Sometimes you just have to cut a bolt, maybe the bolt is stuck or maybe it has become so rusty that it is impossible to get off. The Dremel tool is perfect for these kinds of jobs, it is small enough to get into most tight places, and it uses high-quality cutting discs like the ones on your angle grinder, just smaller. <\/p>\n\n\n\n

Trust me, bolts and other metals are easy to cut with the Dremel. But it is important to do it properly, even if the Dremel is a relatively small power tool it can still do some damage. So let’s go through the process step by step.<\/p>\n\n\n\n

How To Cut A Bolt With Your Dremel <\/h2>\n\n\n\n

1. Use Safety Glasses And Gloves<\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Safety is the BEST, don’t you agree. When cutting metal with a Dremel, safety is actually very important. Cutting discs can break and come flying at you (has happened to me before), there will be sparks from cutting the metal, and as a general rule, we always use safety gear around power tools. <\/p>\n\n\n\n

As a minimum, we use safety glasses to protect our eyes from metals and broken cutting discs. Use the type of safety glasses that completely covers your eyes and does not leave any room for materials to reach your eyes. You can also use a safety visor. <\/p>\n\n\n\n

In general, gloves and power tools do not match that well<\/strong>, because the gloves can get caught up in the moving parts of the tool and become a security risk. But when cutting metal with a Dremel, I personally choose to use gloves to protect my hands from sparks and hot metal<\/strong>. Decide what works for you.<\/p>\n\n\n\n

A tool like a Dremel might still be able to do some harm if your glove gets caught up in the cutting bit. But it\u2019s not nearly as powerful as something like an angle grinder for example.<\/p>\n\n\n\n

2. Use The Right Dremel Tool<\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

In this article, I’m going to focus on using the Dremel Rotary Tool<\/strong>. If you have a Dremel 3000, 4000, 4300, 8220, or a similar model, you can use it for cutting metal. <\/p>\n\n\n\n

If you have a less powerful Dremel like the Dremel Stylo+, it will take longer to cut through the metal bolt and be hard on the tool. I know that the Stylo+ is not meant for heavy-duty jobs like cutting bolts. <\/p>\n\n\n\n

3. Choose The Right Cutting Bit<\/h3>\n\n\n\n

We have to choose the right bit depending on the thickness of the bolt we are cutting. I recommend using the Reinforced Cutting Wheel For Metal Cutting <\/a>99% of the time. This is the most reliable bit used to cut metal with the Dremel, it is also the thickest and widest metal cutting bit. <\/p>\n\n\n\n

The reinforced cutting bit uses the EZ-Lock mandrel #EZ402. <\/p>\n\n\n\n

The largest bolt a Dremel can cut has a diameter of 2\/3-inch (1.7 Cm). Cutting a bolt this large with your Dremel will be hard on the motor and wear out the bit fairly quickly. <\/p>\n\n\n\n

You can also use the smaller and thinner metal cutting bits for cutting bolts with the Dremel, but they are more brittle and have a bigger chance of breaking while cutting. And I do not like shards of cutting wheels to come flying at me so I try to avoid them. The smaller bits used to cut metal are the #420 Cutting Bit<\/a> and the #EZ409 Cutting bit<\/a>. <\/p>\n\n\n\n

4. Mark the Cut And Make A Plan<\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Use a marker to mark on the bolt where you are going to do the cut. It can be hard to make a straight cut in metal with the Dremel. But the mark will definitely help as a reference. <\/p>\n\n\n\n

You also have to take into consideration how you are going to do the cut. Sometimes bolts are located in tight places which can be hard to reach. Do you need to use the smaller flex shaft<\/a> to reach it, or maybe you need to use the ri<\/a>g<\/a>ht-angle attachment<\/a> to get the angle right<\/p>\n\n\n\n

!Important:<\/strong> The cutting of metal will produce sparks. Make sure you are not cutting metal close to any flammable material. <\/p>\n\n\n\n

5. Set Your RPM<\/h3>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Now we have located, marked, and planned out our cut and we are ready to start cutting bolt. Set the RPM on the Dremel between 30000 – 35000, or the highest speed\/RPM your Dremel can get to. <\/p>\n\n\n\n

If it is your first time cutting metal with a Dremel, it can seem intimidating to use such a high rpm, it is best to use a high RPM but it is fine to use a lower RPM if that makes you feel safer. <\/p>\n\n\n\n

Here is a demo I made, which shows how the Dremel<\/strong> performs when cutting a bolt.<\/strong><\/p>\n\n\n\n
