The biggest reason to buy is the variety and hardness of the M35 cobalt bits, which make it possible to tackle stainless steel, cast iron and other tough materials without constantly swapping specialty bits. Our review found the set best suited to general metalworking and mixed-project use rather than heavy industrial production.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComprehensive size range:\u003c\/strong\u003e The 100 pieces include multiple small sizes and larger sizes from 3\/64' to 3\/8' so users rarely need to buy an extra bit for common drilling tasks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM35 cobalt construction:\u003c\/strong\u003e The M35 material keeps cutting edges harder and more heat-resistant than plain HSS, helping when drilling stainless steel and hardened parts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e135 degree point tip:\u003c\/strong\u003e The split 135 degree point helps with fast chip removal and self-centering to reduce walk-off when starting holes in metal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJobber length design:\u003c\/strong\u003e The standard jobber length balances rigidity and reach for general drill press and handheld drill work without excessive wobble.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndexed storage case:\u003c\/strong\u003e The included case has size indexing that keeps bits organized and protected, making it straightforward to find the size you need on the job.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe set is ideal for hobbyists, home workshop owners and trade professionals who need a broad selection of sizes to work on stainless steel, cast iron, aluminum, copper, wood and plastics.
