1. Dremel Ultra Saw – Expanded Versatility

The Dremel Ultra Saw is a 3-in-1 power tool that is engineered for rip cutting, flush cutting, plunge cutting, and surface prepping. This great tool is powered by a heavy-duty 7.5-amp motor to tackle the toughest applications.

Specs

  • Powered by a 7.5-amp motor
  • Rated speed of 13000 RPM
  • Two cutting wheel positions
  • 4” blade diameter and 3/4” cut depth
  • Dust port for connecting a dust port adapter
  • Metal front end / guard

The Dremel Ultra Saw is a 3-in-1 tool, which is great because it offers you expanded versatility for ripping, flush and plunge cutting, and surface preparation.

This tool is powered by a heavy-duty 7.5-amp motor that has an impressively fast rated speed of 13000 RPM for handling the toughest applications.

The saw has two cutting wheel positions for added flexibility. The first position is for all your plunge and straight cuts, while the second position is for making flush cuts.

The unique design is integrated with an adjustable depth guide, which not only allows you to control the depth of cut, but also provides you a clear line of sight for more precision.

It has a great ripping capacity thanks to the large wheels and power motor, which means you can make clean cuts in a variety of materials, such as wood, tile, metal, plastic, and masonry.

The Ultra Saw accepts the US600 flush cut blade, allowing you to easily make flush cuts into plywood, hard/soft wood, plastic, PVC, drywall, laminate flooring, and even the composites.

But the thing is, it’s possible to receive a model with a very poorly machined or chipped soleplate with a visible crack.

Another inadequacy of the Dremel Ultra Saw is the lack of some appropriate tools in some kits. For example, the US40-03 kit provides you with a masonry blade instead of the surface prepping wheel.

Pros

  • Three-in-one design offers extended versatility
  • Powerful motor generates first cutting speed
  • Two cutting wheel positions for added flexibility
  • Adjustable depth guide improves control over cuts
  • Provides a clear line of sight for greater precision

Cons

  • Some models may come with a chipped soleplate
  • Doesn’t come with a dust port adapter

Conclusion

The Dremel Ultra Saw was engineered for users who want more from a circular saw in terms of advanced features, superior versatility, unmatched performance, and long-lasting durability.

Overall Rating – 4.6

2. Dremel Saw Max – Easiest Model to Use

The Dremel Saw Max is a good quality tool system that gives you the ability to make all your common cuts with confidence. It can easily cut through everyday materials, such as wood, plastic, drywall, plywood, and more.

Specs

  • Powered by a 6-amp motor
  • Rated speed of 17000 RPM
  • 3” blade diameter and 3/4″ cut depth
  • Adjustable depth control
  • Clear line of sight and precision
  • Two cutting wheel positions

This compact tool is powered by a very powerful 6-amp motor that generates a speed of 17000 revolutions per minute for cutting through wood, plastic, and metal among others.

With an unparalleled view of the task at hand, the Dremel Saw Max makes quick work of tough materials, all with the ease of one-handed operation.

This innovative tool has an adjustable foot on it, which is great because you can range the depth cut manually from 0 to 3/4-inch. There’s also a lever to lock the foot into position.

I really appreciate the paddle switch mechanism with a trigger, considering how easy it is to ensure that the unit doesn’t start on its own until you are ready to operate.

It has a lock button feature at the back. So, if you will be using the saw for an extended period of time, you can lock it into the on position until you’re done cutting.

The standard saw blade sit recessed behind a guard to add a level of protection, while the flush cut blade extends to the exterior, allowing for effective flush cutting.

But the tool is a little bulky, which makes corner work challenging, and the non-standard blade (3-inch) isn’t of the best quality because it tends to wear out faster than usual.

I also don’t like how the saw gets hot too quickly when working on a slightly larger work piece, and how easily the blade guard and plastic shoe deform when cutting metal.

Pros

  • Delivers super-fast cutting speed for a compact model
  • Provides exceptional one-handed operation
  • Guiding the blade manually is extremely easy
  • Features a convenient trigger switch for added safety
  • Two cutting wheel positions for straight, plunge, and flush cuts

Cons

  • Non-standard saw blades wear out too fast
  • It gets too hot when used continuously

Conclusion

The Dremel Saw Max is engineered to be a go-to tool for making all of your small-scale do-it-yourself cuts on a regular basis.

How To Pick The Right Portable Circular Saw

Here are the main things that you have to take into account when picking the right product:

Motor Position

There are two types of circular saws you will come across on the market with respect to the position of the motor: sidewinders and worm drives.

Sidewinder

The motor armature on a sidewinder spins parallel to the blade arbor, and the motor is mounted off to the side.

By nature of the gear of a sidewinder, the motor is usually in line with the spinning saw blade. This automatically means the blade spins fast.

For woodworkers and others who don’t expect heavy, everyday use of a circular saw, a quality sidewinder is probably the way to go.

Worm Drive

In this type of circular saw, the motor’s driveshaft is at right angle to the blade arbor. Worm drive gears transmit the power from the motor to the blade.

The worm drive design is one of the most powerful one in the circular saw family. It can rip through anything you throw at it.

The durability and high torque of the worm drive mechanism has earned this type of circular saw a bulletproof reputation among woodworkers.

The fact that the blade is mounted to the left side of the motor, makes the blade and the cut line more visible when you’re using the saw.

Like running a standard transmission engine in a low gear, the saw trades speed for power. With higher torque, the worm drive design can cut through thicker and harder materials.

The benefit of torque is the ability to keep the blade going through the hardest of materials, such as metal, without going dull too fast.

Cut Line Indicator and Blade Visibility

Another important consideration is the cut line indicator. This feature will help you line up the blade to the cut line, which is important when making precision cuts.

A great marker will precisely define both sides of your saw’s blade curve. This allows you to cut either to the left or right side of your line.

In addition to a great cut line, you need superior blade visibility. All cutting projects require you to have a clear line of sight because you’re not always going to see your saw’s cut line indicator.

Blade Diameter and Depth of Cut

Circular saws are generally described by their size. For example, 3-inch, 4-inch, 7-inch and the like. This size represents the maximum blade diameter that the saw will accommodate.

Thus, a 4-inch saw will accept blades of a diameter up to and including 4 inches. This specific size is generally considered most desirable by most do-it-yourselfers.

Larger diameter circular saws that are more expensive are available, but they are intended for larger projects, such as construction.

The depth of cut is also related to the blade size or diameter of the blade. With each 1/2-inch of blade diameter, only 1/8-inch of cutting depth is gained.

So, it is important you know what thickness the saw will be able to cut, both at a 90° angle and 45° angles. Also, an adjustable depth control feature is a great asset.

Dremel Saw Max vs Ultra Saw – What Are The Main Differences?

These two products are siblings, but one is an improvement of the other. Let’s find out which one of the two stands out as the better option for your do-it-yourself projects.

Here are the most important comparison factors:

Amperage of the Motor

A better representation of power when comparing Dremel Saw Max vs Ultra Saw is the amperage rating.

Amperage, as you may know, is the current produced by an electromotive force of one volt acting through a resistance of one ohm.

I compared the Saw Max to the Ultra Saw on the basis of amperage required at low and high speed. The Ultra Saw has a higher amperage, which means more cutting power.

Blade Diameter and Depth of Cut

The Dremel Saw Max has a blade diameter of 3 inches, while the Dremel Ultra Saw has a blade diameter of 4 inches.

The large blade size of the Ultra Saw allows you to use it with a blade guard without affecting the cutting capacity. Both saws have a depth of cut of 3/4-inch.

You should know that the larger blade diameter of the Ultra Saw will allow you to effectively make deep cuts compared to that of the Saw Max.

Construction

The Ultra Saw all-metal design makes it slightly heavier in weight at 6.75 pounds, while the Saw Max weighs 6.4 pounds.

The shoe and the guard of the Ultra Max are all metal, but the Saw Max has plastic guard and shoe. This clearly tells you that the Ultra Saw is the better option for cutting metal.

Both of these units have a compact, portable design that offers one-handed operation. And they both have a convenient power button and trigger switch.

But you will clearly notice that the adjustable foot of the Saw Max is black in color and that of the Ultra Saw is silver in color. This distinction is important because it affects your visibility of the cut line.

Versatility

Both the Saw Max and Ultra Saw can do straight, plunge, and flush cuts on the following materials: soft and hard wood, laminate flooring, composite, plywood, tile, plastic, PVC, drywall, and masonry.

But only the Dremel Ultra Saw can do surface prepping (metal, tile, masonry and concrete) in addition to plunge, straight, and flush cuts. This feature allows you to remove rust and corrosion from metal.

Kits & Accessories

You have various purchase options in terms of kits and accessories for each model.

Dremel Saw Max

The available purchase options for this model are:

  • SM20-03: This tool kit contains the Dremel Saw Max, a wood and plastic blade, and a metal cutting blade.
  • SM20-02: This tool kit includes the Dremel Saw Max, a hard carrying case, a blade guide, a vacuum suction accessory, a flush cut blade, a metal cutoff wheel, a tile blade, and a wood & plastic blade.

Dremel Ultra Saw

The available purchase options for this model are:

  • US40-01: With this kit, you get the Dremel Ultra Saw, a diamond surface prepping grinding wheel, a flush wood cutting blade, a metal cutoff blade, a wood cutting blade, an auxiliary handle attachment, and a storage bag.
  • US40-03: With this kit, you get the Dremel Ultra Saw, a masonry blade, a metal cutoff wheel, a wood flush cut blade, a wood cutting blade, an auxiliary handle attachment, and a storage bag.

Final Thoughts

The Dremel Ultra Saw is an upgrade of the Dremel Saw Max; so, we expect it to give a better performance than the latter.

But, as far as compact circular saws are concerned, the Saw Max is lighter, more compact and portable with an exceptional one-handed operation.

The Saw Max also comes fully equipped for the job with a variable depth guide, trigger lock-out, and a dust extraction port.

The Ultra Saw is engineered for versatility. While the Saw Max can make plunge, straight, and flush cuts, the Ultra Saw can make all the mentioned cuts as well as surface prepping.

The Dremel Ultra Saw wins hands in the versatility of Dremel portable circular saws for do-it-yourself projects. But the inclusion of a dust port adapter of the Dremel Saw Max wins in ensuring a dust-free workspace.
