These things are JOKE, I've tried using 1/8 and 3/32 on two small roller pins that are the right size for the job and though the roller pins were well greased, both punches were "bent" like they were tin, I ended up using my neighbor (65) "Sears & Roebuck - Made In The USA" roller pin puncher the same size as above used and successfully driven both pins out with minimal effort, I'm returning them and buying a temper hardened set that I can rely on and pass on to my grandchildren when I'm gone. You get what you pay for.
