RUKO HGB-DIN352-HSS-55° Hand Tap Set M10 x 1.5 mm, 3-Piece, HSS, DIN 352

Cutting internal metric threads by hand in steel often leads to broken taps, rough threads, or poor alignment. The RUKO HGB-DIN352-HSS-55° hand tap set solves this with three precision-ground HSS taps that guide the cut from start to finish, producing clean M10 threads in unalloyed and low-alloyed steels.

Who is it for

Machinists, metalworkers, and maintenance technicians who need reliable hand tapping for through holes or blind holes in steel workpieces up to 800 N/mm² tensile strength.

Tips

Use cutting oil and reverse the tap every half turn to break chips. For blind holes, finish with the bottoming tap to get full threads near the bottom.
