Grinder bits are designed in different grits to cater to diverse needs. But how do you determine which grit would be the most effective for your specific requirements? For now, we are going to focus on GRIT! Here's some valuable information to help you choose the right bit for your project.
First, what is in a grinder bit? The illustration is quite simple, the outer layer is actually diamonds!! Next is the Nickle followed by the Nickle plating, and then the core. Let’s move on.
Have you ever shopped for sandpaper and noticed the various textures available? These textures are actually referred to as "grit" and they determine how coarse the sandpaper is. The coarseness is determined by the size of the abrasive particles present on the surface of the sandpaper. When choosing a grinder bit for your project, it is crucial to pick the appropriate grit for the task at hand. Opting for a grinder bit that is too rough can result in your glass edges being left scratched or chipped. On the other hand, selecting a bit that is too fine may not effectively complete the job, leaving you stuck grinding away endlessly.
If you're dealing with tough materials like a highly textured glass and need to remove a lot of glass material quickly, a 60 grit speed bit or production grinding head is your go-to tool. It's designed to rip through those hard surfaces a little faster than the standard bit. Just keep in mind that the finished edge might be rough, so you can switch to a finer grit bit afterwards for a smoother finish. Hint: It's always helpful to have a couple of grinder bits on hand, each with different grit levels, to ensure you achieve the desired smoothness in your finish.
But why so many grinder bits?
If you're just starting out with stained glass, it's common to encounter pieces that need a significant amount of grinding to reach the edge of your pattern.
To make this process easier, it's a good idea to identify all the pieces that require extensive grinding and use a lower grit grinding bit. This will help you quickly remove excess glass and get closer to the edge of your pattern. By doing this for all the pieces that need it, you'll save a lot of time and effort and will certainly extend the life of your bits with finer grit.
Lets Talk About Grit:
220 Grit: When it comes to grinding, using fine grit will result in a slower process, but it will give you a much smoother finish. This type of grit is perfect for grinding delicate glasses like window glass, mirrors, or antique glass. It is also ideal when the ground edge will be visible and not covered by foil or lead.
100 Grit: These are the most popular bits. 100 grit is the best combination for speed and smooth finish.
60 Grit: If you're looking for a faster grinding experience, then coarse grit bits are the way to go! They may grind at a quicker pace, but it's important to keep in mind that they are more prone to chipping the edge. Coarse grit bits are perfect for situations where you have lots of material to grind or if you need to speed up your process.
By using the right tools for the job, such as the fine 220 grit bit, you can ensure a smooth and flawless finish on thin or delicate glass pieces. This bit is designed to handle these types of glass with care, making it a valuable addition to any glass artist's toolkit.
