Step drills - Import export

Step drill bits are engineered for versatility and efficiency in metalworking applications. These bits feature a unique stepped design that allows for drilling multiple hole sizes with a single tool, reducing the need for multiple bits and saving time. Constructed from high-quality carbide and often coated for enhanced wear resistance, these step drill bits provide clean, burr-free holes in various metals, including stainless steel and other alloys. They are indispensable tools for professionals in electrical, HVAC, and sheet metal fabrication sectors.

When drilling, it is vital to ensure than concentricity is < 0.02 mm. The fundamental problem when drilling: if the cutting forces are high, the feed rate must be reduced. The same factors apply when step-drilling.
