Each bit is crafted from cobalt-infused M35 high speed steel, delivering a balance of hardness and durability for a range of metals and tough plastics. The bits arrive in a clear plastic case that keeps the set neatly organized for quick access on the job site.\u003c\/p\u003e\n\u003ch2\u003eWhy these bits stand out\u003c\/h2\u003e\n\u003cp\u003eCompared with standard HSS options, the cobalt content enhances edge retention and wear resistance, helping you work through harder materials with less frequent bit changes. The manufacturing process emphasizes precision, with multiple grinding and hardening steps that help maintain a tight diameter tolerance. The result is a reliable tool that can support consistent hole sizes across multiple entries.\u003c\/p\u003e\n\u003ch3\u003eKey design and performance features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split-point reduces wandering and starts holes cleanly on tough surfaces.\u003c\/li\u003e\n  \u003cli\u003e5% cobalt content (M35) contributes to improved hardness and heat resistance during drilling.\u003c\/li\u003e\n  \u003cli\u003eSuitable for hardened metal, stainless steel, cast iron, as well as durable plastics and PVC boards.\u003c\/li\u003e\n  \u003cli\u003eDiameter accuracy controlled within a tight tolerance to support repeatable results.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePractical uses and scenarios\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMetalworking: drilling into hardened steel, stainless steel, and cast iron for fixtures and brackets.\u003c\/li\u003e\n  \u003cli\u003ePlastic and PVC projects: reliable starts in resistant plastics and composite boards.\u003c\/li\u003e\n  \u003cli\u003eWoodworking: through-holes and pilot holes in various woods for fasteners or joinery.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eStorage and care are straightforward thanks to the included plastic case, which helps you keep the bits organized and protected between jobs.
