NEO TOOLS porraspora 4-32 mm HSS 15 porrasta

Drilling clean, precise holes in thin sheet metal, plastic, or wood often requires multiple drill bits and constant bit changes. This step drill bit eliminates that hassle by combining 15 progressively larger diameters into a single tool, allowing you to create holes from 4 mm to 32 mm without swapping bits. Its self-centering tip ensures accurate starts, while the straight flute design clears chips efficiently for smooth, burr-free results.

Who is it for

This step drill bit is ideal for electricians, HVAC technicians, metal fabricators, and serious DIYers who frequently drill into thin materials like steel, non-ferrous metals, plastics, and wood. Whether you're enlarging existing holes or drilling new ones in panels, junction boxes, or enclosures, this bit saves time and delivers professional results.

Tips

Use a center punch to mark the drilling location for even greater accuracy. Apply cutting fluid when drilling steel to extend bit life and improve hole quality. For best results, use a drill press or a steady hand with a corded/cordless drill at moderate speed. Clean the bit after each use and store in a dry place to prevent corrosion.
