If your drill press quill isn't returning properly, these replacement springs will get it working like new again! This 3-pack gives you plenty of spares for future use or multiple machines. Each spring measures 0.8mm thick, 8mm wide, and extends to 680mm long (about 26.77 inches) with a 36mm outer diameter. They're made from quality spring steel (60Si2Mn) that's built to last, with a chemical blackening finish that helps prevent rust. The hook mounting design on both ends makes installation relatively straightforward, though you do need to be careful during setup. Important safety note: don't loosen the wire that's holding the spring coiled during shipping! You install it with the wire still in place, and it'll slide out once the spring is properly seated. This spring is what returns your drill press quill to the top position after drilling, making your work much smoother and more efficient. They work for various drill press models and can also be used for other applications like vacuum cleaners, safety mechanisms, and other equipment needing reliable coil springs. Having three means you're set for a while, and the quality is noticeably better than cheap alternatives.
