Hey machinists and metalworkers, this is a classic tool you need in the shop! It's a HAWK brand Universal Scribing Block, also called a Surface Gauge. It's the large size, perfect for marking out precise lines on your workpieces. The base is a solid steel block measuring about 3-1/8\ x 2-1/2\, so it's nice and stable. You get TWO interchangeable spindles: a 9-inch one and a longer 12-inch one, both with a 3/8\ diameter. The spindle holds a scriber (not included) that you can adjust up and down and lock in place to mark consistent heights from your surface plate. This is a brand new tool, made in India, and it comes ready to go. Whether you're laying out parts for drilling, checking parallelism, or doing any kind of precision layout work, a good scribing block is essential. It's a simple, timeless tool that gets the job done right. If you're setting up a home machine shop or need to replace an old one, this HAWK model is a reliable and affordable choice.
