![]() ![]() Standards organizations define sets of sizes that are conventionally manufactured and stocked. Metric drill bit sizes define the diameter of the bit in terms of standard metric lengths. The case that holds them in an indexed order (by size), via a graduated series of holes, is called a drill index. Metric drill bit sizes Metric drill set, 1.0–6.0 mm by 0.1 mm, jobber length. Ī comprehensive table for metric, fractional wire and tapping sizes can be found at the drill and tap size chart. The British Standards on replacing gauge size drill bits with metric sizes in the UK was first published in 1959. In nearly all other countries, metric drill bit sizes are most common, and all others are anachronisms or are reserved for dealing with designs from the US. In the U.S., fractional inch and gauge drill bit sizes are in common use. They can be made in any size to order, but standards organizations have defined sets of sizes that are produced routinely by drill bit manufacturers and stocked by distributors. You can do this only if your driver has an extension.Drill bits are the cutting tools of drilling machines. Usually, measuring one inch in length, you can use deep sockets in inaccessible places. In such cases, mechanics use deep sockets. In some cases, it might not touch the nut before the bolt hits the end of the socket, which makes the job hard and sometimes not doable. The shallow socket is the other name for a normal socket. So, if you need a socket for lightweight jobs, go for the 12-point socket. They are considered more durable and sturdier than the inner walls. In such cases, the 6-point sockets are less likely to slip or move. The 6-point socket is used for heavy jobs that require the application of heavy or substantial torque. However, there’s another category to this socket known as a 6-point socket. The 12-point sockets are usually meant for light household tasks. So, even if you’re a newbie, you can easily use it, as there won’t be an alignment problem. You can easily slip this socket over the tool in any of the available 12 positions. Such sockets, especially the 12-point one, are very easy to fit and use. Point Sockets: Next on our list are the point sockets. ![]() And impact sockets get the job done here as they are sturdier and more robust than conventional sockets. Now, for such tools, you need sockets that are sturdy and can withstand high torques. Impact sockets are specially designed to fit in such tools.įor example, let’s suppose you’re working with a pneumatic or electric wrench. And this is where impact sockets come into the picture. However, most socket types don’t attach with such tools. It’s because they are old school and have a sturdy build. Impact Sockets: Most of the time, people prefer hand tools. If you’re in the mechanical field, you’ll find the below information useful. There are different sockets suited for different jobs. It’s used for precision or interior jobs. You can use such drives for small sockets with a maximum size of 14mm.
