When shopping for driver bits, you may come across power bits. They are available in many of the same drive types as insert bits. Power bits, however, feature a unique design that distinguishes them from all other types of bits.
Overview of Power Bits
Power bits are characterized by their ability to fit directly into a power tool. They don’t require the use of a bit holder. To use a power bit, you can place it directly in the tool’s chuck. After tightening the chuck, the power bit will be secure and ready to use.
Common drive types for power bits include the following:
- Phillips
- Slotted
- Hex
- Square
- Torx
How Power Bits Work
So, how do power bits work exactly? As shown in the photo above, power bits feature a groove near the base of the shank. This groove allows them to fit securely in the chuck of a power tool.
Power tools that support power bits are typically spring-loaded. They have a spring or similar mechanism in the chuck that pushes against the bit. If you inspect a power bit, you’ll notice it features a groove between the shank and base. This grove will align with the spring so that the power bit remains stationary in the chuck.
Power Bits vs Insert Bits
Most tool bits can be categorized as a power bit or insert bit. Power bits are designed to fit directly into power tools, whereas insert bits are designed to fit into bit holders.
Insert bits are available in the same drive types as their power counterparts. The difference is that they require the use of a bit holder. To use an insert bit, you’ll need to place the bit in a specialized holder. You can then attach the bit and holder to your power tool.
Benefits of Power Bits
Power bits offer several benefits. Most people will agree that they are easier and more convenient to use than traditional insert bits. With a power bit, you don’t have to worry about trying to fit it into a small bit holder. Instead, you can place the power bit directly in the tool’s chuck.
Power bits offer better control than insert bits. Insert bit may move slightly in the bit holders with which they are used. Even a small degree of movement can have a negative impact on the accuracy of your fastening applications. This isn’t an issue with power bits, though. Since they connect directly to power tools, they don’t move around.
