, alloy steel, and other ferrous metals where standard HSS bits wear prematurely. At 2-5\/8 inches overall length with a 1-1\/2-inch flute length, it fits standard three-jaw drill chucks and is sized for benchtop drill presses, hand drills, and magnetic-base drills used in fabrication shops, mechanical rooms, and field service work. The straight-cylindrical shank diameter of 0.1100 inches seats securely in chucks rated for that range. The Series 2550 designation places it within Chicago-Latrobe's heavy-duty cobalt line built to DIN 338 and NAS 907 Type J standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for heat resistance during high-speed drilling in tough alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point self-centers and reduces thrust force on entry\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends service life\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance through the full flute depth\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix efficiently clears chips from the hole\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J specifications for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length replacement or production drill bit for applications requiring a No. 35 wire-gauge hole (0.1100 inches) in stainless steel and steel workpieces.

Secure the straight shank firmly in the chuck before use and verify the workpiece is clamped to prevent rotation. Use appropriate cutting fluid when drilling stainless steel to manage heat buildup and extend bit life. Inspect the cutting edges before each use and replace the bit when chipping or edge rounding is visible to maintain hole-diameter tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt (M42)\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 Helix\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\u003eFinish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1100 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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\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\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 54045\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51748301242674,"sku":"54045","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65c34eddd76d569c1db6aeba8ea96f6e.jpg?v=1788892028","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-54045-cobalt-jobber-drill-bit-no-35","provider":"Voomi Supply","version":"1.0","type":"link"}
