## Summary description

Step drill bit FANAR designed for drilling holes from 4 to 20 mm in one tool. Made of HSS (high-speed steel) for increased wear resistance and suitable for drilling thin sheet metal, plastics and non-ferrous materials. Single-piece stepped geometry enables progressive hole enlargement without tool changes, useful for production, maintenance and repair tasks.

## Long description

Step drill bit FANAR Wiertło wielostopniowe Ø 4–20 mm HSS is a single-piece stepped drilling tool designed to create holes from 4 mm up to 20 mm in one operation. Manufactured from high-speed steel (HSS), this step drill bit provides increased wear resistance and consistent cutting performance when working with thin sheet metal, plastics and non-ferrous materials. The stepped geometry allows progressive enlargement of the hole without changing tools, reducing setup time for repetitive or varied-diameter drilling tasks.
Advantages
The HSS construction gives the step drill bit durability and heat resistance for extended use in light industrial and workshop environments. The single-piece design ensures concentricity and reduces vibration compared with multi-component bits. Stepped cutting edges provide controlled chip evacuation and smooth hole entry, producing clean holes across the 4–20 mm range. One tool covers multiple diameters, simplifying tooling requirements and saving time on small production, maintenance and repair jobs.
Suitable for
Drilling thin sheet metal such as steel panels and aluminium sheets
Working with plastic components and polymer panels
Creating progressively larger holes in non-ferrous materials like copper and brass
Maintenance, repair and light production tasks requiring multiple hole diameters
Key specifications
Diameter range: progressive steps from 4 mm to 20 mm
Material: high-speed steel (HSS)
Design: single-piece stepped geometry for multiple diameters
Intended material use: thin sheet metal, plastics, non-ferrous metals
Typical mounting: standard drill chuck compatible shank
How to use
Mount the step drill bit securely in the drill chuck and set the drill to a suitable speed for the work material; use lower speeds for thicker or harder metals and higher speeds for plastics. Apply steady, moderate feed pressure to allow the cutting edges to engage progressively through each step. For best results on metal, use appropriate cutting fluid to reduce heat and improve chip evacuation. Retract the bit occasionally to clear chips when drilling deeper holes or when working with poor chip-breaking materials.
Usage recommendations
Use appropriate personal protective equipment (eye protection, gloves) and clamp workpieces firmly. Match drill speed and lubrication to the material type and thickness to extend tool life and maintain hole quality.
