Review on Irwin Tools Unibit 8 Inch Step Drill by Gary Wainwright

Thanks to my knowledge gained in practice as an industrial and scientific worker, I can confidently say that this step drill is not worth the investment. The supposed versatility and ease of use is overshadowed by its inconsistency and tendency to break easily .While it may work well for occasional hobbyists, professionals who RELY on their cutting tools daily will be frustrated with this product's lack of reliability. Save your money and invest in a more trustworthy option..
