!Stainless Steel Shrinking Disc Combo Pack!
SD478 4 1/2" disc for Standard grinders
if you want the backing pad also, look at our other items for "KIT" in the title
!We were the FIRST to offer the smaller sized disc!
!Stronger than others, Guaranteed!
(see below, for 304 Stainless Steel mini lesson) If your not satisfied and/or you find the competitors better, then send it back and I will give you a refund! No one else offers this! Our shrinking disc is available in 4 1/2" and we have options to fit 4" and 4 1/2" grinders. It works the same as a 9" disc, but in a smaller size for ease of use for quick shrinking on small areas, areas were the big disc would not fit, and is a great addition to the SD9 9" disc!
Please take time to scan over the entire listing. There is alot of information here, and corrections to others who may be misleading.
Works just like the wavy disc, but alot cheaper!
Their kit price is about 10 times our price!!!
In the pictures I demonstrate removing two dents in a domed panel. Once I got the dents shrunk back down (I did NOT use a hammer and dolly, only the shrinking disc for demonstration purposes), I ran an DA air sander over the panel to show exactly how smooth of a finish can be achieved. You could never tell there used to be dents there. In normal conditions, you would straighten out the metal like usual with a hammer and dolly first to speed up the process and then use the shrinking disc to achieve smooth final finish.
The disc comes with detailed instructions on how to use it.
304 Stainless Steel Mini Lesson #1
Our discs are made from 304 stainless steel, despite what others may say, and they are magnetic. It is false to say that 304 is non magnetic, and is also false to say that it is a lower grade because of its magnetic properties! 304 is an austenitic alloy (non magnetic) until it is cold formed (as in cold rolling or forming), after which, it may have a very strong response to a magnet because the austenite changes to martensite (which is magnetic). After forming or rolling, it is much harder than annealed material, which gives it resistance to denting and strength that makes it stiffer. A soft or annealed 304 stainless would be prone to denting and would see much more wear and a shorter life than 304 that has been formed which results in a much harder material. If you have heard otherwise, do a Google search for "304 stainless cold forming magnetic" or something similar and I am sure you will find many sources with the same information that I have shared with you.
Watch out for other ribbed hard plastic backing pads that include a Cast nut! (I have seen them break!) Ours uses a machined nut (very important for safety!)
Watch our free video and surf the web for additional instructions on how to use the disc, No DVD needed!
Watch the short demonstration of the Shrinking Disc!

when also purchasing a planishing hammer or other large equipment!
Also Available in bulk lots for dealers or large shops.
Please Read before emailing with a question.
Q: Do your shrinking discs come with a backing pad?
Q: What type of backing pad can I use for your shrinking discs?
A: Most large grinders come with a rubber or plastic pad that is intended for flexible sanding discs, and have a nut that is tapered so it will sit flush with the surface when tightened. These work great, and can also be purchased from most autoparts, farm, tool and home improvement stores. It does not have to be the full size of the disc; it is mainly needed for mounting, as the discs have plenty of strength by themselves.
Q: I love your tool, and would like to tell you about it.
A: Great! Feel free to write a response about our tools and include pictures and/or your business/website information if you would like. If you allow permission, I will gladly post your story and link on our website for others to see how well it worked for you.
Q: What speed of grinder do I need for your shrinking discs?
A: For the 9" discs 3000-6000 rpm work great. I personally use an old heavy 6000 rpm grinder. For the 4 1/2" discs, most small grinders run at 10,000-12,000 rpm. They will work great.
Q: I paid and have not received my item, or I am unhappy because.....
Q: How do your shrinking discs compare to others on the market?
A: Many people prefer the smooth disc over the wavy disc for several reasons, it is safer with the flanged edge than the "saw blade" like edge the wavy disc has. The ridges are not necessary; they create unneeded vibration and noise. The shrinking happens because of the heat. The ridges can actually lead to premature failure and cracking due to wearing thin only on the higher area of the disc. And also is price difference. The other disc has some various sanding materials and discs included (which most shops already have) and they throw in an instructional video and they call it a kit, and charge about 10 times what we do!! My demo video is free to watch and it is so easy to learn to use, the included directions should be enough, if not, email me for further assistance.
Q: How can I learn more about metalworking and using these tools?
A: A great place to learn is the metalmeet website. Search the forums and ask questions, there are many nice people there sharing about the art of metalworking.
