Machinists and serious metalworkers, this Starrett Spindle Square is one of those tools that'll save you hours of frustration and give you perfect results every time. Tramming your milling machine head is crucial for accuracy, and this tool makes what used to be a tedious process quick and precise. With two AGD Group 2 dial indicators, you can check alignment in both X and Y axes simultaneously - no more guessing or repeated adjustments. The patented design is genius - the 3/8 inch shank fits securely in your collet, and the solid steel construction means it stays accurate through years of use. The black oxide finish isn't just for looks - it protects against rust and makes the tool easy to clean. The .250 range gives you plenty of measurement capability for even larger machines. What used to take multiple setups and lots of back-and-forth now takes minutes with consistent, reliable results. The build quality is exactly what you'd expect from Starrett - everything feels precise, movements are smooth, and the dial indicators are crisp and easy to read. Whether you're setting up for a production run or doing one-off precision work, this tool ensures your spindle is perfectly perpendicular to your table. One of those shop tools that pays for itself in time saved and scrap avoided.
