Based on my experience with this product I am pleased to say that it is a great tool for industrial and scientific applications... The design is efficient and user-friendly, making it quick and easy to center and pre-drill holes exactly where they need to be. One downside is that it might not be ideal for smaller, more delicate projects. Overall, this is a highly recommended product for anyone in need of a quality centering pre-drill bit for their cutting tool collection..
Pros
Ensures accurate centering of drill bits for precise holes.
Cons
May cause damage to the material if not used properly.
After i put it to the test, this tool proved to be a waste of money .It did not center on the spot I marked and could not make a clean hole. The only positive thing is that it is compatible with other drills. However, with its poor performance, it's not worth buying..
Pros
Helps to accurately center the drill bit for precise drilling.
Cons
Some users may find the product difficult to use without proper instructions.
This is definitely not what is shown online. (1) Instead of a twist drill as shown in the picture, it comes with a cheap blade drill. (2) It should have been a self-centering drill. In the end, this nozzle did not have the chamfer necessary for self-centering. It's kind of a fake vix. Piece of shit.
