Milwaukee Step Drill Bit #3 1/4" - 3/4" Accessory 48-89-9203
MAXIMIZED HOLE-MAKING PRODUCTIVITY
In the world of high-volume maintenance and onsite fabrication, every second spent fighting bit-walk or clearing debris-clogged flutes is a direct hit to your fleet's ROI. The Milwaukee 48-89-9203 Step Drill Bit is engineered for the modern cordless reality, utilizing a dual-flute geometry that provides up to 2X faster cutting and 50% more holes per battery charge compared to traditional step bits. This isn't just a bit; it's a precision-machined solution for penetrating sheet metal and structural materials with mechanical consistency and long-term durability.
- / Rapid Strike Tip: Delivers fast, accurate starts and prevents bit walking without the need for a center punch.
- / Jam-Free Performance: Dual-flute design optimized for high-speed cordless drills to ensure smooth chip evacuation and maximum control.
- / Laser-Engraved Marks: Permanent reference markings provide instant visual confirmation of hole diameter for repeatable precision.
