Dremel vs Micromotors

Introduction

In this blog we explore Dremel Vs Micromotors. We look at the differences between Dremels and micromotors for precision finishing and the different consumables for use on each. 

What is the difference between a Dremel and a Micromotor?

A Dremel is a brand of rotary tool that is commonly used for a variety of tasks such as grinding, cutting, sanding, and polishing. It’s a versatile tool often used in DIY projects, crafts, and small-scale construction. The term “Dremel” has become somewhat synonymous with rotary tools.

On the other hand, a micromotor is a type of rotary tool as well, but it typically refers to a smaller, more precise rotary tool used in specific applications like precision engineering, jewellery making, dental work, mechanical surface finishing or other intricate tasks. Micromotors are often preferred for their higher precision and lower vibration compared to standard Dremel tools. They are designed to be lightweight and ergonomic, allowing for greater control and accuracy in fine detail work.

Benefits of using a Micromotor

Micromotors offer several benefits over Dremel tools, particularly in certain specialized applications:

1. Precision: Micromotors are designed for precision work. They often have higher RPM (rotations per minute) ranges and better torque control, allowing for delicate and precise movements. This makes them ideal for tasks such as precision engineering, engraving, jewellery making, and dental work where fine details are crucial.
2. Size and Ergonomics: Micromotors are typically smaller and more lightweight than Dremel tools, making them easier to handle for extended periods and in tight spaces. Their ergonomic design reduces fatigue during prolonged use, especially in tasks that require intricate movements.
3. Low Vibration: Micromotors are engineered to minimize vibration, resulting in smoother operation. This is essential for tasks that demand steady hands and accuracy, such as carving, engraving, or delicate woodworking.
4. Specialized Attachments: Micromotors often come with a range of specialized attachments tailored to specific tasks, such as right angled heads, belt sanders. These attachments enhance versatility and performance in various applications.
5. Quiet Operation: Compared to larger rotary tools like Dremels, micromotors tend to operate more quietly. This is advantageous in environments where noise reduction is important, and health and safety is important.
6. Less Risk of Damage: Due to their precision and lower power output compared to Dremels, micromotors are less likely to cause damage to delicate materials or substrates, where the integrity of the material must be preserved.
7. Low Heat Generation: Micromotors typically generate less heat compared to larger rotary tools, which is advantageous when working with sensitive materials or components that may be susceptible to heat damage.

Advantages of Dremels

1. Accessibility: Dremel rotary tools are widely available and come in a range of models to suit different budgets and needs. They are commonly found in hardware stores and online retailers.

2. Cost: Dremel rotary tools can be more affordable compared to micromotors, especially for hobbyists or occasional users who may not require the precision and features of a micromotor.

Size of spindle for Dremel and micromotor consumables

Dremel

The most popular size of spindle for use on a Dremel rotary tool is the 1/8″ collet. This size is commonly used because it accommodates a wide range of Dremel accessories, including cutting bits, grinding stones, sanding drums, and polishing wheels. However more and more, especially in the UK Dremels can be purchased with a 3mm collet for 3mm spindles. 

However, it’s worth noting that the popularity of spindle sizes can vary depending on the specific tasks and preferences of users. Some users may prefer smaller collet sizes (such as 1/32″ or 1/16″) for finer detail work, while others may prefer larger sizes for heavy-duty tasks. Ultimately, the most popular size of spindle for your Dremel will depend on the types of projects you frequently undertake and the accessories you use.

Micromotor

Micromotors generally take the following spindle sizes. And if not, you can easily change the collet to accommodate a different spindle size.

1. 2.35 mm (3/32 inch): This is a common size for many micromotors and is compatible with a wide range of accessories, including burs, drills, and grinding tools.

2. 3.0 mm: Some micromotor handpieces use a 3.0 mm spindle size, which is slightly larger than the 2.35 mm size. This size is also compatible with various accessories for detailed work.

3. 1/8 inch (3.175 mm): Some micromotors may also use a spindle size equivalent to the 1/8 inch size commonly used in Dremel rotary tools. This size offers compatibility with a wide range of accessories.

Where can I get consumables for use on Dremels and Micromotors?

As we make many consumables here at Moleroda in the UK we can often make consumables on whichever size of spindle you want. Just give us a call to discuss your needs.

We sell a huge variety of mounted polishing or deburring products. These come on both 3/32 spindles and 3mm spindles and even 1/8″.
