Built from cobalt steel with a gold finish, this Series 550 set covers a metric size range from 1 mm to 10 mm in 0.5 mm step increments. Each bit features a 135-degree split-point tip for fast, self-centering starts that reduce walking on hard or smooth surfaces. The straight shank design seats in standard drill chucks without adapters. At 2 pounds, the full set ships in a metal storage case. This set is suited for machinists, maintenance technicians, and fabricators working with steel, stainless, cast iron, and other ferrous and non-ferrous metals.\u003c\/p\u003e\u003cp\u003eThis set is configured for metric drilling applications across a wide size range in a single case. The 19 sizes span 1 mm through 10 mm at 0.5 mm intervals, making it a practical choice for shops that work to metric engineering drawings or service metric-dimensioned equipment. Typical applications include through-hole drilling, clearance holes, and pilot holes in metalworking, general fabrication, and maintenance environments. The cobalt construction extends tool life when drilling harder alloys and work-hardened materials compared to standard high-speed steel bits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt steel construction for extended life in hard and abrasive metals\u003c\/li\u003e\n\u003cli\u003e135-degree split-point tip for self-centering starts and reduced thrust\u003c\/li\u003e\n\u003cli\u003eGold finish for corrosion resistance and visual wear indication\u003c\/li\u003e\n\u003cli\u003e19 metric sizes from 1 mm to 10 mm in 0.5 mm step increments\u003c\/li\u003e\n\u003cli\u003eStraight shank fits standard drill chucks; 10 mm maximum shank diameter\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; jobber length geometry for general-purpose reach\u003c\/li\u003e\n\u003cli\u003eMetal storage case keeps bits organized and protected between uses\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in metalworking and multipurpose drilling applications where metric-sized jobber length cobalt drill bits are required.

Ensure the drill press or handheld drill is powered off and de-energized before changing bits. Use appropriate cutting fluid or coolant when drilling hard ferrous metals to preserve bit life; this set does not support internal coolant-through delivery. Follow established shop safety practices including eye protection and secure workpiece fixturing before beginning any drilling operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 550\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 19\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold Finish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split-Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Bit Size\u003c\/strong\u003e: 1 mm (0.0394 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Bit Size\u003c\/strong\u003e: 10 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep Increments\u003c\/strong\u003e: 0.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Jobber Length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Metalworking, Multipurpose Drill Bits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage Unit Type\u003c\/strong\u003e: Metal Case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 47924\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51972001595698,"sku":"47924","price":195.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fcbc35d0115ed485c6c43420db550d00.jpg?v=1789960521","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-47924-cobalt-drill-bit-set-19-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
