Do Your Best Grinding With Walter Metal Hub Grinding Wheels

When grinding, you need a lot of power and a lot of strength to do extremely fine, or delicate work on some of the toughest materials in the world today. Expending vast amounts of heat on two pieces of metal creates a lot of extra mess, but even so, it still needs to be cleaned up and removed. This is why grinding is so important, and this is why when you need it done right, you go with something like the 08-B-455 HP Grinding Wheel by Walter.

The Walter Story

During the 1950s, in the Montreal suburb of Pointe-Claire, there lived a man named Walter Somer. He had an ambition, and that was to improve the tools of the tradesmen of French Canada. He started up a company to realize that ambition and fortunately, he was right. The reputation of his tools quickly spread beyond Quebec to the rest of Canada, and then even America.

Now, that company, called Walter Surface Technologies, is a multinational corporation with offices in different parts of the world. Innovation and improvement continue to be key principles of the company, with new tools and accessories setting new industry standards in safety, efficiency and cost effectiveness. Many different processes enjoy Walter’s careful eye for improvement, including metal working. The Walter 08-B-455 Grinding Wheel is a perfect companion for people that need to do good work with speed and comfort.

Improve Your Steel Grinding Work

The 08-B-455 HP is a 4½” grinding wheel that is designed for the tough jobs. The “HP” stands for high performance, and it means that when you’ve got a difficult piece to work with, the handling and comfort of this wheel come first, to make sure that you do your job without fighting the tool. The highest quality abrasive grains were mixed with increased wear resistance to give a combination of both power and longevity. You can work faster, but the wheel can last longer, and when you put the wheel in place, it stays where you want it and feels comfortable and easy to use.

The 08-B-455 HP has the usual high rate of removal that other Walter products do, making it one of the best in the industry, but it will last a very long time before needing to be replaced. When the time comes, switching the wheel out is easy, thanks to the convenient spin-on design. It can handle many different activities, so whether you need it for shaping, deburring, grinding welds or preparing weld edges, it’s ready to get your job done. If you want something for cast iron or steel work, this is it.
