Overall, the package contains everything you will need to start your journey with your new Dremel 4300. The accessories kit is very well put together and a great one to have for general use.

Accessories: detailed look

Sanding drums and EZ lock sanding discs: These are meant for rough shaping and smoothing. They are designed for wood and fiberglass. The discs come in various grits, and the sanding drums come in different drum girths.

EZ 456 cutoff wheels: This fits the Dremel EZ lock mandrel. It is designed for slicing, cutting, grooving, and trimming various metals, including steel. This makes it a fantastic tool for all kinds of metalwork.

Felt polishing wheels – You get these discs in two sizes — 1inch and ½ inch. The kit comes with a polishing compound meant to use with the felt discs.

⅛ inch drill bit: This is a multipurpose bit used in the Dremel cutting guide attachment, which is also included with this kit.

Aluminum oxide grinding stones: These are mainly used for various kinds of metal blade sharpening. They are suitable for sharpening, deburring, and extended general-purpose grinding for most materials, including stainless steel. 

Silicon carbide grinding stone: This stone is meant for sharpening, deburring, and grinding harder materials, such as natural stones and crystals. 

Engraving cutter and high-speed cutter: These are designed for shaping, hollowing, grooving, slotting, inlaying, and making tapered holes. They are meant for wood, fiberglass, and plastic.

Carbon steel brush: This is Ideal for cleaning and removing rust and corrosion from brass, copper, or other soft ferrous metals found in tools, doorknobs, automobile parts, and electrical contacts.

Nylon bristle brush: Ideal for general purpose cleaning and polishing, especially in hard-to-reach places such as slotted surfaces.

Extra collet and collet nut: you will need to use it with your flex shaft if you have one and the cutting guide attachment that comes with the kit. These attachments won’t work with the universal keyless chuck, 

The accessories come in a nice little plastic case stored inside the main carry case.


Now let’s look at the different attachments that come with the kit. Most of these are attached to the thread where the rubberized collar is attached. The collar is used for gripping the tool as you would a pencil. A really fat pencil full of moving parts.

Dremel cutting guide: This is used with Dremel multipurpose cutting bit. It is designed for cutting grooves and slots into wood, fiberglass, drywall, laminate aluminum, and vinyl signages.

Sharpening attachment: This is the lawnmower and garden tool sharpener attachment. It is designed to be used with the aluminum oxide grinding stone (no 932). 

Shield attachment: This plastic shield is transparent, and it deflects sparks and debris. It creates a safer and more comfortable working experience, especially when working with metal where sparks are inevitable.

Sanding and grinding guide: This gives increased comfort and accuracy during these operations. 

Look and feel

The Dremel is very well designed and looks like a professional tool. The body is made of hard plastic and a few metal parts. It feels solid and made to last. 

The motor sounds well-tuned and not as loud as most would expect. The separate on/off switch slides to toggle power supply while the speed control is a rotary dial that turns smoothly. The dial is marked from 5 (5,000 rpm) to 35 (35,000 rpm). Having these two separate helps prevent unintentionally changing the speed while using the tool. It also enables you to choose the speed setting before turning it on.

Many other brands use a combination dial that turns on and then begins to ramp up the speed. This is not the optimal design as you cannot switch it off immediately if required.

The body has a lot of rubberized surfaces, making it that much more comfortable to hold and use. This is especially helpful when you are using gloves, which should be most of the time when working with a rotary tool.


It feels pretty comfortable in hand, and the air vents are designed to blow debris away from the working surface. The finger gripping area is a separate part that can be screwed on or removed if needed. You will have to remove it if you want to use a flex shaft. Since most of my engraving and design work is done using the flex shaft, I seldom use it.

However, if you want to use your Dremel 4300 like that, the grip will make it feel very secure. It has a nice rubberized surface and feels comfortable to hold. The tool’s weight is something that you can get used to over time and by taking a few breaks between sessions.

The spindle lock button has a nice fail-safe feature that stops you from pressing it when the power switch is in the on position. This prevents damage to the spindle and the lock button itself.

Another excellent little detail is that the power button sits a little lower than the tool’s surface so that it doesn’t get turned on or off while brushing against another object or surface.

Dremel has definitely paid attention to many small details that most other companies choose to overlook. As a result, it feels better and is more efficient than other best rotary tools in the market.

Pivot light: It is powered by a separate battery and has its own on-off switch. Gives better visibility in tight spaces.

What is it Good for?

So what kind of uses can you put a Dremel 4300 to? Let’s look at the various materials and projects you can use it for.


Wood: You can make small wood sculpting projects with just the accessories that come in the box. Using the sanding drums and discs to reshape a rough cut. Then using the fast cutting and engraving bits for doing the detailing work. Going back and forth between these attachments to achieve the final result and then using the felt discs with the polishing compound to finish the piece.

Fiberglass and plastic: You can use the same attachments that you would use for wood to work with fiberglass and plastic. So you can groove, engrave, sand, and polish projects like 3D printed parts.

Metal: The cutoff wheels can cut off bits of metal and then create notches, grooves, and slots in them. Then you can use the aluminum oxide grinding wheels and the shield attachment to grind and smoothen out the surfaces. You can create small metal parts or creative projects by switching between these two accessories.
