Forged from top-grade High-Speed Steel (HSS), these combination bits exhibit outstanding structural hardness, superior wear resistance, and high thermal stability, ensuring the cutting edges stay razor-sharp under demanding workshop conditions.

The comprehensive 5-piece kit covers the most frequently used metric thread sizes—M4, M5, M6, M8, and M10—effectively replacing multiple separate drill bits, hand taps, and deburring tools to drastically maximize job site efficiency and reduce tool changeover time.
