Milwaukee NITRUS Carbide Extreme Drill Bit | Universal Open-L Fit (49-25-1563)

Meet the Milwaukee NITRUS Carbide Extreme

The Milwaukee NITRUS Carbide Extreme (model 49-25-1563) is designed to take on metal drilling tasks with steady precision. It combines a carbide-tipped edge with a robust body, aiming to deliver reliable performance across common metals. The Open-L universal fit expands compatibility beyond a single brand or chuck, making it easier to pair with a wide range of drills in your shop or on a job site.

The design prioritizes durability and consistency, which can help you maintain steady progress through multiple holes without frequent bit changes.
