The biggest reason to consider this set is the inclusion of M35 cobalt bits in 115 sizes, which provide greater hardness and heat resistance than ordinary HSS for tasks on stainless steel, cast iron and other tough metals while remaining useful for wood and plastics.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComprehensive size range:\u003c\/strong\u003e The set includes 29 fractional sizes, 26 letter sizes and 60 numbered sizes so users rarely need an additional bit when working on varied projects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM35 cobalt construction:\u003c\/strong\u003e The M35 alloy offers improved hardness and heat resistance for drilling through stainless steel, iron castings and other hardened metals without rapid wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e135 degree point tip:\u003c\/strong\u003e The split-point geometry is self-centering to reduce walk-off and speeds initial penetration for cleaner, more accurate holes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJobber length design:\u003c\/strong\u003e Standard jobber length provides a good balance of reach and rigidity for general purpose drilling in both metal and non-metal materials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndexed metal storage case:\u003c\/strong\u003e The compact metal index storage box keeps bits organized by size for faster selection and safer transport between jobsites.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe Cobalt Drill Bit Set is best for mechanics, metal fabricators, and DIYers who face a mix of materials and need durability when drilling hardened or stainless steels.
