Introduction
Shaping, smoothing, and removing material from all kinds of surfaces is the hallmark of the handy grinding disc ใบตัดใบเจียร. But just how are these abrasive marvels different? And more to the point: Does it really matter? The answer—especially if you toil over your DIY projects—is a resounding yes.
Grinding discs that are made of metal are not the same as those made of wood and should not be used interchangeably. To understand and take advantage of their differences, it is first necessary to learn what they are each intended to do and then to use them accordingly. In this article, I also discuss some associated topics like RPMs and the different textures of the two types of bulk abrasives you might consider for grinding, but the main thing to keep in mind, when you are selecting a disc, is this basic (but little-recognized) distinction between them.
Understanding Grinding Discs
- A grinding disc is an abrasive wheel that you attach to a power tool, like an angle grinder. You can think of it as a sanding disk’s grittier, meaner cousin. Doctors Eisen and Marvillet, the trouble-making duo behind “A Geek’s Curse,” explain that a grinding disc accomplishes material removal most efficiently when you use the largest grit that’s practical for the job at hand. And you can choose from different levels of “grip” for most common power tool grip types.
- Most of the grinding that we referenced here used a Zirc and a solid steel cutter, at 4,500 to 6,000 RPM.
Grinding Discs for Wood
Usually, wood grinding discs are made of silicon carbide or aluminum oxide, two types of abrasive material designed to cut through wood. Grit, which is a crucial part of any grinding disc, is what gives teeth to the disc for cutting. When it comes to grit, wood grinding discs are offered in a range similar to that of their metal counterparts. You can find them with grit sizes anywhere from 8 to 120. Ideally, when using metal, you’d want to opt for a coarser grit, and when working on wood, you’d want to use a finer grit, but this isn’t a hard-and-fast rule.
Key Differences
| Feature | Grinding Discs for Metal | Grinding Discs for Wood |
| Abrasive Material | Aluminum oxide, zirconia alumina, ceramic | Silicon carbide, aluminum oxide |
| Grit Range | Coarse to fine | Coarse to fine |
| Purpose | Cutting, grinding, finishing metal surfaces | Shaping, carving, sanding, finishing wood surfaces |
| Heat Generation | High | Moderate |
| Clogging Risk | Low | High |
Choosing the Right Grinding Disc
It’s very important to choose the right grinding disc for both safety and efficiency. There are a few key things to think about when making this decision. The first is the material—the disc has to be right for the job, and there are different ones for metal and wood. Next is the grit of the disc. This is a measure of how “coarse” or “fine” it is, and the grit you choose is based on how much material you want to take off and how much of a finished look you want to end up with. Of course, in addition to the safety and efficiency of the disc, you need to make sure you’re using the right safety gear and following other safe work practices.
Conclusion
It is crucial for any do-it-yourselfer or professional to know the distinctions between grinding discs for metal and wood. This is because those who choose the incorrect grinding disc for the task at hand run the risk of poor performance, an unsafe work environment, and even damage to their tool or to themselves. Hence, it is well worth the few moments it takes to choose the right grinding disc. After all, using the correct one is the first step to getting the “pro” look for your project.
