It consists of a handle and a socket. The handle is the wrench. On the ratchet handle is a mechanism that allows the ratchet to engage and reverse the direction of the ratchet to loosen or tighten fasteners like nuts and bolts. Sockets are tools that attach to a rachet, torque, or socket wrench. The socket is placed on the square extension or driver of the ratchet. A ratchet and socket combination allows the user to turn a fastener a bolt or nut without having to reposition the tool on the fastener.
If you were using a wrench you would definitely have to reposition it after each turn. Ratchet and socket make operating in tight corners more manageable because there is little to no space for a wrench to be leveraged. The first of the additional settings is the double ratchet. In this position, the ratchet mechanism works to turn the drill bit in a clockwise direction whether the handle and drive wheel are turned one way or the other. This allows for quicker drilling than the setting which only allows the drill bit to turn in a clockwise direction, as the drill bit is turned clockwise on both the forward and back strokes of the handle.
The final setting on a 5 way ratchet is a spindle lock. In this position, the drill is locked in place and will not turn. This position is useful for when you really need to tighten the chuck up onto a drill bit or if you need to replace the chuck.
How to tell the difference between a 3 way and 5 way ratchet If you do not have a user manual for your hand drill, then the easiest way to tell if the ratchet is a 3 way or 5 way mechanism is to count the number of positions that the ratchet can be set in. If the ratchet can only be set in 3 positions then it is a 3 way ratchet mechanism, if it can be set in 5 positions then it is a 5 way ratchet mechanism.
For more information on ratchet setting positions see our page: How to alter the ratchet setting of a hand drill or brace Should I choose a 3 or 5 way ratchet and why? The main advantage in choosing a 5 way ratchet is if you need to drill lots of holes quickly in a confined space that will not allow you to make a complete turn of the turning handle. By using the double ratchet setting, the turning handle can be moved back and forth in the space available to drill into the workpiece.
However, hand drills can no longer be purchased new with a 5 way ratchet mechanism, due to the lack of demand for such a specialised tool, especially with electric drills being preferred by most people now. A hand drill with a 3 way ratchet will be more than adequate in most situations, and due to their greater availability, they are likely to cost far less than an old hand drill with a 5 way ratchet.
What does point mean when talking about ratchets? Many hand drills or braces will be advertised as having a point reversible ratchet. This means that the gear within the ratchet mechanism has 12 teeth. So the pawl will engage the ratchet mechanism every 30 degrees.
The more points or teeth a ratchet has, the more frequently the pawl will engage the ratchet mechanism, allowing it to be used with smaller movements of the handle and so in more confined spaces.
What is the difference between an enclosed and an exposed ratchet? And I'm building a proper studio where we can be more productive, more creative and shoot in even better quality. Read more.
I've had quite a few questions from people about why I chose to use an MX5 Miata for the video series. Was it sponsored?
Am I an expert with them? Because I love them? The answer is Now, with hindsight, I realise it was the best possible choice in the world. Here's the story We've been filming and releasing videos every week since getting into the new studio. The course now has 9. We're using CGI anywhere it helps understanding, and the general quality and feel of the videos is at an all-time high.
I'm probably writing about the The Video Course - check it out! Drive sizes.
