Based on my observations, this drill bit was not able to perform even the simple task of countersinking... It failed to cut through basic materials like wood and metal. The one positive is that it is part of the Industrial and Scientific category but that does not make up for its lack of functionality. Save your money and look elsewhere for a better option..
Using this DRILL, our workshop team found that we could quickly and effortlessly drill countersinks into various materials, from wood to metal.The drill is powerful and durable with a long lifespan. However, it may take some time to master the proper drilling technique initially. Overall, a great investment for any industrial setting needing high-quality cutting tools..
Pros
Produces a clean and precise countersink hole.
Cons
Requires a separate drill bit for use, increasing overall cost and storage needs.
Ideal for countersink drilling. Very sharp and found that when using a dull drill bit when the countersink hits the back of the cabinet it almost goes through the back. Cuts very well.
