FWIW: Bought a set of the exact same I believe Krisso Mate a few years ago for personal kit work & play and reckon you’ll be very happy hopefully too with them for their price [emoji106][emoji106]
I’ve almost flogged out the 19mm on little Hilti concrete studs via a cordless rattle gun but will just simply cut say 20mm off its end for another happy fresh stint [emoji123][emoji23]
EDIT: 19mm
