Built from cobalt high-speed steel with a gold finish, these bits deliver superior heat resistance and edge retention when cutting through hard metals, stainless steel, and abrasive alloys. The 135-degree split-point tip reduces walking on contact and requires no center punch for accurate hole starts. Straight shanks fit standard drill chucks, and right-hand cutting geometry is compatible with conventional drilling equipment. This set is a working-trade staple for HVAC techs, pipefitters, electricians, and sheet metal mechanics who need reliable performance across a range of hole sizes in a single case.\u003c\/p\u003e\n\u003cp\u003eThe 69856 covers hole diameters from 1\/16 inch to 1\/2 inch in 1\/32 inch step increments, providing 15 graduated sizes in one organized storage case. The screw machine length profile — shorter than standard jobber length — gives added rigidity and reduces deflection when drilling in confined spaces, tight enclosures, or on drill press fixtures. Intended for metalworking and multipurpose drilling tasks, this set suits both production shop environments and field service use where a broad size range must be on hand without carrying multiple individual bits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for high heat resistance and extended tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split-point tip eliminates walking and reduces required feed pressure\u003c\/li\u003e\n  \u003cli\u003eGold finish applied for surface hardness and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides added rigidity over standard jobber length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, straight shank compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003e15-piece set in 1\/32 inch increments from 1\/16 inch to 1\/2 inch in a metal or plastic storage case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-shank drill chucks on portable drills, drill presses, and milling machines used in metalworking and multipurpose drilling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the workpiece firmly before drilling and ensure the drill chuck is tightened to rated holding capacity. Use cutting fluid or coolant when drilling hard or stainless alloys to extend bit life, even though these bits are rated for dry cutting. Inspect shank and cutting edges for damage before each use. Discard any bit showing cracking, excessive wear, or heat discoloration past the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold Finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Bit Size\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Bit Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStep Increments\u003c\/strong\u003e: 1\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 559\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStorage Unit Material\u003c\/strong\u003e: Metal or Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStorage Unit Type\u003c\/strong\u003e: Case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Metalworking, Multipurpose Drill Bits\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: 69856\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51750195560754,"sku":"69856","price":236.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e89b71ef4ab2d64d4ab88813ee811ea4.jpg?v=1788914236","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-69856-cobalt-drill-bit-set-15-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
