Size: 51. Package of 10. Made of high speed steel. Drills accurate holes. Great for drilling ferrous metals, tough casting sand forgings, working hardened stainless steel, and more.
This product was a COMPLETE disappointment. Despite being marketed for industrial and scientific use, the performance was subpar. The drilling process was slow and the bits had a tendency to break, causing delays and additional costs. .
After trying this drill bit i was left disappointed... The pros are that it is made of durable material. However, the cons outweigh the pros as the drill bit wasn't able to cut through materials as smoothly as other ones in the market. Overall, this product is not worth the investment..
Pros
Sharp and durable, providing clean and precise holes in various materials.
Cons
Requires periodic maintenance to keep the drill tip in optimal condition.
