Organised in all the way – thanks to the included practical plastic storage box, your countersinks are always perfectly organised and easy to store.
Long service life – particularly high hardness, enormous wear resistance and heat resistance up to 600 °C thanks to a titanium nitride coating and high-performance high-speed steel (HSS) produced according to ISO 4957-HS.
