Machinists, mechanics, and metalworkers – this set of metric HSS spiral flute machine taps is exactly what you need for creating clean, precise threads! Made from High-Speed Steel (HSS), these taps are built to handle tough materials like steel, stainless steel, and other metals without dulling quickly. The spiral flute design helps efficiently pull chips out of the hole as you tap, reducing the risk of breaking and giving you smoother threads. This set covers a range of metric sizes from M2 (small) up to M24 (quite large), making it versatile for various projects. Whether you're working on automotive parts, machinery, fabrication, or DIY metal projects, having the right tap makes all the difference. These are machine taps, meaning they're designed for use in drill presses, lathes, or tapping machines, but can be used carefully by hand too. Made in the United Kingdom, so you can expect decent quality even though they're unbranded. Always remember to use cutting fluid and the correct drill size for the tap you're using. A must-have for any well-equipped workshop. Keep your threading jobs professional and hassle-free with these durable HSS taps!
