Got an Astro Pneumatic tool 1442 or 1452? Need to replace a worn-out part or add a new thread size? This mandrel and nose piece pair is here to help. Sold together because you really need both to make it work – the mandrel and the nose piece team up to let your tool handle 5/16-18 nuts. It's a straightforward way to expand what your tool can do or just fix it up if something got lost or broken. The package is pretty small (about 2.7cm x 9.6cm x 22.3cm) and lightweight at half a pound, so shipping's easy. Made in China, like a lot of handy tool accessories. No frills, just functional. If your tool didn't come with this size originally, here's your chance to add it. Keeps your work moving without buying a whole new tool. Simple, effective, and exactly what you need for those specific nut jobs. Just pair it with your Astro Pneumatic tool and you're good to go.
