Understanding Cordless Screwdrivers

Cordless screwdrivers are versatile, portable, and efficient tools that use battery power to drive screws into various materials such as wood, metal, and plastic. They are an invaluable addition to any DIY toolkit, as they save time and effort compared to manual screwdrivers.


Advantages of Cordless Screwdrivers

  • Portability: Cordless screwdrivers are not tethered to a power outlet, allowing you to work in tight spaces or areas without electricity. 
  • Speed: They significantly reduce the time it takes to complete tasks compared to using manual screwdrivers. 
  • Precision: Cordless screwdrivers offer greater accuracy and control, minimizing the risk of damaging materials or stripping screws. 
  • Versatility: They can be used for various tasks, including assembling furniture, installing fixtures, and repairing appliances. 

Types of Cordless Screwdrivers

Straight Screwdrivers

Straight cordless screwdrivers have a linear design similar to that of traditional manual screwdrivers. They are ideal for light-duty tasks and are often more compact and lightweight than other types of cordless screwdrivers.


Pistol Grip Screwdrivers

Pistol grip cordless screwdrivers resemble a handheld drill with their grip and trigger mechanism. They offer more torque and power, making them suitable for heavy-duty tasks and driving screws into dense materials.


Adjustable Screwdrivers

Adjustable cordless screwdrivers feature a pivoting handle that can be locked in various positions, allowing you to switch between straight and pistol grip configurations. This type of screwdriver offers increased versatility and is ideal for working in tight spaces or at awkward angles.


Key Features to Consider

Torque

Torque refers to the rotational force generated by a cordless screwdriver. A higher torque rating indicates more power, allowing you to drive screws into denser materials with ease. Consider your specific needs and the type of tasks you will be performing when selecting a cordless screwdriver with the appropriate torque rating.


Speed

The speed of a cordless screwdriver is measured in rotations per minute (RPM). Higher RPMs allow you to drive screws faster, which is particularly useful for larger projects or professional applications. Some models also feature variable speed controls, enabling you to adjust the speed according to the task at hand.


Clutch

The clutch is a crucial feature that allows you to control the torque output of your cordless screwdriver. It prevents over-tightening and stripping of screws by disengaging the motor once the desired torque level is reached. Look for a model with an adjustable clutch for maximum control and precision.


Power and Battery Life

Voltage

Voltage is a measure of the electrical power provided by the cordless screwdriver's battery. Higher voltage batteries produce increased power and torque, making them suitable for heavy-duty tasks. However, they can also be larger and heavier than lower voltage models. Common voltage ratings for cordless screwdrivers include 3.6V, 7.2V, and 12V.


Battery Type

Cordless screwdrivers typically use one of three types of rechargeable batteries: Nickel-Cadmium (NiCd), Nickle-Metal Hydride (NiMh) or Lithium-Ion (Li-ion). NiCd and NiMh batteries are more affordable but have a lower energy density and shorter overall lifespan compared to Li-ion batteries. Li-ion batteries are lighter, hold their charge longer, and have a higher energy density, making them the preferred choice for most users.


Charging Time and Run Time

Consider the charging time and run time of a cordless screwdriver's battery. Faster charging times and longer run times allow you to complete tasks more efficiently. Some models also offer replaceable batteries, enabling you to swap out depleted batteries with charged ones for uninterrupted work.


Ergonomics and Design

Weight and Balance

A well-balanced and lightweight cordless screwdriver will reduce fatigue during extended periods of use. Look for a model with an ergonomic grip and evenly distributed weight for maximum comfort and control.


LED Work Light

An integrated LED work light is a useful feature that illuminates your workspace, improving visibility and accuracy in low-light conditions.

Accessories and Additional Features

A cordless screwdriver is a versatile tool that can be further enhanced by various accessories and additional features, making it even more adaptable to numerous tasks and projects. When selecting a cordless screwdriver, consider the following accessories and features to ensure you can tackle any job with ease and precision.

Bit Types

Ensure that the cordless screwdriver you choose is compatible with a wide range of bit types, including Phillips, slotted, square, and Torx bits. This will enable you to tackle various tasks and projects with ease. Some cordless screwdrivers come with a starter set of bits, while others may require you to purchase bits separately. Investing in a comprehensive bit set will provide you with the flexibility to handle diverse projects and materials.

Bit Holders and Extensions

Bit holders and extensions can provide additional reach and accessibility when working in tight spaces or at awkward angles. Magnetic bit holders keep your bits securely in place during use, ensuring a stable and precise driving experience. Bit extensions allow you to access hard-to-reach areas, increasing the versatility of your cordless screwdriver.

Right Angle Attachments

Right angle attachments are designed to change the direction of the drive, enabling you to drive screws perpendicular to the axis of the cordless screwdriver. This accessory is particularly useful for tasks that involve working in confined spaces or around obstructions.

Flexible Shaft Extensions

Flexible shaft extensions are another valuable accessory that can help you maneuver around obstacles and drive screws in tight spaces. The flexible shaft can be bent and twisted to various angles, allowing you to reach areas that would be otherwise inaccessible with a standard cordless screwdriver.

Drill Bits

Some cordless screwdrivers also function as light-duty drills, enabling you to create pilot holes or small holes in various materials. In such cases, it's essential to have a selection of drill bits compatible with your cordless screwdriver. Look for a cordless screwdriver that offers compatibility with standard drill bit sizes and types, such as high-speed steel, brad point, and masonry bits.

Magnetic Screw Holder

A magnetic screw holder is a practical accessory that holds screws securely in place while you drive them, reducing the risk of dropping or losing screws during use. This feature is particularly helpful when working in tight spaces or at elevated heights, where dropping screws can cause delays and frustration.

Carrying Case

A carrying case is a practical accessory that protects your cordless screwdriver and keeps all related components organized and easily transportable. Look for a durable case with compartments for your cordless screwdriver, charger, spare batteries, and various bits and accessories. Some cases also include belt loops or shoulder straps for easy transportation and accessibility on job sites.

Best screwdriver bits for electric drill - Practical Machinist

My Bosch cordless electric drill came with two 2 inch combo (Phillips/slotted) bits. One of two things about the drill I didn't like (everything else I love - it's a super drill). The bits got chunged up pretty easily.

Do all bits wear quickly? What are your guys favorite screwdriver bits for electric drills? Ideally, I'd like the kind that are about 5 inches long, made from hex stock, so that I could chuck the bits directly and tighten screws without having to get the drill so close to the work. And of course, it would be best if they wore like hardened tool steel.

As good as all top brand names are good. The cheap ones are cheap for a reason. What does surprise me is the "Phillips/slotted" as I can't even remember the last time I used a slotted bit. Even Phillips are becoming a thing of the past and Torx is by far the best.

What was weird for me Gordon, was that the bit that got chunged up rapidly came with my (Swiss-made) Bosch drill.

Here, slotted screws are present in some older furniture and tools. And to drive a Posidriv screw one should really use a Posidriv driver, as a Phillips will cam out (Phillips were designed to cam out, to limit torque in assembly). Most hardware stores here still stock mostly slotted and Phillips. So Phillips gets a lot of use. So I don't think that Phillips/slotted is so weird. If you are installing curtain rods in you house, do you really use a Torx?

I think slotted/Phillips is less surprising than would be a Frearson/Mortorq combo bit. Maybe in Canada one would get a Robertson/BNAE combo.

Seriously, though, as I looked through the Apex catalog I was overwhelmed with the choices. Definitely a case were too many choices causes paralysis. Phillips ACR? Phillips ACR II Plus? Which size Torx? For that matter, which size slots and Phillips? I think Cooper Tools is really, really missing an opportunity here. They should have standards such as Fabricator's, Machinist's, Mechanics', and Millwright's bundles. I think that they'd increase sales by eliminating folks being overwhelmed by the number of choices. Dumbest thing it the world is trying to get just a few more driven screws out of a used-up driver bit. It's a matter of some skill to hold the drill driver on axis consistantly. When the driver bit slips off-axis the force concentrations lead to distortions of tiny cotact areas causing it to lose fit in the screw's driving recess leading to "cam-out".

Driver bits don't last long anyway. The forces on the driving features are enormous and you can expect failure sooner or later - 100 to 500 screws depending on severity of use. If the driver spims once the screw head's driving recess has been damaged. Try to finish driving the screw and chances are a couple more spins wil damage screw head is so (it looks looks like a bomb crater. It may be impossible to drive or remove it with a new driver bit. It's a judgement call, but generally after a cam-out I've found it advisable to replace the driver bit AND the screw.

Once the driver starts to cam-out it's time to change the driver. No driver, no matter what brand, material or miracle of heat-treatment, can tolerate off-axis driving. When the driver bit cams out, spins out, buzzes, whatever you may call it, it's damaged, used up, toast, can never be economically used further. Cramped, awkward, just plain miserable places to drive screws are a fact of life that make precision on-axis drives nearly impossible. So if the driver bit fails early, it aint the quality of the driver, it may be ergonomics - or - even the quality of the user. Arbitrarily blaming short driver bit life on "quality" is a dumb ego game called blame the other guy. Man up, admit you sometimes err, toss the driver bit and replace it with a new fresh one.

Yes it pays to seek quality but spending 5x the money for 10% better bit life is false economy for consumable tooling. If you buy one driver bit buy a dozen. Keep an assortment with you as you work your projects. That way a new driver bit is handy when the one in use poops out. If new a bit is handy you won't be tempted to get a couple more screws out of the used-up one.

Big +1 on the 'limited clearance'-type narrow-nosed #2 PH bits. They sit deep in the screw head and won't 'cam out' near as easily as broader points. MSTB. I buy 'em in 10-packs at Menards or other home centers for <$10. (25-packs now?) They aren't up to hammer drilling and can shatter when a panhead bottoms out against metal, but nuthin' I've seen outlasts them in general use.

Example: My brother & I hung 23 sections of stockade fence to existing posts and made up two 4' gates (lotta 3 1/2" screws into posts) using one bit and bunged up only 1 or 2 screws the whole time. There was enough life left to drywall the ceiling of a 15'x 25' family room before the extension's magnet let 'er fall out and disappear. (OMG, another ~$.80 down the drain. ) Wera - Wiha only for me. Its not much more and it gets a hell of a lot more than 10% extra life that forest quotes. Mind you, it does take some operator skill to see the real benefits, good drill, good bit and good fixings and its very easy to keep it in dead perfect alignment, set the clutch and use the throttle and things will last a long time.

Key is making sure you have the right bit either Philips or pozidrive and that it fits the screws well!

IMHO though good bits realy show through when it comes to removing stuff others put up, When the heads are half chewed, paying 5x the cost for the bits can pay back in just a few screws removed easily!
