This goes against the grain of most pros here but as a hobbyist, I prefer corded power tools when they make sense. I've had to use my reciprocating saw exactly twice in the last year. My hammer drill about 6 times. Each use was for a few minutes total.
I bought a nice Bosch hammer drill and a us-made Milwaukee sawzall. Maybe I'm naive but at my current use rate I expect they'll still work in 50 years.
If I bought them as cordless, there is no chance they'll last even half as long. The batteries will die, even without use, and they'll be new and better batteries that won't retrofit in the old cordless tools.
The one cordless tool I do have and prefer cordless is a regular drill. The one I have now is a makita that cost me $100 and if I have to replace it every ten years it's cheap enough, but I don't want to replace ALL of my power tools, especially the ones I don't use often.
What prompted this thread is I was reading up on corded impact wrenches and how they suck compared to cordless. 1/3 the torque for corded. So for that, it makes no sense to have a corded impact wrench. And since I don't need one enough to justify a cordless or a compressor and an air tool, I just go by hand.
It seems like corded tools are going the way if the Dinosaur and I'm convinced st least some of it is to force hobbyists and homeowners into replacing their tools every decade with forced obscelence.
So I want to get a few more corded power tools over the next few years before it's impossible to get a good one with a cord.
Any suggestions? For one, I think I want a regular corded drill. At least as a backup to my cordless drill if the battery dies. And maybe when my makita eventually dies completely, if I am still a hobbyist corded I buy now becomes my primary drill alongside a future drill press.
Second, what corded tools are just crap like the impact wrench.
Third, what corded tools are gradually getting worse and I need to buy sooner rather than later?

Power Source
When shopping for a drill, always consider which power source is better for you. There are two options ' corded and cordless ' both have strong and weak sides. Most drill/drivers, screw guns and impact drivers are cordless. Hammer drills are mostly corded. Other types of drills can be both of them. Cordless drills have gained popularity during the last few years due to improvement in durability of their batteries.
Corded Drills Corded drills are arguably more durable and have more strength than their cordless counterparts. Besides, you can use it for as long as you want without worrying about the batteries. The downside is that you have to work somewhere near a power outlet.
The main feature of corded drills is amperage or amp. An amp rating tells you about the current load a motor of a drill can carry. Other important indicators include wattage and voltage. Wattage is calculated by multiplying voltage by the amps. Most drills in the US have a voltage input of 120 volts, so you can only choose the amps of your drills. The higher the amps, the higher the voltage. Most drills have amperage between 5 and 10 amps, which equals 600 and watts respectively.
Cordless Drills Modern cordless drills have enough power to perform the vast variety of jobs, although their force is limited by the battery. How much power it can deliver depends on three characteristics: torque, voltage and capacity. Voltage and capacity are linked to batteries.
The battery produces voltage. The higher the voltage, the more jobs you can do with the drill. For small projects like screwing, cordless 10.8 volt drills are enough. A bit heavier jobs such as wood and soft stone require 14.4 volts. Most hobbyists will find 14.4 volts more than enough for all their projects.
The capacity of the batteries is measured in ampere per hour or Ah. For example, a 2 Ah battery can supply a current of 2 amps for one hour. Thus, the voltage indicates the strength of the drill, while Ah indicates the lifetime of one battery.

Needless to say, the battery is one of the most important features of a cordless drill. When buying one, you have to choose between nickel-metal hydride, nickel-cadmium or lithium-ion. Nickel-cadmium are the cheapest batteries that are widely used. They can work just fine in any cordless drill. However, the memory effect is huge. It means you have to empty the battery before you can recharge it. If you try to recharge it when it's not completely empty, it will remember the status of charging and will lose some of its capacity.
Nickel-metal is a better version of the previous type. It has a better performance that doesn't have the memory effect. You can recharge these batteries when you want without damaging its capacity. However, we don't recommend having deep discharges. Don't completely empty the battery because you will decrease its lifespan. It is not popular anymore because there are better lithium-ion batteries.
The lithium-ion batteries are the best on the market. They don't have any disadvantages of previous types. They have the best capacity, too. They are lighter and smaller, which is more convenient when you perform complicated projects. The only disadvantage is their price.
Speed The speed is measured in RPM or revolutions per minute, which indicates how fast the tool turns. Modern drills allow you to switch the speeds. Cheaper models have two speed settings, with the minimum speed of 300 RPM and maximum speed of 2,000 RPM.
When you can change the speed, you can perform a wider variety of tasks. However, a higher speed is not always better. For example, harder materials should be drilled at lower speeds. Besides, different materials need different speeds. For instance, if you are going to drill through aluminum, you should get a drill that can reach 2,000 RPM.
Drill Bits There are so many projects other than drilling that you can use your drill for. Drill bits are special attachments that you can add to your drill to increase its versatility. There are different bits that are suitable for different projects. The most popular are twist, spade and lip bits.
Gears Modern drills have two gears: the lower speed gear for screwdriwing and higher speed gear for rotary drilling. Older or cheaper options have only one gear, which mean you wouldn't be able to either screwdrive or drill. And if you do, you will get over-tightening or screw damage.
Torque Different torque settings mean that you can choose the level of twisting force. Use higher torque for large screws and lower torque for other operation. If you get the torque right, the clutch will disengage the drill motor to prevent damaging the screw. The torque settings depend on how hard the surface you're working on is.
