TEMO M35 Cobalt Spiral Flute 12 Size Step Drill Unibit 3/16 Inch to 7/8 Inch Plus Auto Center Punch Set

**** Customers have had a mixed experience with this particular drilling bit and punch set, indicating both advantages and challenges in their use. While the initial performance of the bit is satisfactory, excelling particularly in soft materials like mild steel, users have noted a significant drop in its effectiveness after just a few uses. The cutting efficacy diminishes quickly, leading some customers to question the value of the product, especially if they are looking for a longer-lasting solution. Users emphasize the piece’s best application is for thin sheet metal, where the versatility of adjustable diameter holes could be beneficial, minimizing the need to switch between multiple bits. There are design elements that detract from the overall experience. Users have pointed out the frustrating placement of size markings on the bit, as they are positioned upside down when installed, making it difficult to read during operation. Additionally, the markings are small and challenging to see without additional marking to assist visibility. The punch, which is meant to complement the bit, underperforms as well, with feedback suggesting that it becomes ineffective after only a handful of uses, which left users disappointed. Overall, while the product has its merits particularly for specific tasks in thin materials, the longevity and user-friendly design issues can limit its appeal, making it feel more like a disposable item than a reliable tool for serious users. **
