How to Use – Get Professional Results Perfect for Every Job Site
Pro Tips:

Use low speed (300-500 RPM) for metal – Apply cutting oil to reduce heat and extend bit life  HSS4241 Titanium Coated Step Drill Bits With Hex Shank
Use medium speed (800-1500 RPM) for wood and plastic – Apply steady, even pressure without forcing
For stainless steel – Use slow speed and cutting oil; let the tool do the work Cobalt Step Drill Bit
Clear chips periodically – Remove debris from steps during extended cuts to prevent clogging
