Step Drill Bit HSS For Aluminium, Stainless Steel, PP, Wood Blue - Multi-Size Set Description

Reliable under load: Wear-resistant steel construction guarantees consistent drilling performance and extended tool life for step drill bits, even in demanding applications.
Protection concept: Provides multifunctional usability with transport-friendly design via the included storage box, effectively preventing loss and damage of step drill bits.
Efficient cooling design: The step drill bit structure enables effective heat dissipation, prevents overheating, preserves the sharp cutting edge, and ensures consistent performance over time.
Smooth drilling performance: The four-flute design significantly reduces resistance and enables burr-free drilling. The advanced multi-layer cutting technology increases drilling speed.
Typical applications:
- Drilling stepped holes in metal sheets for electrical enclosures or fasteners with burr-free edges.
- Creating multi-diameter holes in thin metal panels for brackets, cable glands, or duct openings.
- DIY projects involving sheet metal or plastic where quick size changes and consistent performance save time.
