Review on πŸ’ͺ Power Punch Heavy Duty: The Ultimate Tool for Unstoppable ABN Performance by Ronald Lunn

Revainrating 4 out of 5

Does the job

Benefits* Decent hole size range; Note that they are actually metric and not imperial* Easily change punches and dies; I replaced them by hand, no additional tools are required. * Easily adjust the die height for easy cleaning of stamped metal after each operation. ie you might have to put in a little effort, but you can get it back in 15 seconds or less* Can actually penetrate at least up to 16 gauge; I punched through 304 stainless steel sheet metal, which required quite a bit of tools, but I was actually able to do it with a little help (a vise). Disadvantages * No registration marks on the die head; makes stamping and sheet metal alignment less accurate than it should be; to me this is a major oversight; Since the main body of the hammer drill is cast steel, this may need to be machined after casting, but that's not a big deal as they already do other post-casting steps (e.g. tapping) * The depth of throat adjustment is a bit inaccurate; need a screwdriver to tighten enough - it would be better to have a thumbscrew or wing nut; Also when tightening it tends to tilt in the direction you tighten it - nothing prevents it from tilting and then you get more than 0.1" of variability when you push the piston against it (piston angle of attack ).determines how many variations you will see) *Grip material is not very durable; I managed to rip it on both grips the first time I used it (I remember checking the punch limits with 16- 304 SS gauge sheet metal) Having calipers on hand is not a major disadvantage Relatively modest price For softer steel (like 20 gauge galvanized sheet metal) this stamp works very well 4 out of 5 stars due to lack of registration marks on the stamp head and suboptimal Fillet Depth Adjustment Without these fiducial marks, it will be more difficult to line up the stamp exactly where you want it.

Pros
  • Great for a small home
Cons
  • I vaguely remember
