Got a left-hand threading job? This M17 x 1.0 tap and die set is made for that. The tap is high-speed steel with a straight flute design—good for through holes or shallow blind holes in stuff like brass, copper, steel, or aluminum. The die is alloy tool steel, great for fixing or cutting external threads. They’re both left-hand cut, so just match the rotation. Use them with a drill, lathe, or by hand (go slow on hard materials). Tip: add some lubricant when cutting, and back off every half turn to clear chips. Comes as a set—one tap, one die. If you're into metalworking, repairs, or machining, this is a handy pair to have around. Just remember: lefty loosey, righty tighty… wait, reverse that for left-hand threads! Double-check your specs before starting.
