Choose the Correct Fit
Check the included bit sizes against the job before ordering. A range does not imply every possible intermediate diameter.
Clamp the work and choose speed and lubrication for the material. Keep the drill square to the surface.
Installation & Care
Stop advancing at the selected step. The larger diameter above it will enlarge the opening if fed into the work.
Let the bits cool, remove chips safely and store them with the cutting edges protected.

Important Product Questions
Which bits are included?
Includes one each of the 4–12 mm, 4–20 mm and 6–35 mm metric step bits. The diameter ranges overlap; check each bit’s marked steps.
Can I substitute a nearby marked size?
Use the diameter specified for the fitting or fastener. Adjacent steps produce different clearances, so compare the actual sizes before drilling.
How should I choose the drilling speed?
Match speed and feed to the material and diameter. Clamp thin work securely and monitor the chosen size mark as the hole enlarges.
