Milwaukee 48-89-9221 Step Drill Bit Set, Black Oxide, Dual Flute, 3-piece

The Milwaukee 48-89-9221 Step Drill Bit Set is a professional-grade solution for drilling multiple hole sizes with efficiency and precision. This three-piece set is ideal for drilling both small and large-diameter holes in steel, plastic, and other materials, making it suitable for a variety of applications including electrical work, plumbing, and general construction.

Optimized for high-speed cordless drills with lithium-ion battery technology, these bits deliver faster hole times and longer life compared to standard drill bits. The dual-flute design accelerates drilling speed while minimizing heat buildup, protecting both the bit and your workpiece. A secure connection to your drill chuck prevents slippage, ensuring accuracy and control throughout each project.

Features and Benefits

• Dual-Flute Design: Delivers up to 2X faster hole times and up to 4X longer bit life than standard drill bits, with up to 50% more holes per battery charge.
• Rapid Strike Tip: Enables fast, accurate starts with less heat generation, extending the usable life of the bit tip.
• Black Oxide Coating: Enhances overall durability, improves hole quality, and reduces heat buildup during extended use.
