A left and right handed spiral knurl pair - producing a fine diamond pattern (Pitch = 0.029") .
Provides a comfortable and elegant grip for many jobs. Hobbed and hardened in HSS, these British made knurls have honed bores.
PLEASE NOTE: FOLLOWING HUGE DEMAND FROM RECENT YOUTUBE BUILDS, THESE KNURLS WILL TAKE AROUND 6 WEEKS TO ARRIVE... IF YOU ARE ORDERING THEM TOGETHER WITH ONE OF OUR KNURLING TOOL KITS, WE WILL SEND THE KIT "QUICKLY" AND THE KNURLS "ASAP". SORRY FOR THIS AGGRAVATION.
