Milwaukee Thunderbolt 21PC Black Oxide Drill Bit Set 48-89-2801

REINFORCED CORE TECHNOLOGY FOR MAXIMUM JOBSITE DURABILITY

The Milwaukee Thunderbolt Black Oxide Drill Bit Set is engineered for high-torque applications where standard bits frequently fail. By utilizing a significantly thicker web—the core of the drill bit—these bits provide superior structural integrity and protection against side-load breakage during aggressive drilling. The parabolic flute design is a critical mechanical advantage, ensuring that chips and debris are ejected rapidly to maintain a lower operating temperature, which directly extends the service life of the cutting edge. For professionals requiring immediate engagement in metal, wood, or plastic, the 135-degree split point eliminates walking, allowing for precise hole placement without the need for a pilot hole or center punch.

• / 135° Split Point Tip starts on contact to prevent bit walking and ensure precision hole placement.
• / Thunderbolt Web features a thicker core that resists snapping under heavy side-load pressure.
• / Parabolic Flute geometry clears chips and dust faster to reduce heat build-up and friction.
• / Black Oxide Coating provides enhanced corrosion resistance and thermal management for long-term ROI.
• / Customizable Accessory Case is fully compatible with the PACKOUT modular storage system.
