User questions & answers

Question:	can this be used with a manually with just a wrench on an occasional basis
Answer:	These are definitely metric . Greenle is standard and they so not work together
Question:	Will this work on a sink
Answer:	Amazon sells the threaded draw studs . They are metric threads. I haven't seen the knock out dies sold separately though. You may have to contact the seller.
Question:	For the 2" model, what size hole must be pre-drilled for the draw stud
Answer:	No
Question:	Is the finished hole 1 1/2 inch or slightly bigger
Answer:	Don't know about ideal but be careful with greenlee. The threads are slightly different and I actually ruined both of the studs that came with the kit trying to use.

User questions & answers

Question:	Will "normal industry standard draw studs" fit? Does it have a case
Answer:	I do not know for sure, but the cutting edges on the units are not severely sharp, so I would not recommend it. I think the plastic might break or not cut very cleanly. Try using a drill with a step bit (or graduated bit as they are called sometimes).
Question:	What company makes this tool
Answer:	Si es para electricista. Saludos.
Question:	What is the tonnage punch strength? 6 ton, 10 ton, 15 ton
