General description A Sherwood Spiral Point Tap is designed for creating threads in metal with efficiency. Its chiselled point pushes metal chips ahead of the forming threads, making it ideal for tapping through-holes. However, it is not recommended for blind holes due to the risk of chip accumulation that can bind and break the tap.
