How to use

Secure the step drill bit in a suitable drill chuck and set the drill to a steady speed appropriate for thin sheet metal. Position the tip at the marked drilling point, apply moderate and consistent pressure, and allow the bit to progress through the material step by step until the desired diameter is reached. Reduce speed when nearing the final step to achieve a cleaner edge.

Recommendations

Use cutting lubricant appropriate for sheet metal to improve surface finish and extend bit life. Clamp thin sheets or use backing material to prevent deformation and burrs. Wear appropriate eye protection and follow standard safety practices when drilling.
