Comparison Review: Dremel Ultra Saw vs RotoZip


I love DIY. Years ago, minus any power tool, I was able to make a spice rack. This was my first major project and it took me about two weeks to complete. It took me days to prep and cut wood by hand. I used a basic handsaw, wood plane and good old sandpaper to prep my materials. It took me a few more days to put it all together with a hammer and finally hand painted my project.

Compare my first spice rack project with a recently accomplished project which only took me a day to complete. I used a compact cutting tool to make a two-tier bookshelf for my rec room. I still remember measuring wood, cutting it piece by piece and constructed everything by hand. However, cutting and prepping my materials were too easy with my compact and powerful handsaw.

I have learned that handsaws can be very handy especially when you are cutting small pieces of wood and materials for a project. I have also learned that sometimes you need a compact tool to cut more efficiently and cleanly than a motorized heavyweight cutting tool. And when it comes to compact tools, a few brands seem to stand out. Dremel, known for its handy, compact and lightweight tools has the Dremel Ultra Saw.

The Ultra Saw is the answer to projects that require a powerful yet portable cutting tool. I have used a few Dremel power saws but this one has a small, compact body that weighs barely 7 pounds. But don’t let its size and weight fool you. The Dremel Ultra Saw is a versatile 3-in-1 tool that goes beyond cutting materials. It can also be used to rip through plywood, cut through metal and prepare materials for projects. It comes with a tough 7.5 – amp motor meant for tough cutting applications and for making fast cuts. There are many amazing features of the Ultra Saw making it a good addition to your worksite or workshop.

On the other hand, the RotoZip is something that you must check out. The RotoZip is a spiral saw that can make cuts faster, cleaner and more controlled. It can move through almost any kind of material including wood, drywall, sheet metal, laminate flooring, plexiglass, granite, ceramic tiles, cement boards and tough solid surfaces. The RotoZip is tough and very versatile which can make plunge cuts. It comes with a variety of or compatible ZipBits, XBits and XCores, to work with different materials. The RotoZip’s power stems from its 5.5 amp motor at 30000 rpm. All these good features make this compact spiral saw a good tool to add to your worksite or workstation.

Buyer's Guide

How to pick the right product

When you are in the market for a portable saw, you need to place quality over all other features. You need a tool that will match your needs and will give you years of good use. Check the following important parameters to find the best portable power tool that’s right for you.

  • Do you need a portable cutting tool or a regular power saw?

Remember that a portable saw could only take a specific length and thickness of material and therefore you might want to consider a regular power saw when cutting thicker and larger materials instead. If you want to cut shapes and intricate patterns then a scroll saw or a reciprocating saw would work best.

  • Choose a power tool with a reliable motor

Look for a portable cutting saw with a high motor rating. The higher the tool’s motor rating the more effective the tool is to cut a variety of materials and will be able to work on different projects. A motor with high wattage will spin the blades faster and increases the RPM. Higher RPMs will improve tool performance which means it can cut thicker, tougher and more complicated materials for any project or application.

  • Select cutting capacity, cutting depth and bevels

A power saw with good cutting capacity is the best kind of portable saw. The cutting capacity tells you if the tool can cut the material you are working on. Ideally, the power saw’s maximum cutting depth should be 0”. The base plate should be easily adjustable to cut bevels easily. The portable saw must also be able to cut from 45 to 90 degrees so it can be used on a variety of applications at the worksite or workshop.

  • Check for complete accessories

Portable cutting saws are sold in kits or sets, however, there are power saws that are sold as a bare tool. Power saws insets are a good way to save money because you don’t have to spend more money by buying accessories and tool parts. The most common accessories that you will find in portable power saw sets are blades, wrenches, guards and a bag to carry your power tool around.
