I recently purchased a 16 inch titanium split drill bit from the Cutting Tools category in Industrial and Scientific. After I put it to the test, I must say I am impressed with its performance. The bit easily sliced through metal sheet without any bending or breaking. The titanium coating ensured that it remained sharp and durable for numerous projects. The only downside is that it may not be suitable for smaller scale DIY projects due to its size. Overall, I am extremely satisfied with this industrial drill bit.
