Designed for speed, accuracy, and durability, the #1 Step Drill Bit (1/8 in–1/2 in) is a versatile solution for creating clean, precise holes in metal and plastic. Engineered specifically for high-speed cordless drills, it delivers faster drilling performance, extended bit life, and improved battery efficiency, allowing you to complete more work on a single charge.
Its advanced dual-flute construction efficiently clears chips and debris, ensuring smooth, jam-free operation while boosting cutting speed. This design minimizes resistance, helping maintain consistent performance and reduce wear over time.
The optimized cutting geometry, paired with a corrosion-resistant black oxide finish, limits heat buildup and friction for enhanced durability and long-lasting sharpness. As a result, the bit cuts through steel and other materials with greater control and efficiency.
For added precision, the Rapid Strike Tip enables fast, accurate starts, while the 3-flat secure-grip shank reduces slippage in the chuck. Laser-etched size markings remain easy to read, helping you stop exactly at the desired hole diameter every time.
