Specifications for Best Sheet Metal Seamer
Before going on to the reviews it’s a prerequisite that you’ve accumulated some knowledge as to what might cause the sheet metal seamer to be futile or boost its utility and durability. Let’s overview the attributes thoroughly.
Sheet Metal Seamers have to deal with a large number of force to bend or form metals. So if its construction material does not consist of high-quality materials then the rivets will eventually break off. Sometimes the handle also breaks off due to the same reason.
A metal or steel body is a must if you are going to purchase any seamers.
Build quality & durability go hand in hand. The better the material being used; the more years the tool will serve you. But some small details really make a lot of differences. Like a finishing ointment on the material can prevent any sort of rust attacking the metal or steel.
Sheet Metal Seamers are hand tools, that you will be operating a lot if you are in the HVACR industry. So if you are working with a heavier tool, your hands will tire off soon. This degrades the efficiency of your work. Rather a lightweight seamer will give lesser stress to your hands as well as getting more work done.
Jawline length is one of the main features of a seamer. If your work depends on a larger jawline, then you can go for the 6-inch seamers. But if not then the 3-inch seamer will do you fine. Keep in mind that a larger jawline means more force to apply.
Jaw depth is also important as this will determine how much steel sheet can you bend. The larger the jaw the larger the depth of steel you can bend. But this comes at a cost as you have to apply more force to the steel. If there are alignment marks on the clampers, then it helps in fixing the desired line of steel you are bending.
You will be working on the handle a lot. So it is necessary that the handle has a rubberized grip. Bruises are just a couple of working hours ahead if you think bare hand working with seamers is not an issue. Without a grip the handle can even slip from your hand, causing accidents.
