FAQ

1. Benefits and Disadvantages to Step Drill Bits
When it comes to using a step drill bit on a project, the biggest advantage is saving a lot of time when working. When using basic drill bits, a person has to take the bits off and replace them with different bits when a new sized hole needs drilled. With the step drill bits, one size pretty much fits all. They are also easier to maneuver and have faster drilling.
2. Using Step Drill Bits for Sheet Metal Work


The most popular job that uses step drill bits is sheet metal working. The step drill bits are best used on thin materials, which fits the description of sheet metal. Sheet metal work also requires a number of different sized holes, meaning that workers would need to constantly change their drill bits. Since one step drill bit can change to a number of different sizes, time is saved by using them with sheet metal work. These also last longer and drill faster than other drills with sheet metal.
3. Using Step Drill Bits for Countersinks


Another purpose of step drill bits is to use them as countersinks. Since these are so versatile, they work very well when fastening screws and fasteners beneath a surface. When drilling holes in the opposite side of materials, the smaller bits here are perfect to accomplish this task. This is a good technique when strengthening bolts and other attachments, as well as adding stability to various construction projects.
4. Using Step Drill Bits for Auto Repair Work


Another great use for step drill bits is on auto repair projects. Most auto body shops use many multi-stepped bits in a number of car restoration projects, making it a costly and timely endeavor. However, by using the step drill bit, they can stick with the one bit and save a lot of time with less bits needed. These can help install chrome on the body panels easily, since those pieces usually require holes of different sizes.
