The DIN352 standard hand tap set consists of three taps and it will significantly reduce the risk of breakage by using them correctly. 


The character of three-piece hand taps is that the individual parts of a set share the cutting power: 

The taper tap (No. 1) has a pilot nose and ensures that vertical threads are always cut. It removes 65 percent of the thread profile, while the intermediate tap (No. 2) (marked with two rings) removes 85 percent. Pre-cutting and reworking with the intermediate tap (No. 2) bring the thread into shape. Finally, the bottoming tap (No. 3) is used, which has no ring marking. Only this cuts the full and usable thread at the end. 

The division of labour between the three screw tap makes it easier to cut a straight and clean thread by hand.


Hand taps cut internal thread by hand with tap wrenches, ratchet holders or other holding tools with square drive.


The thread can be cut in a pre-drilled core hole.


Due to the short chamfer of the bottoming tap, the hand tap set can be used universally for through holes and blind holes.


Application: wear resistant steel up to 1400 N/mm²- high alloy steel- heat resistant steel- stainless steel- alloy tool steel- cast iron.
