CHEMITOOL CUTTING Hand Taps Set Metric Fine M18 - DIN2181

The set of CHEMITOOL fine thread metric taps in high-speed steel were developed with the aim of providing the user with a good quality product with a constant work performance during the thread opening process.The CHEMITOOL fine thread metric tap set is used manually to open fine metric threads. Normally it should be used in a scaled manner, that is, following the cutting process, starting with the metric roughing tap (1 ring), ending with the final finishing/grinding tap.This type of metric taps were manufactured for the manual production of metric ISO fine threads in accordance with DIN13 standard in through and blind holes in steel, non-ferrous metals with a hardness of 800 N/mm2.
The thread pitches of metric taps comply with tolerance class 6H.Metric taps have a square-shaped fitting (according to DIN 10), to be firmly held in the adjustable or ratchet-shaped screwdriver, thus preventing springing when torsional forces are being exerted.
