This chamfering tool is exactly what I needed for my metalworking projects. The smooth, clean cut it produces is unparalleled and the degree of precision is impressive. Plus it`s made with durable and high-quality materials. The only downside is that it can be a bit pricey compared to other industrial drill bits, but it's definitely WORTH the investment .Overall, a great addition to any workshop or industrial and scientific setting..
Pros
Efficiently creates precise tapered holes and chamfers with its 90-degree point angle and 3-flutes design.
Cons
Requires specific drill bits to use, limiting its compatibility with different power tools.
They don't cut at all. You smear the material to the side, but then it takes a bit more to remove. I have several types of deburring tools and these are by far the WORST I've seen.
