The ratchet tap holder is suitable for taps from 5 to 12 mm. Its 3-position ratchet mechanism allows for left- or right-handed use, as well as a fixed position, thus offering high flexibility.
Taps and dies are essential to make or re-thread a screw, a nut or any other mechanical element. The three-piece tap sets are the most commoly used and the tap wrench is as important as the die stock for a proper tapping. Drilling is required before tapping.
