What is a Step Drill Bit?
Step Drill Bits are the most important tool when working with metals. They work at a faster speed to make relatively neat holes. Mostly used in metalworking, they come with just one single drill bit, known as a step drill bit, with progressively sized grooves and ridges.

Using Step Drill Bits for Sheet Metal Work
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.

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 do this job. This is a good technique when strengthening bolts and other attachments, as well as adding stability to various construction projects.

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 for car restoration projects, making it a costly and timely endeavor. However, with step drill bits, they can stick with the one bit and save time with less bits needed.

The 3 Cutters Come in the Following Sizes:
    • 4-12mm: 4mm,6mm,8mm,10mm,12mm
    • 4-20mm: 4mm,6mm,8mm,10mm,12mm,14mm,16mm,18mm,20mm
    • 3-12mm: 3mm,4mm,5mm,6mm,7mm,8mm,9mm,10mm,11mm,12mm

This compact set replaces more than 10 individual drill bits.
