Ideal for precision work on small surfaces, this power tool is as easy to handle as it is versatile. Equipped with multiple accessories, it allows for a wide variety of jobs.
Mini-tools: for what uses?
Mini-tooling is a must for model making but its uses have diversified over time, with the increase in engine power (175 W here).
This tool allows to intervene on almost all types of materials (plastic, glass, wood, metals, faience). A wide range of accessories and fasteners allow a wide variety of jobs: sanding, carving, engraving, routing, cutting, polishing and cleaning. It operates on battery or mains (230 V or powered by a 9 V transformer).
Beginners and experienced DIYers will find their account.
Getting started well studied
Like a pen, the ergonomics of the tool have been designed for natural handling.
A non-slip tapered ring improves the comfort of use a little more. For long work, which requires concentration and precision, a flexible shaft, equipped with a stylus, can be adapted to the head of the device. For metal cutting or sanding, the motor block is covered with non-slip rubber to be held in full hands. A handle can be added for a better grip, taking care however not to obstruct the vents.
Test the device before using it
The device tested (Dremel 4000) is very easy to use.
In any case, it is always useful to become familiar with a tool before actually using it.
Do not hesitate to weigh it and look for the best balance point.
Practice on recovery media to judge its operation at full load and get used to the various accessories offered.
Dose the pressure
Do not exert too much pressure on the device to avoid bending the shaft or jamming a disc when cutting.
Lightly apply the rotating accessory to the surface to be machined: it does the work, it remains only to focus on the guidance.
When cutting, grinding or engraving, do not start directly on the workpiece. Wait until the tool has reached its maximum speed, then apply it smoothly on the material. Finally, we must know that we obtain a better result by performing several passages.
Choose the right speed
The machine is equipped with an electronic system allowing the progressive start, which avoids the effects of torque at start-up.
It is also equipped with a variable speed drive ranging from 5,000 to 35,000 rpm. While the majority of tasks can be accomplished using the maximum speed tool, some materials, such as plastic or polystyrene, which melt at low temperatures, must be cut at reduced speeds, between 5,000 and 15,000 rpm.
Polishing, polishing and wire brush cleaning must also be done at a reduced speed, so as not to damage the accessories and workpiece. Higher speeds (between 15,000 and 35,000 rpm) are ideal for working with wood, metals and glass, as well as for drilling, carving, cutting and smashing.
The engine block and all accessories (65 total for our device) are supplied in a hard plastic case. Very practical, it allows to store and protect small tools after use, and especially not to misplace them.
Sets of chucks, drills and milling cutters, sanding discs, polishing, cutting: a complete range of accessories (supplied) allows to tackle all styles of small jobs.
After having selected the desired accessory, the "chuck clamp" must be adapted to the diameter of the tool shaft. Thread it into the bore of the motor shaft and tighten the nut without tightening it.
Change tool easily
Assembly and disassembly of the tool are easy. Engage it to the bottom of the chuck. Press the lock button and tighten by hand. Finish with the service key.
Once the tool is plugged into the mains, push the switch to start it.
The button remains locked in this position during all use.
A wheel can regulate the engine speed and find the right speed depending on the chosen accessory and the material to work.
The good ergonomics of the engine block and the anti-slip coating of the conical ring make it easier to grip.
The most delicate work becomes possible.
A set of drills of different diameters makes it possible to drill wood and metal.
As an option, a drilling column ensures perfect perpendicularity of the tool.
The cutting guide facilitates grooving (like a router) and straight cutting. It fits on the head of the machine.
A gauge measures the depth of attack of the cutter.
Make cuts, circular grooves and holes
By replacing the parallel guide with a point, it becomes possible to make circular cuts and grooves with a maximum diameter of 30 cm.
It is a very useful accessory to make a hole in thin materials (tiles, paneling...), to ensure the passage of a cable, a pipe or a switch.
Fit the cutting discs
Ø 32 mm cutting discs are specially designed for cutting metals. They are mounted by clipping on a spring plate.
Cut out the metals
The cutting of the metal takes place at 35,000 rpm.
At this speed and without too much pressure on the tool, the Ø 32 disc has no trouble in overcoming a curtain rod.
Fit the hose
To mount the hose (supplied), remove the grip ring, nut and clamp.
Position the nut, then screw the hose onto the ring thread.
On the tip of the stylet, refit the chuck and the locknut.
Inox button blocks the tree.
Start-up is done with the engine block switch.
The stylus is ideal for engraving, carving or model making that requires concentration, patience and precision.
It allows to work longer without the weight of the tool that is still around 660 g. A bracket (optional) facilitates the work and avoids being cluttered by the machine.
A removable precision grip, covered with a non-slip coating, allows a safer grip of the device.
Convenient for precision work.
Precautions of use
• Wear protective glasses
• Before changing accessories, unplug the tool
• Place the mini-rotary tool after the accessory stops completely
• Dust regularly the vents
• Beware of backlash (or back torque): hold the tool firmly to prevent the accessory from being ejected if it becomes blocked.
