Parts of a screwdriver

Handle

The handle is cylindrical and widest part of the screwdriver. It is used for griping during work time. Normally it is made of hard and durable plastic, wood or metal. The handle should be comfortable so that people can feel comfort during maximum torque.

Shank

The shank is thinner than handle. Normally it is made of hard steel. It attached to the handle and the blade. It can be long, medium or short. The long shank will provide more torque than a short shank.

Blade

The blade can be seen in flat head screwdriver.

Tip

The tip is the end of the blade or shank. Actually the classification of the screwdriver depends on this part of the screwdriver. Normally it is made of steel. When you use a screwdriver always try to use exact matching tip; never use a wider or narrow tip. If we use a wider or narrow tip, then it may damage the surface of the workpiece or screw or tip. The tip may be magnetic to easily grab on to the screw. Some of the screwdriver has detachable tip; in this case it is known as bit. Normally it is shown in a set of screwdriver where contains one holder and several bits.

Philips screwdriver

The Philips screw driver contains a cross or a four star point, hence they are known as cross screwdriver. You can apply more force or torque with these screwdriver compare to the flathead screwdriver. These types of woodworking screwdriver have less possibility to slip out.

Philips designs this screwdriver and the screw in 1930s; this is why the name is Philips screwdriver. They can be small, medium or large. Further some screwdriver such as Pozidriv, Frearson, Supadriv looks almost similar to this but they are slightly deference. Pozidriv can provide more torque then Philips type screwdriver but their design is very complex. You can use flathead screwdriver instead of it but not with Robertson screw.
