I have several sets of Allen wrenches in both SAE and Metric. Often times the oddballs are Metric but sometimes they are just oddballs that defy common wrenches.
I prefer Bondhus and Eklind allen wrenches for standard and T-handle use. I have lots and lots of Brownell’s Magna-Tip inserts, as well as German made Wera and Wiha.
For decently priced digital calipers, look on Amazon for iGaging brand. They are good calipers for a good price. I use Mitutoyo mostly but they are fairly expensive. I bought iGaging calipers for a demonstration and like them. I also have an iGaging digital depth gage that is very good quality for the price.
