Are technological advances sufficient to justify the replacement of aging equipment that is still in working order? Response on a case by case basis...
And the batteries?
The evolution in terms of battery was made by the power. After 7.2 volts of the first drill models, the 18 or 24 volts are now commonplace. Especially since it is not always easy to get new battery packs for older devices. And if the batteries are made from 1.2-volt batteries coupled, it is often difficult to replace them yourself because the elements constituting the block are usually glued and not screwed. Buying a new lithium battery pack to put it in the place of an old nickel-cadmium block is a bad idea. Indeed, lithium batteries are systematically coupled to an electronic control system... integrated in the heart of the machine and not in the battery pack. The only exception is the 18-volt Ryobi battery ("One +" range) where the dedicated lithium electronics are located in the power supply. These machines can therefore operate indifferently with the old nickel-cadmium blocks or with the new lithium ones.
A good chuck
The classic metal mandrel has long been the only reference. Strong and resistant, we could just blame him that it requires the use of both hands and a specific key to change tools.
• Became rare, this type of model is now replaced by a mandrel which, if it remains manual tightening, is much faster to use. Metal is always present in its manufacture, but a cladding comfortable to the touch often ensures the dressing.
• These new chucks use two techniques: two-handed or one-handed. In the first case, you must grasp both crowns and tighten or loosen. In "one-handed" version, the machine is equipped with a shaft lock, at the push of a button or, even simpler, an automatic lock when the engine is stopped.
Think about recycling
Some manufacturers include in their specifications the recycling of their old machines, through their dealer networks. It is therefore up to the user to deposit his used equipment at the point of sale. The collected machines are then directed to a reprocessing center of the manufacturer.
After relegating to the museum chignoles and other tampons, drills have also lost ground against machines lighter, better equipped and, above all, wireless for battery models.
Is it necessary to replace its tools every time? For example, a drill in good condition may very well remain permanently on a piercing column, placed on the corner of the bench.
Which longevity for which tool?
But on the solid side, do not bother thinking that older models were stronger than recent ones. It has been a long time since manufacturers design machines according to users.
For a range intended for professionals, they incorporate motors, bearings and electronic components capable of withstanding long hours of operation under harsh conditions.
On the other hand, for a range intended for private customers (so-called "general public"), it is the manufacturers' design offices that establish the criteria for frequency and duration of use. Results, machines less resistant to intensive use. Nobody is surprised to see his drill break after ten years, while its use over this period is actually less than a year of work in the hands of a professional. Moreover, the guarantees often stipulate mentions of the type "except for professional use".
A time criticized, imported fabrications from China no longer frighten the do-it-yourselfer. Major brands manufacture their machines there, in order to reduce the cost price through cheap labor. But they say that quality is at the rendezvous because they control all the manufacturing. It is true that the average price of the portable electric has increased very little in recent years and that we sometimes find, over the test benches, slight decreases on the same model present in the catalog for several years.
Tools under what warranty?
At the same time, the "no name" (no-brand tools) are more and more present on the shelves of do-it-yourself superstores. Often of average quality, they do not discourage some tinkers who see the opportunity to "bypass" the system.
Assuming that the machine can not claim to last long, given its ridiculous purchase price, they play on the warranty period of two years. They then use the device thoroughly during this period, do not hesitate to ask for replacement at the first malfunction (the tool is under warranty), and find the opportunity to make a good deal.
Old tools: and security?
As arguments that also encourage renewal of its equipment, we must mention security. Thus, the safety release that begins to integrate the perforators is not negligible. In case of blockage in full drilling, instead of bending your arms due to the rotation of the machine around the drill, everything stops clean...
The circular saw
The principle of the tool has evolved little and a model of the 1980s in good condition will perform the same work. On the other hand, on the models of last generation, the grip is much more ergonomic. Guiding side of the cut, some even include a laser convenient. Finally, the guide rail was more the domain of the professional machine, it begins to be integrated into the consumer market.
To keep or not?
The must in this area is to offer a plunge saw with its guide rail. To you the opening of the windows of embedding on plan of kitchen, in full panel!
The drill ended up adding a real plus: a reverser of the direction of rotation. An advantage to screw, but also to clear the drill bit or the drill when drilling deep enough (perforations for injection into a wall). The screwdriver has evolved in the same way: the slotted screws that accounted for most of the sales have given way to new impressions (Torx, hexagon socket, square...) more suitable for this type of screwing because the tip has less tendency to rip.
To keep or not?
At a time when bonding and screwing has become a common fastening method, the screw-and-unscrew function, associated with a speed adjustment, is therefore essential. If you do not own a battery-powered screwdriver, buying a new drill model can be a real versatile tool.
Much more effective than a drill, even percussion, the puncher is no longer reserved for professional tools. Largely developed for the do-it-yourself market in the 1980s, it has become essential to tackle vibrated concrete. With a "chiselling" style, blowing up old tiles or staking masonry joints can be done effortlessly. The power of the motor associated with the electro-pneumatic strike also makes it possible to realize cylindrical embedments (electric sockets) with a tungsten carbide drill bit.
To keep or not?
Your faithful percussion drill can not pretend to compare! No need to spend time refurbishing it, it is outdated.
From the beginning, the adaptation of the mechanism of the sewing machine to the world of handymen was unanimous. The rotation of the engine has thus turned into a fast round-trip movement that drives the blade. If the old models still in activity continue to perform their primary function - sawing and singing occasionally - there are many developments separating them from the newcomers.
First of all, the principle of sawing very "mechanical" is coupled with a pendulum movement, closer to the natural gesture of a manual sawing. When this movement is engaged, the blade tilts forward to the climb, to distribute the attack of the toothing on the whole race. On descent, the blade moves back to reduce friction and evacuate sawdust. The difference is obvious in terms of speed. But the quality of "finishing"
of the cut is in slight withdrawal.
In addition, for ages, the assembly of the blade required a screwdriver or a hex key to remove the collet. Today, "tool-less" fastening systems are becoming more widespread. Most often, it involves raising a lever to release the clamping of the blade clamp.
But the maneuver can also be done by rotating a wheel.
To keep or not?
For sawing, you can always trust your old jigsaw if it is well maintained and its sole has not taken the game side eased in the work, it remains to wish that she let go one day to finally know the pleasure of a blade change without tools and to play the pendulum movement during rough flows.
The electric plane
Not really obvious technical evolutions for this tool. Much faster and just as accurate as a manual model, it has a cylindrical carrier, driven at high speed by its electric motor. The models are usually solicited in a very punctual way by DIYers, resulting in a long life. Notably, reversible irons that are changed occasionally are not always easy to find at regular retailers, as are the drive belts. Finally some brands do not even exist anymore (Peugeot for example).
To keep or not?
From the moment the cylinder is in good condition and the irons sharpened, you can keep your old electric plane. In anticipation, if it gives you any satisfaction, buy two sets of reversible irons and even a notched belt drive in advance. You will be safe from a break in supply.
From roughing work to finishes, including polishing, the eccentric sander remains the reference tool in the do-it-yourself basic set. Faced with the belt sander that is confined to large jobs and vibrating dedicated finishes, the eccentric shows real skills in areas as different as woodworking or bodywork. Initially, these machines were offered with a Ø 115 mm tray. Today, most adopt the Ø 125 mm or even 150 mm top. This allows for a larger work surface and a more powerful engine. Technically, no clear evolution for thirty years, apart from better designed suction systems and the appearance of filter cartridges significantly reducing dust.
To keep or not?
If you wear a dust mask systematically, you will not be bothered with an old eccentric sander. Same goes for vibratory sanders and belt models. Of course the ergonomics are more careful and handling better, but it is worth to maintain these sanders as long as possible... The sanding difficult to reduce the life expectancy.
