Milwaukee #1 Step Drill Bit 1/8" - 1/2" 48-89-9201
RAPID PENETRATION PRECISION
When you're cycling through panel installs or custom metal fabrication, the last thing your fleet needs is bit walking or thermal failure. The Milwaukee 48-89-9201 Step Drill Bit is engineered specifically for the cordless world, optimizing chip evacuation and reducing heat build-up that kills lesser bits. The 1/4" hex shank allows for instant transitions in high-torque impact drivers, while the dual-flute geometry ensures a burr-free finish that meets the highest professional standards for fit-and-finish.
- / JAM-FREE PERFORMANCE: Dual-flute design optimized for high-speed cordless drills provides greater control and prevents material seizing.
- / RAPID STRIKE TIP: Eliminates the need for center punching by creating fast, accurate starts with significantly less heat generation.
- / LASER-ENGRAVED REFERENCE: High-visibility markings ensure you stop at the exact required diameter every time, preventing over-drilling.
- / BLACK OXIDE FINISH: Enhances durability and provides superior resistance to corrosion while maintaining lubricant capacity for heavy metal applications.
