Hey contractors and DIYers! This steel stud crimper is exactly what you need for those ceiling and drywall projects. It's specifically designed for fixing light steel keels with wall thickness between 0.5-0.8mm - you know, the standard stuff you work with every day. The full length is about 310mm (that's 12.2 inches for my imperial friends) with pliers width around 55mm. The non-slip handle makes it comfortable to use even during long installation sessions, and it seriously saves time and effort compared to other methods. It's made from excellent steel forging that gives you both high hardness and good toughness - this thing can take some abuse on the job site. Perfect for ceiling work, plant construction, or any project involving light steel framing. The punching range is approximately 0.3 x 0.8cm, and it's so simple and labor-saving that it actually makes a good replacement for rivets in many applications. Whether you're a professional contractor tired of struggling with inadequate tools or a serious DIYer tackling home renovation projects, this crimper will make your life so much easier. The handle length is about 125mm, giving you good leverage without being too bulky. It's one of those tools that once you use it, you'll wonder how you managed without it. Just a heads up - the new type and old type get sent randomly, but both work great. Seriously, if you're doing any steel framing work, this tool is worth every penny for the time and frustration it saves.
