For a definition of the head styles shown as "Others", go to the search page by clicking on one of the head drive pictures and there you will see all of them listed with their common name.

You can shop for a screwdriver power bit by clicking on any of the pictures above or Search our database for a specific screwdriver power bit or Browse our catalog index. When you click on one of the pictures you will go to our search page for power drive bits of that particular point style. All of the many sizes are in our database so that you can make a choice quickly.

Reduced diameter bits are ideal for driving screws below the surface of drywall or other application where the bit must be smaller than the head of the screw. If you have this type of application, look for a bit with a long "turned length" and a small body diameter. Turned length is the distance from the bottom of the hex drive portion of the bit to the bit point.

If you should want a bit that is good for poorly recessed Phillips screws, a wider tip design fills out an inexact recess to make better contact. Look for the phrase "For Shallow Screw Recesses" in the "Features" pull down menu on the "Search" page. You may also want to consider a "Frearson" drive bit. the Frearson recess is designed so that any size bit will fit any size recess. Choose bits on the basis of body diameter -- the larger the screw, the larger the body diameter.

Choosing the proper heat treat for screwdriver tools is important in achieving long tool life. Different applications, different operators, and different power tools require different heat treats. We offer a choice of three heat treat hardness levels in many or our screwdriver bits to match the particular customer's application. These heat treats are specified by a letter suffix as follows:

        X - The hardest heat treat available (this is also the default value)
         I  - Intermediate hardness
        R - Lowest Hardness

Selecting the heat treat best suited for a particular application may require some trial and error. The proper heat treat depends on the failure mode. If the bit breaks or shatters, select a bit with less hardness. If the failure mode is wear, select a harder bit. Many times both breakage and wear may occur within the same application. This can be due to a number of factors such as a different operator, different torque values, and different power tool settings.

In general, high torque application require "R" heat treats to withstand twisting and resist breakage. The "X" heat treat is most suitable for low torque applications, particularly if hardened screws are used.

If a failure occurs, a change in hardness may result in better service. The "X" heat treat is most common and should be selected unless the specifics of an application or an existing problem would suggest using "I" or "R" hardness.

To specify a particular heat treat, we simply add a letter suffix to the part number. For example to specify "X hardness" in a #2 Phillips insert, the part number would be the standard 10 digit number 1011SBnnnnX. Not all bits are available in all heat treats. Special heat treats can be supplied for a particular application. Contact us for specific recommendations. If no number is appended to the 10 digit part number then the heat treat default value is "X" and the price shown is based on the "X" heat treat.

These insert bits are normally sold in minimum quantities.
