This step drill bit is designed for fast, precise hole drilling in both small and large diameters. Ideal for steel and plastic, it is optimized for high-speed cordless drills, offering up to twice the drilling speed, up to four times longer bit life, and up to 50% more holes per battery charge.
The dual-flute design efficiently removes chips and debris, ensuring smooth, jam-free operation while maintaining consistent cutting speed. Its precision-engineered geometry and corrosion-resistant black oxide coating reduce heat from friction, enhance durability, and keep the cutting edges sharp and straight for faster, cleaner metal cutting.
Equipped with a Rapid Strike Tip, a 3-flat secure-grip shank, and laser-etched size markings, this step drill bit provides accurate centering, easy hole-size identification, and reliable stopping at the desired diameter, preventing bit wandering and slippage for professional results every time.
