Milwaukee 2PC Step Drill Bit Set #4

RAPID-START STEP BIT DOMINANCE

Engineered for the rigorous demands of multi-trade job sites, the Milwaukee 48-89-9234 set redefines drilling efficiency through high-grade High Speed Steel construction and a specialized black oxide treatment. Unlike traditional twist bits that wander and overheat, these step bits utilize a single cutting-edge geometry to maintain absolute control while producing clean, burr-free holes in everything from aluminum to stainless steel. By integrating a Speed Start Tip, these bits eliminate the need for center punching, allowing the user to initiate precise holes instantly while the dual-shank design ensures seamless transition between high-torque impact drivers and precision drill-press chucks.

• / Single Cutting Edge provides true round holes every time without the chatter of multi-flute designs.
• / High Speed Steel (HSS) Make-up delivers superior heat resistance for extended service life in ferrous and non-ferrous metals.
• / Speed Start Tip reduces bit walking and allows for faster penetration in sheet metal and thick plate.
• / Laser Etched Markings withstand heavy abrasion to ensure long-term visibility for accurate hole sizing.
• / 1/4″ Hex and 3-Flat Shanks offer versatile compatibility with both impact drivers and standard three-jaw chucks.
