A die grinder is a must-have tool for the mechanics and DIY enthusiasts who want finesse in their works. It a must have in every toolbox as it offers tremendous versatility and it can work on various types of materials.
Die grinders come in various shapes and sizes. They are rotary tools and they have a very high RPM rate. Some of the high-quality die grinders can rotate with a speed around 25000 RPM.
You’re probably struggling with the die grinder if you’re a beginner. In this article, we have gathered some important die grinder tips that will help you grind better with greater precision.
The process of grinding may seem like a fairly easy job at the first look, however, if you don’t put the appropriate pressure and blade then you might end up with a sloppy result. The cutting tools vary considering the type of material you’re working on.
Some Basic Tips to Follow
- Always read the instruction manual if you’re working with the tool for the first time.
- Never use the tool if you’re don’t have the proper safety gears on.
- Don’t use the tool if there’s any bystander, especially children.
- Don’t exceed the recommended pressure rate and rpm
- Make sure the workstation is clean and tidy so that you don’t accidentally trip over the weld.
- It’s an absolute must to disconnect the air supply to the tool if you’re going to change the cutter or the stone.
- Clean the tool after every use and keep in a secured place out of the reach of children.
- Before turning on the device, ensure that the cutter is properly fixed to the tool.
Always Wear Safety Gears
Working with any sort of power tools bear some risk factors. It’s always better to be safe than sorry. Make sure you wear the proper safety gears before operating with a die grinder. It’s a common scenario to have flying bits and sparks while working with a grinder. To avoid any accident wear a full face visor and high-quality goggles to keep your eyes and face safe.
Make sure you’ve Chosen the Right Grinding Tool
Die grinders come with multiple grinding tools and cutting stones. These tools vary in sizes and shapes as they are used for various different applications. The color of the cutting stones usually varies so that you can easily figure out which tool is suitable to perform which application.
Use the Correct Tool
Not all disc or cutter will deliver the same performance on different materials. Make sure the tool that you use has the right amperage to perform the job. Invest in a good grinder even if it means spending some big buck on it rather than getting a flimsy grinder that provides mediocre performance. A grinder with a high-quality disk will provide a better result on all sorts of materials.
Keep an Ammeter Handy
An ammeter is a common tool found in every workshop. However, if you don’t have one around then get your hands on one immediately. The pressure generally varies depending on the type of material you’re working on. The optimum pressure usually lies somewhere between 8 amps to 10 amps. An ammeter helps you to figure out whether you’re pushing the grinder too hard or too low.
Take a Look at the Spark Flow
What do you do if you don’t have an ammeter handy? Well, in situations like that, the perfect way to figure out the optimum pressure is to look at the spark flow. If the grinding procedure is going properly then the spark should fall off about 3 to 4 feet away from the weld. If the sparks are falling too close or too far off then you’re doing it wrong.
Put a Uniform Pressure throughout the Process
Grinding with a die grinder is surely not rocket science but it doesn’t involve some techniques. We tend to put more pressure as we push the disc forward and reduce pressure as we move the disc backwards.
However, putting too much pressure will result in over-heating and glazing of the disc grains. To get an effective grinding result, the key to keep a consistent pressure, not too hard or too gentle.
Listen to the Sound
If you’re working at a constant speed then the grinder will also make a noise of constant pitch. If the pitch goes down the usual level then it means you’re not putting up the optimum pressure and it delivers a more screechy sound then it means you’re putting too much pressure on the weld.
Die grinder is one of the most useful tools in every workshop. It has a number of uses and it’s a really handy device that will make your welding process a lot more hassle-free and precise. Not everyone is familiar with the operation process and the usefulness of this amazing tool.
Operating a power tool do involve some risks. However, safety features should never be taken lightly. Always take proper precautionary methods and wear the proper gears when you’re working with a die grinder or any other power tool.
There are no certain rules for using a die grinder. However, following these die grinder tips above will help deliver a more flawless and effective result with lesser effort.
