Built from cobalt high-speed steel with a gold finish, these bits deliver extended heat and wear resistance compared to standard HSS tooling. The 135-degree split-point tip starts on contact without a center punch, reducing walking and improving hole accuracy. All 60 bits feature straight shanks and right-hand cutting direction. This set covers wire gauge sizes 1 through 60 and is suited for production environments, maintenance shops, and tool rooms where consistent performance across a full wire gauge range is required.\u003c\/p\u003e\u003cp\u003eThis set is engineered for metalworking and multipurpose drilling tasks in both production and general maintenance settings. The screw machine length design provides a shorter, stiffer profile than jobber-length bits, which improves rigidity and reduces deflection in drill press and CNC applications. The full wire gauge range from 1 to 60 makes this set practical for machinists, maintenance technicians, and fabricators who regularly drill tapped holes, clearance holes, and precision fits in steel, stainless, cast iron, and other hard materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction for high heat and wear resistance in hard metals\u003c\/li\u003e\n\u003cli\u003e135-degree split-point eliminates center-punching and reduces walking at startup\u003c\/li\u003e\n\u003cli\u003eGold finish applied to all 60 bits in the set\u003c\/li\u003e\n\u003cli\u003eScrew machine length profile provides added rigidity over standard jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight shank, right-hand cutting for use in standard drill chucks and CNC toolholders\u003c\/li\u003e\n\u003cli\u003eFull wire gauge range from 1 to 60 stored in a metal or plastic case\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill presses, CNC machining centers, and hand-held drills equipped with standard straight-shank chucks.

Secure the straight shank firmly in the chuck and verify runout before beginning a drilling operation. Use appropriate cutting fluid or coolant for the workpiece material to extend bit life. Follow applicable OSHA and shop safety standards when operating drilling equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 559\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range (Wire)\u003c\/strong\u003e: 1 to 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt High-Speed Steel\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eStorage Unit Type\u003c\/strong\u003e: Case\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\u003eTool Application\u003c\/strong\u003e: Metalworking, Multipurpose\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: 69854\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51738728137010,"sku":"69854","price":366.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/223941fcddbedd39b1e862815f8f4cfe.jpg?v=1788803526","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-69854-cobalt-drill-bit-set-60-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
