What experts liked

The ergonomic handle — though strange looking at first glance — is comfortable to hold and use, with a mix of both hard and soft portions.
- Tools and Toys
The ratcheting action on the Kraftform is what makes it special. With a special tooth system, this ratcheting screwdriver can withstand up to 50 Newton metres, or 38 pounds, of torque.
- 10 Best Ranked
The Wera Kraftform Kompakt 27 (appx. $40) has an ergonomic handle with an anti-roll feature that allows you to exert a maximum of 37 foot-pounds of torque on fasteners. The fine-toothed gear allows the mechanism to engage with minimal backward turning.
- Wiki EZ Vid
These aren't inexpensive screwdrivers, but they are exceptionally well made, and will likely give you years of reliable service. If you use a hand screwdriver on a regular basis, you won't find a more comfortable driver.

It also houses multi-component and anti-roll features along with an integrated magazine.

Storage options are a carrying case, not in the shaft of the ratcheting screwdriver

I would have preferred magnetized bits

Its ratcheting mechanism starts to stick after frequent use.

An Overview On Ratcheting Screwdrivers

A ratcheting screwdriver is a handy tool that really speeds up the process of installing or removing a set of screws. It works by eliminating the need to continuously reposition your wrist with every turn of the screwdriver. Instead, the screwdriver’s handle moves, while the head stays firmly planted on the screw. If you don’t have a ratcheting screwdriver, you’ll want to invest in a set that comes with a variety of bits to help you complete just about any project around the home.

Consider how much maintenance you’re comfortable doing. If you only plan on fixing a few furniture pieces, a model like the SATA Stubby Ratcheting Screwdriver, 6-Piece is all you need. It comes with six of the most widely used bits. The bits are also easily stored inside the screwdriver’s handle, so you won’t lose them.

You’ll want to opt for a larger set if you’re more handy. The Jakemy Rotatable Magnetic Ratcheting Screwdriver comes with a total of 69 pieces that will allow you to work on your car, home and electronic devices. Inside this all-inclusive kit you’ll get a large and small screwdriver, two different extension shafts, sockets, precision tweezers and a host of steel bits.

Check the handle of the ratcheting screwdriver you’re interested in next. You want to go with a model that is ergonomically designed, as these are more comfortable and put less stress on your wrist. Some are even resistant to oil, which is great if you do a lot of work on cars. Most of the handles are designed with three different settings, but you’ll want to check and make sure this feature is included just to be sure.

Look for a ratcheting screwdriver with extra features that make it more functional. For example, the CRAFTSMAN CMHT68001 Ratcheting Screwdriver, 26-Piece comes with a magnetic pick-up tool that can quickly grab any screws you accidentally drop. If you opt for the Makita B-50289 Ratcheting Screwdriver, 47-Piece, you’ll also get a carrying case equipped with a slot for each piece in the set.

The Ratcheting Screwdriver Buying Guide

  • You might need to use an extension shaft with the screwdriver head if it isn’t long enough to meet your needs.
  • To insert a bit into your screwdriver, you’ll need to grasp the tip firmly with your thumb and forefinger. Slide the bit carefully into the hole of the screwdriver’s blade. If the screwdriver uses magnets, you only need to make sure the connection is secure. All other screwdriver bits will need to be twisted slightly to lock them in place.
  • When you’re ready to remove or change bits, you’ll need to take a dry cloth and wipe your hands free of any sweat or oil. This way you can get a good grip on the tip of the bit. All you need to do is pull the bit straight out and you’re all set.
  • Every so often, you’ll need to clean your ratcheting screwdriver. Keeping tools clean is a great way to extend the life of your tools. If the screwdriver isn’t too dirty, you can simply wipe them down with stainless steel wipes. Tools that need a deeper cleaner are better suited to the use of WD-40. You should also use WD-40 on any comfort grip handles, as these handles absorb the chemicals found in other products, which can cause them to wear out prematurely.
  • Since ratcheting screwdriver sets come in sets with varying numbers of pieces, you’ll need to divide the total cost of the set by the number of pieces to get a price per piece. This will help you more accurately compare prices, so you know if you’re getting a good deal or not. The Makita B-50289 Ratcheting Screwdriver, 47-Piece is the most affordable set on the market, although the CRAFTSMAN CMHT68001 Ratcheting Screwdriver, 26-Piece and the Jakemy Rotatable Magnetic Ratcheting Screwdriver aren’t far behind. You’ll find the SATA Stubby Ratcheting Screwdriver, 6-Piece is able to command the highest price per piece.
