ITEM: HSS Step Bit Set (3 Piece Set)
ABOUT THIS TOOL:
- 3-piece metal set
- HSS steel with titanium coating
- dimensions: 4-12 mm / 4- 20mm / 4-32 mm
WHAT IT DOES:
A Step drill bit is primarily used to drill holes in sheet materials up to 1/8″ thickness. You can also use it to enlarge existing holes. Step drill bits allow you to cut different size holes without changing the bits.
HOW TO USE IT:
Find the center of the hole. Measure well and mark better. Punching an indentation in a metal sheet or a plastic sheet will get you off to a better and much more accurate start so that you only have to drill once. The dent marks the spot and makes the drilling more exact.
